2. INDICATIONS 2. INDICATIONSPLATINIUM VR is indicated for use in patients who are at high risk of sudden cardiac death due to ventricular tachyarrhythmias and who have experienced one of the following situations:─Survival of at least one episode of cardiac arrest (manifested by the loss of consciousness) due to ventricular tachyarrhythmia,─Recurrent, poorly tolerated sustained ventricular tachycardia (VT).6SORIN – PLATINIUM VR – U461ANOTE: The clinical outcome for hemodynamically stable VT patients is not fully known. Safety and effectiveness studies have not been conducted.
3. CONTRAINDICATIONS 3. CONTRAINDICATIONSImplantation of PLATINIUM VR is contraindicated in patients:─whose ventricular tachyarrhythmias may have transient or reversible causes such as: acute myocardial infarction, digitalis intoxication, drowning, electrocution, electrolyte imbalance, hypoxia, sepsis, or unstable ischemic episodes,─who present incessant tachyarrhythmia,─who have an internal pacemaker,─whose primary disorder is bradyarrhythmias, or atrial tachyarrhythmias.SORIN – PLATINIUM VR – U461A 7
4. WARNINGS AND PRECAUTIONS 4. WARNINGS AND PRECAUTIONSThe patient should be warned of the potential risks of defibrillator malfunction if he is exposed to external magnetic, electrical, or electromagnetic signals.These potential interference sources may cause conversion to inhibited mode (because of noise detection), erratic delivery of VT or VF therapies, nominal programming, or much more rarely, irreversible damage to the device’s circuits.The main sources of high magnitude disturbance are: powerful radiofrequency equipment (radar), industrial motors and transformers, induction furnaces, resistance, arc-welding equipment and high power loudspeakers.Electrical Isolation:Do not permit the patient to contact grounded equipment that could produce hazardous leakage current. Ensuing arrhythmia induction could result in the patient’s death.Antitheft gates:Since antitheft devices at the entrance to stores are not subject to any safety standards, it is advisable to spend as little time as possible in their vicinity.Airport detection systems:Since airport detection systems are not subject to any safety standards, it is advisable to spend as little time as possible in their vicinity.Work environment:The patient's work environment may be an important source of disturbance. In that case, specific recommendations may be required.High voltage power transmission lines:High voltage power transmission lines may generate enough disturbance to interfere with defibrillator operation if approached too closely.Communication equipment:Communication equipment such as microwave transmitters, linear power amplifiers, or high-power amateur transmitters may generate enough disturbance to interfere with defibrillator operation if approached too closely.Home appliances:Home appliances that are in good working order and properly grounded do not usually produce enough disturbance to interfere with defibrillator operation. However, there are reports of device interferences caused by electric hand tools or electric razors used directly over the device implant site. Patient should also avoid using induction ovens and cookers.8SORIN – PLATINIUM VR – U461ACAUTION: Do not tap sharply on the ICD can after implant, because the ICD's sensing circuits can detect this as R-waves, and such oversensing could result in inappropriate pacing, inhibition, or therapy. Normal activities after implant do not result in such oversensing.
4. WARNINGS AND PRECAUTIONS4.1. RISKS RELATED TO MEDICAL ENVIRONMENTIt is advisable to carefully monitor defibrillator operation prior to and after any medical treatment during which an electrical current from an external source passes through the patient's body.Magnetic Resonance Imaging:MRI is strictly contraindicated in cardiac defibrillator patients.Radiofrequency ablation:A radiofrequency ablation procedure in a patient with a generator may cause device malfunction or damage. RF ablation risks may be minimized by:1. Programming Shock Therapy and ATP to OFF.2. Avoiding direct contact between the ablation catheter and the implanted lead or generator.3. Positioning the ground, placing it so that the current pathway does not pass through or near the device, i.e. place the ground plate under the patient’s buttocks or legs.4. Having external defibrillation equipment available.Electrocautery or diathermy device:Diathermy and electrocautery equipment should not be used. If such devices must be used:1. Keep the current path and ground plate as far away from the device and the lead as possible (a minimum of 15 cm [six inches]). 