Giving Thanks for Innovation and Compassion

Physicians who manage pain tell us why they are grateful for medical technology this holiday season.

Giving Thanks for Innovation and Compassion
Pain and Movement | Nov. 16, 2021

The means to put a lovely meal on the table. The daughter sitting just a few inches back from that table to make room for the grandchild coming early next year. The ability to sit with family without worrying that the day will be marred by random, debilitating pain coursing through your body.

We all have our own reasons to be thankful this time of year, but for people like Ashleigh and Kevin, the gratitude can be more sweeping and last far longer than one day. Because these people have lived with chronic pain that once shattered their lives and, thanks to some pretty impressive medical technology – and equally impressive medical care providers – they are now particularly grateful for the moments so many others take for granted.

And the caregivers who treat these patients all day, every day, experience the same gratitude when they are able to dramatically improve others' lives.

Two of those healthcare providers, Drs. Efrain Cubillo and Eric Cornidez, treated Robert, a former Marine and young dad, who suffered through years of debilitating pain before finding considerable relief when the doctors implanted Abbott's Proclaim™ XR SCS device. They are interventional pain physicians who work out of the Pain Institute of Southern Arizona (PISA), a series of clinics that cover a large swath of the greater Tucson area.

They know Robert well. "He had excruciating pain that followed a crushing injury he suffered in the military," recalled Dr. Cubillo. "He had injections, nerve blocks, pretty much every medication under the sun. They weren't doing the job. So, we talked it through and he decided he wanted to try spinal cord stimulation. Shortly thereafter, he felt significant pain relief in his lower extremities.

"He saw a dramatic improvement in his quality of life. He's now able to study for his MBA more effectively because his mind is sharper and he isn't distracted by the constant pain. He's able to do things with his wife and little girl that he couldn't before."

Where Spine and Soul Unite
But it's not just Robert and family who benefit from this profound change in his life. "I can't describe the feeling," said Dr. Cubillo. "It's kind of overwhelming, a rush of emotions that you aren't just improving his life but his whole family's. We're in the business of making a difference through the use of technology. This is a perfect example of that."

Dr. Cornidez, who doubles as chief medical officer of PISA, likewise feels it's vital to locate their practice at the intersection of medical technology and human caring. "PISA's mission statement is, 'Through compassion and innovation, we will make a meaningful difference in the lives of individuals and communities.' My mentor always told me if you're going to be a specialist, do something special. We try to do that for our patients."

Neuromodulation can be a dramatic stage on which to showcase the impact medical technology has on many people in need. Whether it is a device that can reduce Parkinson's tremors or better manage chronic pain, the science of neuromodulation is developing both fascinating, and increasingly important, tools.

"When nerves are hyper-excitable, when they are injured, there is only so much we can do with a needle. We can try using medications, steroids, nerve blocks, but that may only work in the short-term," said Dr. Cubillo.

"For long-term, appropriate situations we want to utilize the technology that can tap into the nervous system and calm those nerves down. The only way to do that is through neuromodulation.

"The reason it's so life-changing is because patients with this type and degree of pain, have such a big pain pattern that the pain is all they're thinking about. Pain. Pain. Pain. Pain. Pain. Basically, that's their lives. How do we change that mindset?"

Yes, we know we sound like the only word in our vocabulary is "pain," but for those patients, that's their life. That's the problem.

"Air Traffic Control Center of the Nervous System"
The answer may be neuromodulation. "We know how the nervous system works, through electrical chemical signals. We can reach into those signals and alter how the nerves respond to pain," said Dr. Cubillo. "We use this technology to tap into the air traffic control center of the nervous system and modulate the signals before they reach the brain. We aren't using a nerve blocker. It's no Band-Aid. We are altering the communication pathways of the spine."

Dr. Cornidez agrees. "Neuromodulation technology has been in existence for decades and the beauty of it is that it has evolved significantly and continues to do so. Where years ago, the electrical signal was more of a distractor than anything, now the technology is so good that we can dampen the pain without the patient feeling any tingling. In addition to treating the pain, this therapy improves quality of life. People's lives are better because of this technology."

