Masters 15mm pediatric heart valve

INDICATIONS FOR USE

The SJM™ Masters Series Mechanical Heart Valve is intended for use as a replacement valve in patients with a diseased, damaged, or malfunctioning mitral or aortic heart valve. This device may also be used to replace a previously implanted mitral or aortic prosthetic heart valve. The sizer model 905-15 is indicated to confirm size selection of the 15AHPJ-505 and 15MHPJ-505 valves.

CONTRAINDICATIONS

The SJM™ Masters Series Mechanical Heart Valve is contraindicated for individuals unable to tolerate anticoagulation therapy. The sizer model 905-15 is contraindicated for use with any devices other than the 15 AHPJ-505 and 15MHPJ-505 valves. Any sizer sterilization method other than steam is contraindicated.

WARNINGS

Valve

  • For single use only. Attempts to reuse the valve may result in valve malfunction, inadequate sterilization, or patient harm.
  • Use only St. Jude Medical™ mechanical heart valve sizers.
  • Do not use if:
    • The valve has been dropped, damaged, or mishandled in anyway.
    • The expiration date has elapsed.
    • The tamper-evident container seal or inner/ outer tray seals are damaged, broken, or missing.
  • Remove any residual tissue that may impair valve size selection, correct seating of the valve, rotation of the valve, or leaflet motion.
  • Proper valve size selection is crucial. Do not oversize the valve. If the native annulus measurement falls between two SJM™ Masters Series Mechanical Heart Valve sizes, use the smaller prosthetic valve size.
  • The outer tray is not sterile, and should not be placed in the sterile field.
  • To minimize direct handling of the valve during implantation, do not remove the holder/rotator until the valve has been seated in the annulus.
  • Do not use hard or rigid instruments to test leaflet mobility, as this may result in structural damage to the valve or thromboembolic complications. Use a St. Jude Medical™ leaflet tester to gently test valve leaflet mobility.
  • Place sutures in the outer half of the valve sewing cuff.
  • Never apply force to the valve leaflets. Force may cause structural damage to the valve.
  • Use only SJM™ Valve Holder/Rotators to perform valve rotation. Use of other instruments could result in structural damage. The valve holder/rotator is intended for single use only and should be discarded after surgery.
  • The two retention sutures on the valve holder/ rotator must be cut and removed before the valve can be rotated.
  • Do not pass catheters or other instruments through St. Jude Medical™ mechanical heart valves. This could result in scratched or damaged valve components, leaflet fracture, or dislodgment.
  • Cut suture ends short, especially in the vicinity of the pivot guards, to prevent leaflet impingement.

PRECAUTIONS

Valve

  • Do not touch the prosthetic valve unnecessarily, even with gloved hands. This may cause scratches or surface imperfections that may lead to thrombus formation.
  • Be careful not to cut or tear the valve sewing cuff when removing the identification tag and the holder/rotator from the valve.
  • Before placing sutures in the valve sewing cuff, verify that the valve is mounted correctly on the valve holder/rotator.
  • To avoid structural damage, the valve must be rotated in the fully open position.
  • To minimize rotational torque, verify that the valve holder/rotator is properly seated in the valve, and that the valve holder handle is perpendicular to the valve.
  • Remove any loose suture or thread, which may be a source of thrombus or thromboembolism.
  • Implantation of a prosthetic valve too large for the annulus may result in increased risk of damage to the conductive system, obstruction of the left ventricular outflow tract, impairment of valve mobility, damage to the left circumflex artery, and damage to surrounding tissues or cardiac structures including obstruction and/or distortion of adjacent cardiac structures.
  • NOTE: PROSPECTIVE DATA TO SUPPORT SAFETY AND EFFECTIVENESS OF THE 15-mm HP VALVE IMPLANTED IN THE AORTIC POSITION ARE NOT CURRENTLY AVAILABLE.

Sizer

  • Instruments must be cleaned and sterilized prior to use.
  • Do not use cracked, deformed, discolored/rusted, or damaged instruments.
  • Improper cleaning may result in an immunological or toxic reaction.
  • Instrument sterilization temperature must not exceed 280°F (138°C).
  • Do not bend flexible instrument handles beyond a 90° angle.
  • Instruments must be sterilized in a tray or container that is permeable to steam.
  • Do not expose instruments to cleaning or rinse agents that are not compatible with polysulfone or polyphenylsulfone.

POTENTIAL ADVERSE EVENTS

Complications associated with replacement mechanical heart valves include, but are not limited to, hemolysis, infections, thrombus, or thromboembolism, valve dehiscence, unacceptable hemodynamic performance, hemorrhagic complications secondary to anticoagulation therapy, heart block requiring pacemaker implant, prosthetic failure, adjacent cardiac structure interference, heart failure, stroke, myocardial infarction, or death. Any of these complications may require reoperation or explantation of the device.

MitraClip

Risks, Warnings, and Precautions

What Are the Possible Risks 1 Year After the Procedure?