2. Before procedure, deactivate ATP and shock therapies.3. During the procedure, keep the electrocautery device as far as possible from the cardiac defibrillator. Set it at minimum intensity. Use it briefly.4. After the procedure, check for proper implant function. The device should never be exposed directly to the diathermy source.External defibrillation:PLATINIUM VR is protected from external defibrillation shocks.1. Before external defibrillation, deactivate ATP and shock therapies.2. During external defibrillation, it is advisable to avoid placing the defibrillating paddles directly over the casing or over the lead. The defibrillating paddles should preferably be placed in an anteroposterior position.3. Avoid any direct contact between the defibrillation paddles and the conductive parts of the implanted leads or casing of the implanted device.4. After external defibrillation, check for proper device function.Radiation therapy:Avoid exposure to ionizing radiation. Betatrons are contraindicated. If high doses of radiation therapy cannot be avoided, the defibrillator should be protected from direct exposure with a protection shield. ATP and shock therapies should be disabled during exposure and proper device function should be checked regularly afterwards. Resulting damage may not be immediately detectable. If irradiation of tissues close to the implantation site is necessary, it is recommended that the cardiac defibrillator be moved. As a safety measure, an external defibrillator should be immediately available.Lithotripsy:Lithotripsy may permanently damage the device if it is at the focal point of the lithotripsy beam. If lithotripsy must be used, keep the defibrillator at least 2.5 to 5 cm (1-2 inches) away from the focal point of the lithotripsy beam.SORIN – PLATINIUM VR – U461A 9
4. WARNINGS AND PRECAUTIONSDiagnostic ultrasound (echography):The defibrillator is not affected by ultrasound imaging devices.Scales with body fat monitors and electronic muscle stimulators:A patient with an implanted PLATINIUM VR should not use these devices.4.2. STERILIZATION, STORAGE AND HANDLINGResterilization:Do not resterilize and re-implant explanted ICDs."Use Before" Date:A "Use Before" date is printed on the outer storage package and on the sterile package. Do not implant the device after this date because the battery may have reduced longevity and sterility may be affected. It should be returned to Sorin.If Package is damaged:Do not use the device or accessories if the packaging is wet, punctured, opened or damaged because the integrity of the sterile packaging may be compromised. Return the device to the manufacturer.Device Storage:Store the device in a clean area, away from magnets, kits containing magnets, and sources of electromagnetic disturbance to avoid device damage. Store the device between 0 - 50 °C (32 - 122 °F). Temperatures outside the specified range may damage the device.Equilibration:Allow the device to reach room temperature before programming or implanting the device because rapid temperature changes may affect initial device function.4.3. IMPLANTATION AND DEVICE PROGRAMMINGUse only a Sorin programmer to communicate with the device.Do not inadvertently position any magnet over the ICD; this suspends tachyarrhythmia detection and treatment.Replace the device when the RRT (Recommended Replacement Time*) point (defined by a battery voltage of 2.66 ± 0.01 V or a magnet rate lower than or equal to 80 bpm) is reached.Program device parameters such as sensitivity threshold and VT and VF detection intervals as specified in the device manuals.Lead System:Do not use a lead system other than those with demonstrated compatibility because undersensing cardiac activity and failure to deliver necessary therapy may result.In situations where an ICD and a pacemaker are implanted in the same patient, interaction testing should be completed. If the interaction between the ICD and the pacemaker cannot be resolved through repositioning of the leads or reprogramming of either the pacemaker or the ICD, the pacemaker should not be implanted (or should be explanted if previously implanted).Failure to properly insert the torque screwdriver into the perforation at an angle perpendicular to the connector receptacle may result in damage to the sealing system and its self-sealing properties.10 SORIN – PLATINIUM VR – U461A
4. WARNINGS AND PRECAUTIONSIn the event of a warning on a low shock impedance, and after lead replacement or reconnection: it is recommended to check the system integrity (sensing and pacing thresholds and the impedance of the shock electrodes)It is recommended that a security margin of at least 10 J be demonstrated between the effective shock energy and maximum programmable energy. Carefully confirm that true ventricular fibrillation has been induced because the DFT for ventricular tachycardia or flutter may be lower.The defibrillator should be implanted with the engraved side facing outwards in order to facilitate telemetric communication with the programming head and to display the radiographic identification correctly.