Evolving the Game
So why do some pain physicians choose to use Abbott's neuromodulation devices? "I like that Abbott listens to patients and providers," said Dr. Cornidez. "They are really trying to evolve their products by investing in research and development to create value for the people who use them."

One way to do that is by improving communication between patient and provider when trialing the effectiveness of a pain-mitigation device, prior to it being implanted. When testing whether a spinal cord stimulation device is effective for a particular chronic condition, leads are connected to an external generator to test the impact on pain-related symptoms for a trial period of five to 10 days. During this time period, doctor-patient communication is key to figuring out how effective the device is for that person, and how to optimize the experience.

Abbott's new NeuroSphere™ myPath™ digital health app is designed to document pain relief information and facilitate communication during this important period. The app allows patients to connect with Abbott support, access educational materials and, most importantly, track pain and related symptom relief progress by giving the patient a tool to chart their experiences throughout the trial period.

Dr. Cornidez appreciates that patients can now easily obtain useful content. "They now have access to experts who can handle a lot of their questions, very succinctly. They don't have to do an internet search that might give them bad information. They can also chart their progress themselves which can be a motivational tool that results in more physical activity."

In Dr. Cubillo's experience, the information he receives from myPath is both more reliable and more comprehensive than the previous practice of a patient giving more limited measures of pain relief during the multi-day trial periods. "We want to really know how they are doing and this app not only lets the person record pain relief over time but also allows for charting of functionalities. Are they sleeping better? Walking better? It's not just percentage of pain relief, but how their life is different. These are important considerations when deciding whether to place a permanent device."

As NeuroSphere Expands the World Gets Smaller
Earlier this year, Abbott launched another technological innovation designed to make communication – and life – easier for physicians and patients with implanted neurostimulator implants. The NeuroSphere™ Virtual Clinic allows for face-to-face visits just about anywhere that has a working wi-fi signal.

"This is something that physicians around the world have been asking for: when are we getting remote programming?" said Dr. Cubillo. "In Arizona, we not only have an older patient population but also, many of our people are snowbirds, out of staters during the warm months, who live here when it cools down. We wanted to make it easier for them to see us and now we can.

"We can remotely adjust settings and do reprograming of spinal cord stimulators without people, who are already dealing with pain under the best of circumstances, having to be further inconvenienced. It goes hand-in-hand with our mission to use compassion and innovation to help people and communities."

"One advantage to the Virtual Clinic that I really appreciate is that patients don't have to drive 30, 50 or 100 miles for a visit. In the course of the pandemic, this has become even more important," agreed Dr. Cornidez. "While we treat some larger communities and the city of Tucson, PISA also covers a lot of small towns, rural areas that are quite far from our offices."

More Screen Time Means More Face Time
"I have to admit I've been surprised by one advantage to using the NeuroSphere," said Dr. Cornidez. "I find myself more connected to my patients, not less. Used to be if a patient could only do a phone visit, there was a limited connection. Now, we are reading each other's expressions and that creates a stronger bond, gives it a more personal touch."

"The NeuroSphere Virtual Clinic has definitely brought us closer to our patients," said Dr. Cubillo. "We are much more likely to connect with them now because of the ease of communication. Now they are setting up quick calls to ask questions and we can follow up easier. No one has to wait a few weeks to find a good appointment time. It really helps us engage."

The doctors agree that this innovative technology has increased their ability and capacity to meet their personal, professional goals. "The reason I became a physician in the first place is to try to improve healthcare delivery in underserved areas and this platform helps us reach a lot of rural communities that we might not otherwise," said Dr. Cornidez.

"An extra bonus is since I can make adjustments efficiently through the app, I have more time to actually talk with the patient. I became a doctor because I wanted to build that kind of rapport. It's something that's very important to me," said Dr. Cubillo.

An Appreciation
The tools to reach previously underserved communities. To develop relationships with patients you are grateful to treat. The woman with the implanted device, just inches away on the desk, sitting comfortably at her home, not having to drive hours for a visit. Feeling relief that she had not known in years, her child comfortably sitting on her lap. The ability to decrease pain and improve lives…

Plenty of reasons to give thanks.