The most common serious risks observed within 1 year of the MitraClip procedure in patients enrolled in the PR DMR Cohort include:

  • Death from any cause occurred in 30 out of 127 patients (23.6%)
  • Stroke occurred in 3 out of 127 patients (2.4%). Stroke is a condition where lack of blood flow to the brain causes rapid loss of brain function
  • Ventilation longer than 48 hours occurred in 6 out of 127 patients (4.7%). This means that the use of a ventilator was required more than two days to help a patient breathe
  • Major vascular complications occurred in 9 out of 127 patients (7.1%). Examples include a hematoma (large blood clot under the skin) or damage to the artery and surrounding veins where the catheter was inserted that requires surgical repair
  • Bleeding events occurred in 25 out of 127 patients (19.7%). This refers to a loss of blood related to the procedure that required blood transfusion of 2 or more unit
  • Kidney failure occurred in 5 out of 127 patients (3.9%)
  • Gastrointestinal complications occurred in 3 out of 127 patients (2.4%)
  • Septicemia occurred in 6 out of 127 patients (4.7%). Septicemia is a serious infection of the blood often caused by bacteria

Warnings

  • MitraClip therapy should only be used in patients with significant, symptomatic, degenerative mitral regurgitation who are too sick for mitral valve surgery.
  • MitraClip therapy is intended to reduce mitral regurgitation. If mitral regurgitation is not reduced enough, you may not get the full treatment benefits of reduced hospitalizations and improvement in heart failure symptoms and quality of life expected from MitraClip therapy.

Precautions

  • MitraClip therapy should only be used in patients considered to be too sick for surgery. This is determined by the clinical judgment of a heart team, including a cardiac surgeon experienced in mitral valve surgery and a cardiologist experienced in mitral valve disease, based on the presence of one or more surgical risk factors.
  • The major clinical benefits of MitraClip therapy are reduction of mitral regurgitation, resulting in reduced hospitalizations and improvement in heart failure symptoms and quality of life. No benefit on how long a patient survives following MitraClip therapy has been demonstrated. How long the MitraClip device will last is unknown at this time.
  • The first MitraClip device was implanted in 2003 and laboratory testing supports durability of the device over a period of 15 years. Regular medical follow-up is essential to evaluate how the MitraClip device is performing. Notify your doctor immediately if you experience the return of any symptoms related to mitral regurgitation.
  • Patients who have undergone MitraClip therapy should receive prophylactic antibiotic therapy before any medical or dental procedure to minimize the possibility of infection.
  • The safety and effectiveness of MitraClip therapy have not been established in patients who have functional (also called secondary) mitral regurgitation.
  • The safety and effectiveness of MitraClip therapy have not been established in patients who have specific mitral valve anatomy that may interfere with proper placement and positioning of the MitraClip device:
    • A mitral valve opening that is too small
    • Calcified mitral valve leaflets
    • A cleft of the mitral valve leaflet
    • A leaflet flail width or leaflet flail gap that is too large
  • MitraClip therapy has not been tested in pregnant women or children or infants, and the device may not work for these patients.

Proclaim Elite Recharge-Free SCS System

Proclaim™ Elite IPG with BurstDR™ Stimulation

3660,3662

*BurstDR™ stimulation, patented technology exclusively from St. Jude Medical, is also referred to as Burst stimulation in clinical literature.

Rx Only

Brief Summary: Prior to using these devices, please review the Instructions for Use for a complete listing of indications, contraindications, warnings, precautions, potential adverse events and directions for use.

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.

Contraindications: 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 St. Jude Medical product information page at sjmprofessional.com/MRI.

Warnings

The following warnings apply to these components.

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 St. Jude 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 systemimplantation and replacement. Injury or damage can occur during diathermy treatment whether the neurostimulation system is turned on or off.

Electrosurgery devices.Electrosurgery devices should not be used in close proximity to an implanted neurostimulation system. Contact between an active electrode and an implanted IPG, lead, or extension can cause severe injury to thepatient. If use of electrocautery is necessary, first turn off the neurostimulation system.

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.

Operation of machines, equipment, and vehicles. Patients using therapy that generates paresthesia should turn off stimulation before operating motorized vehicles, such as automobiles, or potentially dangerous machinery and equipment because sudden stimulation changes may distract them from properly operating it. However, current data shows that most patients using BurstDR™ stimulation therapy do not experience paresthesia. For patients who do not feel paresthesia, sudden stimulation changes are less likely to occur and distract them while operating motorized vehicles, machinery, or equipment.

Burst stimulation during the trial period. The use of BurstDR stimulation during the trial period has not been evaluated for effectiveness.

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 St. Jude Medical 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 St. Jude 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 these components.

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. Patients should avoid getting too closeto 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, and some medical procedures (such as therapeutic radiation and electromagnetic lithotripsy).

Theft detectors and metal screening devices. Certain types ofantitheft devices, such as those used atentrances or exits of department stores, libraries, and other public establishments, and airport security screening devices may 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 has been described by some patients as uncomfortable or jolting. Patients should use caution when approaching such a device and should request assistance to bypass the device. If they must proceed through the device, patients should turn off the IPG and proceed with caution, being sure to move through the detector 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. The effect of mobile phones on neurostimulation systems is unknown; patients should avoid placing mobile phones directly over the 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 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.

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 St. Jude Medical for evaluation.

System testing. To ensure correct operation, the system should always be tested after implantation and before the patient leaves the surgery suite.

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 St. Jude Medical for service.

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.

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
  • Paralysis, weakness, clumsiness, numbness, or pain below the level of the implant
  • Persistent pain at the 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
  •