*: corresponds to ERI (Elective Replacement Indicator) previously used. 4.4. LEAD EVALUATION AND LEAD CONNECTIONPLATINIUM VR 1210 has two DF-1 and one IS-1 connector ports.PLATINIUM VR 1240 has one DF4 connector port.IS-1 refers to the international standard whereby leads and generators from different manufacturers are assured a basic fit (ISO 5841-1:2000).DF-1 refers to the international standard for defibrillation lead connectors (ISO 11318:2002).DF4 refers to the international standard for defibrillation lead connectors (ISO 27186:2010).Use only DF4-LLHH or DF4-LLHO standard lead connector types according to ISO 27186: 2010.Do not tie a ligature directly to the lead body, tie it too tightly, or otherwise create excessive strain at the insertion site as this may damage the lead. Use the lead stabilizer to secure the lead lateral to the venous entry site.Do not immerse the lead in mineral oil, silicone oil, or any other liquid.Do not grip the lead with surgical instruments.Do not use excessive force or surgical instruments to insert a stylet into a lead.Use ventricular transvenous leads with caution in patients with either a mechanical or bioprosthetic tricuspid valvular prosthesis.Use the correct suture sleeve (when needed), to immobilize the lead and protect it against damage from ligatures.Never implant the system with a lead system that has a measured shock impedance of less than 30 ohms. A protection circuit in the defibrillator prevents shock delivery when impedance is too low. If the shock impedance is less than 30 ohms, reposition the lead system to allow a greater distance between the electrodes.Do not kink leads. Kinking leads may cause additional stress on the leads, possibly resulting in lead fracture.Do not insert a lead connector pin into the connector block without first visually verifying that the setscrews are sufficiently retracted. Do not tighten the setscrews unless a lead connector pin is inserted because it could damage the connector block.Lead electrodes in contact during a cardioversion or defibrillation therapy will cause current to bypass the heart, possibly damaging the ICD and the lead. While the ICD is connected to the lead, make sure that the metal portions of any electrodes do not touch each other.If a pacing lead is abandoned rather than removed, it must be capped to ensure that it is not a pathway for currents to or from the heart.If a thoracotomy is required to place epicardial patches, it should be done during a separate procedure to reduce the risk of morbidity and mortality.SORIN – PLATINIUM VR – U461A 11
4. WARNINGS AND PRECAUTIONSDo not place the patch lead over nerve tissue as this may cause nerve damage.Place the patch lead with the conducting coil side facing the heart to ensure delivery of energy to the heart.Place the sutures well outside the coil of the patch lead or in the area between the coils to avoid possible coil fracture.If countershock is unsuccessful using external paddles, adjust the external paddle position (e.g., anterior-lateral to anterior-posterior) and be sure that the external paddle is not positioned over the patch.Do not fold, alter, or remove any portion of the patch as it may compromise electrode function or longevity.If a header port is unused on the generator, the port must be plugged to protect the generator.4.5. GENERATOR EXPLANT AND DISPOSALInterrogate the device, and program shock therapy off prior to explanting, cleaning or shipping the device to prevent unwanted shocks.Return all explanted generators and leads to the manufacturer.Never incinerate the device due to the potential for explosion. The device must be explanted before cremation.12 SORIN – PLATINIUM VR – U461A
5. ADVERSE EVENTS 5. ADVERSE EVENTSClinical data presented in this section are from the Defender study.PLATINIUM VR is similar in design and function to the Defender devices.The data provided are applicable to PLATINIUM VR.5.1. DEFENDER STUDYClinical study of Defender IV DR 612 included 60 devices implanted in 60 patients, 38 in Europe (37 patients followed for a minimum of 3 months), and 22 in the U.S. (IDE G970282/S15) with a total device exposure of 228.7 and 30.3 device months, respectively. No deaths, serious adverse experiences or complications were judged to be device-related, as determined by the investigator. The following tables summarize the safety data for this study.There was 1 death in the study that was classified as arrhythmic. The cause of death was recurrent VT/VF which occurred 19 days post implant.In the following tables, complications are defined as adverse device effect, which cannot be treated or resolved by simple adjustments (e.g. reprogramming) and requires intervention.Observations are defined as symptomatic or asymptomatic clinical events with potential adverse device effects that do not require intervention or can be corrected by simple adjustments.Two of the 38 Defender IV DR 612 patients in Europe (37 patients followed for a minimum of 3 months) experienced a total of three complications, including device failures and replacements. Fourteen of the 38 Defender IV DR 612 patients experienced a total of 18 observations. Complications and observations are reported in Tables 1 and 2. It should be noted that a patient can have more than one observation or complication.