These are the experiences of this person. Individual experiences, symptoms, situations and results may vary. The placement of a neurostimulation system requires surgery, which exposes patients to certain risks. Complications such as infection, swelling, bruising and possibly the loss of strength or use in an affected limb or muscle group (e.g. paralysis) are possible. Additional risks such as undesirable changes in stimulation may occur over time. Be sure to talk to your doctor about the possible risks associated with neurostimulation.

PROCLAIM DRG

INFINITY DBS

PRESCRIPTION AND SAFETY INFORMATION
Read this section to gather important prescription and safety information.

INTENDED USE
This neurostimulation system is designed to deliver low-intensity electrical impulses to nerve structures. The system is intended to be used with leads and associated extensions that are compatible with the system.

INDICATIONS FOR USE
This neurostimulation system is indicated as an aid in the management of chronic, intractable pain of the trunk and/or limbs, including unilateral or bilateral pain associated with the following: failed back surgery syndrome and intractable low back and leg pain.

CONTRADICTIONS
This system is contraindicated for patients who are unable to operate the system or who have failed to receive effective pain relief during trial stimulation.

MRI SAFETY INFORMATION
Some models of this system are Magnetic Resonance (MR) Conditional, and patients with these devices may be scanned safely with magnetic resonance imaging (MRI) when the conditions for safe scanning are met. For more information about MR Conditional neurostimulation components and systems, including equipment settings, scanning procedures, and a complete listing of conditionally approved components, refer to the MRI procedures clinician's manual for neurostimulation systems (available online at manuals.sjm.com). For more information about MR Conditional products, visit the Abbott product information page at neuromodulation.abbott.

WARNINGS
The following warnings apply to this neurostimulation system.

Poor surgical risks. Neurostimulation should not be used on patients who are poor surgical risks or patients with multiple illnesses or active general infections.

Magnetic resonance imaging (MRI). Some patients may be implanted with the components that make up a Magnetic Resonance (MR) Conditional system, which allows them to receive an MRI scan if all the requirements for the implanted components and for scanning are met. A physician can help determine if a patient is eligible to receive an MRI scan by following the requirements provided by Abbott Medical. Physicians should also discuss any risks of MRI with patients.

Patients without an MR Conditional neurostimulation system should not be subjected to MRI because the electromagnetic field generated by an MRI may damage the device electronics and induce voltage through the lead that could jolt or shock the patient.

Diathermy therapy. Do not use short-wave diathermy, microwave diathermy, or therapeutic ultrasound diathermy (all now referred to as diathermy) on patients implanted with a neurostimulation system. Energy from diathermy can be transferred through the implanted system and cause tissue damage at the location of the implanted electrodes, resulting in severe injury or death.

Diathermy is further prohibited because it may also damage the neurostimulation system components. This damage could result in loss of therapy, requiring additional surgery for system implantation and replacement. Injury or damage can occur during diathermy treatment whether the neurostimulation system is turned on or off.

Electrosurgery. To avoid harming the patient or damaging the neurostimulation system, do not use monopolar electrosurgery devices on patients with implanted neurostimulation systems. Before using an electrosurgery device, place the device in Surgery Mode using the patient controller app or clinician programmer app. Confirm the neurostimulation system is functioning correctly after the procedure.

During implant procedures, if electrosurgery devices must be used, take the following actions:

Use bipolar electrosurgery only.

  • Complete any electrosurgery procedures before connecting the leads or extensions to the neurostimulator.
  • Keep the current paths from the electrosurgery device as far from the neurostimulation system as possible.
  • Set the electrosurgery device to the lowest possible energy setting.
  • Confirm that the neurostimulation system is functioning correctly during the implant procedure and before closing the neurostimulator pocket.

Implanted cardiac systems. Physicians need to be aware of the risk and possible interaction between a neurostimulation system and an implanted cardiac system, such as a pacemaker or defibrillator. Electrical pulses from a neurostimulation system may interact with the sensing operation of an implanted cardiac system, causing the cardiac system to respond inappropriately. To minimize or prevent the implanted cardiac system from sensing the output of the neurostimulation system, (1) maximize the distance between the implanted systems; (2) verify that the neurostimulation system is not interfering with the functions of the implanted cardiac system; and (3) avoid programming either device in a unipolar mode (using the device’s can as an anode) or using neurostimulation system settings that interfere with the function of the implantable cardiac system.

Pediatric use. Safety and effectiveness of neurostimulation for pediatric use have not been established.

Pregnancy and nursing. Safety and effectiveness of neurostimulation for use during pregnancy and nursing have not been established.

Device components. The use of components not approved for use by Abbott Medical with this system may result in damage to the system and increased risk to the patient.

Case damage. Do not handle the IPG if the case is pierced or ruptured because severe burns could result from exposure to battery chemicals.

IPG disposal. Return all explanted IPGs to Abbott Medical for safe disposal. IPGs contain batteries as well as other potentially hazardous materials. Do not crush, puncture, or burn the IPG because explosion or fire may result.

PRECAUTIONS
The following precautions apply to this neurostimulation system.

General Precautions

  • Clinician training. Implanting physicians should be experienced in the diagnosis and treatment of chronic pain syndromes and have undergone surgical and device implantation training.
  • Patient selection. It is extremely important to select patients appropriately for neurostimulation. Thorough psychiatric screening should be performed. Patients should not be dependent on drugs and should be able to operate the neurostimulation system.
  • Infection. Follow proper infection control procedures. Infections related to system implantation might require that the device be explanted.
  • Electromagnetic interference (EMI). Some equipment in home, work, medical, and public environments can generate EMI that is strong enough to interfere with the operation of a neurostimulation system or damage system components. Patients should avoid getting too close to these types of EMI sources, which include the following examples: commercial electrical equipment (such as arc welders and induction furnaces), communication equipment (such as microwave transmitters and high-power amateur transmitters), high-voltage power lines, radiofrequency identification (RFID) devices, and some medical procedures (such as therapeutic radiation and electromagnetic lithotripsy).
  • Security, antitheft, and radiofrequency identification (RFID) devices. Some antitheft devices, such as those used at entrances or exits of department stores, libraries, and other public places, and airport security screening devices may affect stimulation. Additionally, RFID devices, which are often used to read identification badges, as well as some tag deactivation devices, such as those used at payment counters at stores and loan desks at libraries, may also affect stimulation. Patients who are implanted with nonadjacent multiple leads and patients who are sensitive to low stimulation thresholds may experience a momentary increase in their perceived stimulation, which some patients have described as uncomfortable or jolting. Patients should cautiously approach such devices and should request help to bypass them. If they must go through a gate or doorway containing this type of device, patients should turn off their IPG and proceed with caution, being sure to move through the device quickly.
  • Wireless use restrictions. In some environments, the use of wireless functions (e.g., Bluetooth® wireless technology) may be restricted. Such restrictions may apply aboard airplanes, in hospitals, near explosives, or in hazardous locations. If you are unsure of the policy that applies to the use of this device, please ask for authorization to use it before turning it on. (Bluetooth® is a registered trademark of Bluetooth SIG, Inc.)
  • Mobile phones. While interference with mobile phones is not anticipated, technology continues to change and interaction between a neurostimulation system and a mobile phone is possible. Advise patients to contact their physician if they are concerned about their mobile phone interacting with their neurostimulation system.

Sterilization and Storage

  • Single-use, sterile device. The implanted components of this neurostimulation system are intended for a single use only. Sterile components in this kit have been sterilized using ethylene oxide (EtO) gas before shipment and are supplied in sterile packaging to permit direct introduction into the sterile field. Do not resterilize or reimplant an explanted system for any reason.
  • Storage environment. Store components and their packaging where they will not come in contact with liquids of any kind.

Handling and Implantation

  • Expiration date. An expiration date (or “use-before” date) is printed on the packaging. Do not use the system if the use-before date has expired.
  • Care and handling of components. Use extreme care when handling system components prior to implantation. Excessive heat, excessive traction, excessive bending, excessive twisting, or the use of sharp instruments may damage and cause failure of the components.
  • Package or component damage. Do not implant a device if the sterile package or components show signs of damage, if the sterile seal is ruptured, or if contamination is suspected for any reason. Return any suspect components to Abbott Medical for evaluation.
  • System testing. To ensure correct operation, always test the system during the implant procedure, before closing the neurostimulator pocket, and before the patient leaves the surgery suite explanted.
  • Device modification. The equipment is not serviceable by the customer. To prevent injury or damage to the system, do not modify the equipment. If needed, return the equipment to Abbott Medical for service.