6. CLINICAL STUDIES 6. CLINICAL STUDIESClinical data presented in this section are from the Defender study.PLATINIUM VR is similar in design and function to the Defender devices.The data provided are applicable to PLATINIUM VR.6.1. DEFENDER STUDYObjectives:The primary objectives of this study were to demonstrate a complication free rate (CFR) comparable to that of historical controls, to demonstrate, using a chronotropic assessment exercise protocol (CAEP), a rate response proportional to and appropriate for the level of exercise, and to evaluate and report the incidence of adverse events.Materials:Each patient received one Defender IV DR 612 defibrillator, an atrial pacing and sensing lead, and a Medtronic, Angeion, or Biotronik defibrillation lead in the U.S. or any commercially available defibrillator lead outside the U.S.Methods:Investigators selected patients who survived at least one episode of cardiac arrest (manifested by loss of consciousness) presumably due to a ventricular tachyarrhythmia or exhibited recurrent, poorly tolerated, sustained ventricular tachycardia (VT). The protocol required evaluation of performance and adverse events at pre-discharge, one month, three months, six months, and (in the U.S.) every three months thereafter. At the one-month visit, eligible patients performed a chronotropic assessment exercise protocol (CAEP) maximal exercise test.Study Population.The table below summarizes inclusions.Region Date of first implantDate of last implantData cut-off dateNumber of centersNumber of patientsUS 14-Dec-99 08-Mar-00 14-Mar-00 6 22Europe 04-May-99 26-Jul-99 14-Apr-00 11 38All 04-May-99 08-Mar-00 14-Apr-00 (Eur), 14-Mar-00 (US)17 606.1.1.

7. PATIENT SELECTION AND TREATMENT 7. PATIENT SELECTION AND TREATMENT7.1. INDIVIDUALIZATION OF TREATMENTExercise stress testing:If the patient’s condition permits, use exercise stress testing to:─Determine the maximum rate of the patient’s normal rhythm,─Identify any supraventricular tachyarrhythmias,─Identify exercise-induced tachyarrhythmias.The maximum exercise rate or the presence of supraventricular tachyarrhythmias may influence selection of programmable parameters. Holter monitoring or other extended ECG monitoring also may be helpful.Electrophysiologic (EP) testing:EP testing may be useful for ICD candidates.EP testing may identify the classifications and rates of all the ventricular and atrial arrhythmias, whether spontaneous or during EP testing.Drug resistant supraventricular tachyarrhythmias (SVTs):Drug resistant supraventricular tachyarrhythmias (SVTs) may initiate frequent unwanted device therapy.A careful choice of programming options is necessary for such patients.Antiarrhythmic drug therapy:If the patient is being treated with antiarrhythmic or cardiac drugs, the patient should be on a maintenance drug dose rather than a loading dose at the time of ICD implantation. If changes to drug therapy are made, repeated arrhythmia inductions are recommended to verify ICD detection and conversion. The ICD also may need to be reprogrammed.Changes in a patient’s antiarrhythmic drug or any other medication that affects the patient’s normal cardiac rate or conduction can affect the rate of tachyarrhythmias and/or efficacy of therapy.Direct any questions regarding the individualization of patient therapy to Sorin’s representative.18 SORIN – PLATINIUM VR – U461ACAUTION: To avoid inappropriate therapy during an exercise stress test, do not reprogram any parameter during the test. When a parameter is reprogrammed, algorithm forces acceleration to "ventricular". During conducted sinus tachycardia within the programmed Tachy zone, the device detects a 1:1 fast rhythm. Assuming that acceleration was set to ventricular by reprogramming, the device may identify this as a VT, and may immediately apply the corresponding therapy.
7. PATIENT SELECTION AND TREATMENT7.2. SPECIFIC PATIENT POPULATIONSPregnancy:If there is a need to image the device, care should be taken to minimize radiation exposure to the foetus and the mother.Nursing Mothers:Although appropriate biocompatibility testing has been conducted for this implant device, there has been no quantitative assessment of the presence of leachables in breast milk.Pediatric Patients:This device has not been studied in patients younger than 18 years of age.Geriatric Patients:Most of the patients receiving this device in clinical studies were over the age of 60 years.Handicapped and Disabled Patients:Special care is needed in using this device for patients using an electrical wheel chair or other electrical (external or implanted) devices.SORIN – PLATINIUM VR – U461A 19
8. PATIENT COUNSELLING INFORMATION 8. PATIENT COUNSELLING INFORMATIONThe physician should consider the following points in counselling the patient about this device:─Persons administering CPR may experience tingling on the patient’s body surface when the patient’s ICD system delivers a shock.─Advise patients to carry Sorin ID cards and/or ID bracelets documenting their ICD system.20 SORIN – PLATINIUM VR – U461A