Hospitals and Medical Environments

  • High-output ultrasonics and lithotripsy. The use of high-output devices, such as an electrohydraulic lithotriptor, may cause damage to the electronic circuitry of an implanted IPG. If lithotripsy must be used, do not focus the energy near the IPG.
  • Ultrasonic scanning equipment. The use of ultrasonic scanning equipment may cause mechanical damage to an implanted neurostimulation system if used directly over the implanted system.
  • External defibrillators. The safety of discharge of an external defibrillator on patients with implanted neurostimulation systems has not been established.
  • Therapeutic radiation. Therapeutic radiation may damage the electronic circuitry of an implanted neurostimulation system, although no testing has been done and no definite information on radiation effects is available. Sources of therapeutic radiation include therapeutic X rays, cobalt machines, and linear accelerators. If radiation therapy is required, the area over the implanted IPG should be shielded with lead. Damage to the system may not be immediately detectable.

ADVERSE EFFECTS
In addition to those risks commonly associated with surgery, the following risks are associated with implanting or using this IPG:

  • Unpleasant sensations or motor disturbances, including involuntary movement, caused by stimulation at high outputs (If either occurs, turn off your IPG immediately.)
  • Stimulation in unwanted places (such as radicular stimulation of the chest wall)
  • Paralysis, weakness, clumsiness, numbness, or pain below the level of the implant
  • Persistent pain at the electrode or IPG site
  • Seroma (mass or swelling) at the IPG site
  • Allergic or rejection response to implant materials
  • Implant migration or skin erosion around the implant
  • Battery failure

Patients without an MR Conditional neurostimulation system should not be subjected to MRI because the electromagnetic field generated by an MRI may damage the device electronics, cause heating at the lead tip that could result in tissue damage, and induce voltage through the lead that could jolt or shock the patient.

Diathermy therapy. Do not use short-wave diathermy, microwave diathermy, or therapeutic ultrasound diathermy (all now referred to as diathermy) on patients implanted with a neurostimulation system. Energy from diathermy can be transferred through the implanted system and cause tissue damage at the location of the implanted electrodes, resulting in severe injury or death.

Diathermy is further prohibited because it may also damage the neurostimulation system components. This damage could result in loss of therapy, requiring additional surgery for system implantation and replacement. Injury or damage can occur during diathermy treatment whether the neurostimulation system is turned on or off. Advise patients to inform their healthcare professional that they should not be exposed to diathermy treatment.

Electrosurgery. To avoid harming the patient or damaging the neurostimulation system, do not use monopolar electrosurgery devices on patients with implanted neurostimulation systems. Before using an electrosurgery device, place the device in Surgery Mode using the patient controller app or clinician programmer app. Confirm the neurostimulation system is functioning correctly after the procedure.

During implant procedures, if electrosurgery devices must be used, take the following actions:

  • Use bipolar electrosurgery only.
  • Complete any electrosurgery procedures before connecting the leads or extensions to the neurostimulator.
  • Keep the current paths from the electrosurgery device as far from the neurostimulation system as possible.
  • Set the electrosurgery device to the lowest possible energy setting.
  • Confirm that the neurostimulation system is functioning correctly during the implant procedure and before closing the neurostimulator pocket

Implanted cardiac systems. Physicians need to be aware of the risk and possible interaction between a neurostimulation system and an implanted cardiac system, such as a pacemaker or defibrillator. Electrical pulses from a neurostimulation system may interact with the sensing operation of an implanted cardiac system, causing the cardiac system to respond inappropriately. To minimize or prevent the implanted cardiac system from sensing the output of the neurostimulation system, (1) maximize the distance between the implanted systems; (2) verify that the neurostimulation system is not interfering with the functions of the implanted cardiac system; and (3) avoid programming either device in a unipolar mode (using the device’s can as an anode) or using neurostimulation system settings that interfere with the function of the implantable cardiac system

Emergency procedures. Instruct patients to designate a representative (family member or close friend) to notify any emergency medical personnel of their implanted neurostimulation system if emergency care is required. Patients will receive an identification card to carry with them that will inform emergency medical personnel of their implanted system. Advise patients to use caution when undergoing any procedure that could include radiofrequency (RF) or microwave ablation, defibrillation, or cardioversion.

Ultrasonic scanning equipment. The use of ultrasonic scanning equipment may cause mechanical damage to an implanted neurostimulation system if used directly over the implanted system.

Therapeutic radiation. Therapeutic radiation may damage the electronic circuitry of an implanted neurostimulation system, although no testing has been done and no definite information on radiation effects is available. Sources of therapeutic radiation include therapeutic X rays, cobalt machines, and linear accelerators. If radiation therapy is required, the area over the implanted IPG should be shielded with lead. Damage to the system may not be immediately detectable.

Restricted areas. Warn patients to seek medical guidance before entering environments that could adversely affect the operation of the implanted device, including areas protected by a warning notice preventing entry by patients fitted with a pacemaker.

Component manipulation by patients. The patient must be instructed to not rub or exert pressure on implanted components through the skin as this may cause lead dislodgement leading to stimulation at the implant site, IPG inversion leading to the inability to communicate with the device, or skin erosion that can lead to another surgical procedure or possible infection.

Lead movement. Patients should be instructed to avoid bending, twisting, stretching, and lifting objects over 2 kg (5 lb) for at least six weeks after implantation. These activities may cause lead movement, resulting in under stimulation or overstimulation for the patient. Excessive lead migration may require reoperation to replace the leads.

Scuba diving and hyperbaric chambers. Instruct patients to avoid scuba diving and entering hyperbaric chambers above 1.5 atmospheres absolute (ATA) because these activities might damage the neurostimulation system.

Operation of machines, equipment, and vehicles. In the clinical experience with this device, patients have experienced few effects when moving from lying down to sitting up. Therefore, it is unlikely patients will need to adjust stimulation when changing positions or moving. However, advise patients who feel uncomfortable paresthesia during postural changes that they should not operate potentially dangerous equipment such as power tools, automobiles, or other motor vehicles. These patients should not climb ladders or participate in activities where postural changes or abrupt movements could alter the perception of stimulation intensity and cause patients to fall or lose control of equipment or vehicles or injure others.

Explosive and flammable gases. Do not use a clinician programmer or patient controller in an environment where explosive or flammable gas fumes or vapors are present. The operation of these devices could cause them to ignite, causing severe burns, injury, or death.

Keep the device dry. Programmer and controller devices are not waterproof. Keep them dry to avoid damage. Advise patients to not use their device when engaging in activities that might cause it to get wet, such as swimming or bathing.

Device components. The use of components not approved for use by Abbott Medical with this system may result in damage to the system and increased risk to the patient.

Device modification. The equipment is not serviceable by the customer. To prevent injury or damage to the system, do not modify the equipment. If needed, return the equipment to Abbott Medical for service.

Application modification. To prevent unintended stimulation, do not modify the operating system in any way. Do not use the application if the operating system is compromised (i.e., jailbroken).

Case damage. Do not handle the IPG if the case is pierced or ruptured because severe burns could result from exposure to battery chemicals.

IPG disposal. Return all explanted IPGs to Abbott Medical for safe disposal. IPGs contain batteries as well as other potentially hazardous materials. Do not crush, puncture, or burn the IPG because explosion or fire may result.

Product materials. Neurostimulation systems have materials that come in contact or may come in contact with tissue. A physician should determine whether or not a patient may have an allergic reaction to these materials before the system is implanted.

PRECAUTIONS
The following precautions apply to this neurostimulation system.

General Precautions

  • Clinician training. Implanting physicians should be experienced in the diagnosis and treatment of chronic pain syndromes and have undergone surgical and device implantation training.
  • Patient selection. It is extremely important to select patients appropriately for neurostimulation. Thorough psychiatric screening should be performed. Patients should not be dependent on drugs and should be able to operate the neurostimulation system.
  • Infection. Follow proper infection control procedures. Infections related to system implantation might require that the device be explanted.
  • Implantation of multiple leads. If multiple leads or extensions are implanted, the leads and extensions should be routed in close proximity. Nonadjacent leads and extensions have the possibility of creating a conduit for stray electromagnetic energy that could cause the patient unwanted stimulation.
  • High stimulation outputs. Stimulation at high outputs may cause unpleasant sensations or motor disturbances, or render the patient incapable of controlling the stimulator. If unpleasant sensations occur, the device should be turned off immediately.
  • Postural changes. In the clinical experience with this device, patients have experienced few effects when moving from lying down to sitting up. Therefore, it is unlikely patients will need to adjust stimulation when changing positions or moving. However, some patients may experience a decrease or increase in the perceived level of stimulation. Perception of higher levels of stimulation has been described by some patients as uncomfortable, painful, or jolting. Advise patients who experience these types of stimulation changes to turn down the amplitude or turn off the IPG before making extreme posture changes or abrupt movements such as stretching, lifting their arms over their heads, or exercising. If unpleasant sensations occur, the IPG should be turned off immediately.

Sterilization and Storage

  • Single-use, sterile device. The implanted components of this neurostimulation system are intended for a single use only. Sterile components in this kit have been sterilized using ethylene oxide (EtO) gas before shipment and are supplied in sterile packaging to permit direct introduction into the sterile field. Do not resterilize or reimplant an explanted system for any reason.
  • Storage environment. Store components and their packaging where they will not come in contact with liquids of any kind.

Handling and Implementation

  • Expiration date. An expiration date (or “use-before” date) is printed on the packaging. Do not use the system if the use-before date has expired.
  • Package or component damage. Before opening any sterile package, verify the kit model number, that the kit is within its expiration (use-before) date, and that the packaging has not been damaged or compromised in any way. If the packaging has been compromised, the device is beyond its expiration date, or the sterile package or device show signs of damage, do not use the device as it may be compromised and could cause harm to the patient. Return any suspect components to Abbott Medical for evaluation.
  • Handle the device with care. The clinician programmer and patient controller are sensitive electronic devices that can be damaged by rough handling, such as dropping them on the ground.
  • Lead inspection. Carefully inspect the lead (in the sterile field) for damage after removing it from the sterile package. Damage to the lead body can cause improper function and stimulation or stimulation to areas other than the intended target.
  • Care and handling of components. Use extreme care when handling system components prior to implantation. Excessive heat, excessive traction, excessive bending, excessive twisting, or the use of sharp instruments may damage and cause failure of the components.
  • Component handling. Do not bend, kink, or stretch the lead body, sheaths, or other components as this may result in damage to the component and poor function.
  • Using surgical instruments. Do not use surgical instruments to handle the lead. The force of the instruments may damage the lead or stylet.
  • Component manipulation. Do not over-manipulate the sheath and lead system as this may result in trauma within the epidural space.
  • Stylet handling. Do not bend, kink, or use surgical instruments on the stylet, as this may damage it. Use care when reinserting a stylet. Too much pressure on the stylet could damage the lead, resulting in intermittent or loss of stimulation. Remove the stylet from the lead only when satisfied with lead placement. If the stylet is removed from the lead, it may be difficult to reinsert it.
  • Sheath insertion precaution. Do not insert the sheath into the epidural space without the lead or guidewire inserted, as this may cause injury to the dura.
  • Stabilizing the lead during insertion. When inserting the lead-sheath assembly through the needle into the epidural space, tighten the lead stabilizer to prevent lead migration out of the sheath. Failure to do so may cause harm to the patient such as damage to the dura.
  • Bending the sheath. Do not bend the sheath without the lead inside the sheath, as this will permanently kink it and make it difficult to deploy the lead.
  • Lead handling. If the operating field is bloody, wipe gloves, lead, stylet, and sheath before handling the lead. Failure to do so may result in difficulty delivering the lead.
  • Exposure to body fluids or saline. Prior to connection, exposure of the metal contacts, such as those on the connection end of a lead or extension, to body fluids or saline can lead to corrosion. If such exposure occurs, clean the affected parts with sterile, deionized water or sterile water for irrigation, and dry them completely prior to lead connection and implantation.
  • System testing. To ensure correct operation, always test the system during the implant procedure, before closing the neurostimulator pocket, and before the patient leaves the surgery suite.
  • Component disposal. Return all explanted components to Abbott Medical for safe disposal.

Hospital and Medical Environments

  • High-output ultrasonics and lithotripsy. The use of high-output devices, such as an electrohydraulic lithotriptor, may cause damage to the electronic circuitry of an implanted IPG. If lithotripsy must be used, do not focus the energy near the IPG.

Home and Occupational Environments

  • Electromagnetic interference (EMI). Some equipment in home, work, medical, and public environments can generate EMI that is strong enough to interfere with the operation of a neurostimulation system or damage system components. Patients should avoid getting too close to these types of EMI sources, which include the following examples: commercial electrical equipment (such as arc welders and induction furnaces), communication equipment (such as microwave transmitters and high-power amateur transmitters), high-voltage power lines, radiofrequency identification (RFID) devices, some medical procedures (such as therapeutic radiation, static magnetic field [SMF] therapy, and electromagnetic lithotripsy), and some medical devices (such as bone growth stimulators, transcutaneous electrical nerve stimulation [TENS] devices, dental drills, and ultrasonic probes).
  • Wireless use restrictions. In some environments, the use of wireless functions (e.g., Bluetooth® wireless technology) may be restricted. Such restrictions may apply aboard airplanes, in hospitals, near explosives, or in hazardous locations. If you are unsure of the policy that applies to the use of this device, please ask for authorization to use it before turning it on. (Bluetooth® is a registered trademark of Bluetooth SIG, Inc.)
  • Security, antitheft, and radiofrequency identification (RFID) devices. Some antitheft devices, such as those used at entrances or exits of department stores, libraries, and other public places, and airport security screening devices may affect stimulation. Additionally, RFID devices, which are often used to read identification badges, as well as some tag deactivation devices, such as those used at payment counters at stores and loan desks at libraries, may also affect stimulation. Patients who are implanted with nonadjacent multiple leads and patients who are sensitive to low stimulation thresholds may experience a momentary increase in their perceived stimulation, which some patients have described as uncomfortable or jolting. Patients should cautiously approach such devices and should request help to bypass them. If they must go through a gate or doorway containing this type of device, patients should turn off their IPG and proceed with caution, being sure to move through the device quickly.
  • Mobile phones. While interference with mobile phones is not anticipated, technology continues to change and interaction between a neurostimulation system and a mobile phone is possible. Advise patients to contact their physician if they are concerned about their mobile phone interacting with their neurostimulation system.

ADVERSE EFFECTS
In addition to those risks commonly associated with surgery, the following risks are associated with using this neurostimulation system:

  • Unpleasant sensations or motor disturbances, including involuntary movement, caused by stimulation at high outputs (if either occurs, turn off your IPG immediately.)
  • Undesirable changes in stimulation, which may be related to cellular changes in tissue around the electrodes, changes in electrode position, loose electrical connections, or lead failure or breakage
  • Stimulation in unwanted places (such as stimulation of the chest wall)
  • Lead migration, causing changes in stimulation or reduced pain relief
  • Epidural hemorrhage, hematoma, infection, spinal cord compression, or paralysis from placement of a lead in the epidural space
  • Cerebrospinal fluid (CSF) leakage
  • Tissue damage or nerve damage
  • Paralysis, weakness, clumsiness, numbness, sensory loss, or pain below the level of the implant
  • Pain or bleeding where the needle was inserted
  • Persistent pain at the electrode or IPG site
  • Escalating pain
  • Seroma (mass or swelling) at the implant site
  • Headache
  • Allergic or rejection response to device or implant materials
  • Implant migration or skin erosion around the implant
  • Battery failure, leakage, or both
  • Hardware malfunction that requires replacing the neurostimulator
  • Pain from a noninjurious stimulus to the skin or an exaggerated sense of pain

Additional risks to the patients, as a result of the placement and stimulation of the lead in the area of the dorsal root ganglion (DRG), include pain from setting the stimulation parameters too high. This may occur once the lead is in place and is connected to the neurostimulator and activated. The neurostimulator is controlled by a trained operator and the starting point for the stimulation will be set to the lowest available settings. Additionally, all patients will be awake and conversant during the procedure to minimize the impact.