13. DEVICE DESCRIPTION 13. DEVICE DESCRIPTIONThe PLATINIUM VR ICD device and programming system. The programming system includes the Sorin dedicated programmer with the SMARTVIEW programming software connected to a CPR3 programming head. The programming system is configured and furnished by Sorin.The PLATINIUM VR can serve as a defibrillation electrode (active housing) with a total surface area of 63 cm².The PLATINIUM VR is designed to recognize and treat slow or fast VT and VF by continuously monitoring ventricular activity to identify persistent ventricular arrhythmias and to deliver appropriate therapies. PLATINIUM VR features DISCRIMINATION algorithm, which is specifically designed to differentiate ventricular tachycardias from fast rhythms of supraventricular origin. DISCRIMINATION continuously monitors R-R interval stability, searches for long cycles and evaluates sudden onset.In addition to the advanced detection scheme, PLATINIUM VR offers programmable single-chamber pacing therapy with or without rate-responsive capabilities using an acceleration sensor.PLATINIUM VR offers tiered therapy. Therapies can be programmed independently in each zone:─in the Slow VT and VT zones: two ATP programs, up to two shocks with programmable energy and up to four shocks with maximum energy can be programmed;─in the VF zone: one ATP program, up to two shocks with programmable energy and up to four shocks with maximum energy can be programmed.When the rhythm changes from one zone to another, the device delivers the therapy programmed in this zone, starting with the same or more aggressive program for the area. The ATP program in the VF zone will only be applied if the VT coupling interval is longer than the programmed fast VT cycle length.The PLATINIUM VR offers biphasic shocks with a maximum stored energy of 42 J. The shock configuration (electrodes used to apply the shock) can be chosen by programming one of the following combinations: can and one coil, can and two coils, two coils only.Other features are as follows:─Automatic ventricular sensitivity control─Non-committed shocks─Electrophysiological studies (EPS) with real-time markers or electrograms: ─Programmer-controlled VT induction sequences,─Programmer-controlled VF inductions (30 Hz rapid pacing or shock on T),─Programmable electrogram vectors (RV coil-CAN / SVC coil-CAN /RV coil-SVC coil /RV tip-CAN / RV ring-CAN) and RV EGM, ─Real-time annotations displayed with the markers and indicating the majority rhythm,─Manual ATP sequences,─Manual shocks.─Rescue shock─Follow-up tests: ─Pacing lead impedance,26 SORIN – PLATINIUM VR – U461A
13. DEVICE DESCRIPTION─Coil impedance,─Capacitor charge time,─Pacing threshold tests.─Data storage: ─Therapy History Report,─Statistics (pace/sense, therapy, shocks, and battery voltage),─Up to 16 complete Holter records with event logs, marker channel notation, and electrogram records.The PLATINIUM VR 1210 connector has three ports:─ventricular bipolar pace/sense and─two ports for RV and SVC defibrillation coils.The PLATINIUM VR 1240 connector head has one port: ventricular bipolar pace/sense and RV & SVC defibrillation coils.The pace/sense port is compatible with the IS-1 standard and both defibrillation ports are compatible with the DF-1 standard.The defibrillation port is compatible with the DF-1 standard.Distal lead terminal connections are secured with set-screws accessed via self-sealing silicone plugs. All lead connections pass through the header into the device via feedthroughs.Programming System:The Sorin programmer is used in conjunction with specific programmer software to interrogate and program the implanted device at implant and during patient follow-up procedures.Remote Monitoring:PLATINIUM VR is also equipped with the RF wireless technology which enables to remotely monitor the patients who have the Sorin SMARTVIEW Monitor installed at home.SORIN – PLATINIUM VR – U461A 27
14. IMPLANT PROCEDURE 14. IMPLANT PROCEDURE14.1. NECESSARY EQUIPMENTImplantation of PLATINIUM VR requires the following equipment:─Sorin ORCHESTRA programmer, equipped with the SMARTVIEW software interface and inductive telemetry head,─Sorin ORCHESTRA PLUS programmer, equipped with the SMARTVIEW software interface, inductive telemetry head and optionally ORCHESTRA PLUS LINK,─pacing system analyzer, as well as its sterile connecting cables, to evaluate the pacing and sensing thresholds,─a ventricular pacing and defibrillation lead,─physiological signal monitor capable of displaying simultaneously the surface ECG and arterial pressure,─an external defibrillator with sterile external paddles,─sterile cover for the telemetry head.14.2. PACKAGING14.2.1. ContentsPLATINIUM VR and its accessories are ethylene oxide sterilized and hermetically sealed in two-ply clear packaging meeting international requirements.The sterile packaging contains:─the defibrillator─a ratcheting screwdriver─a DF-1 defibrillating connector insulating plug for 1210 modelOnce delivered, PLATINIUM VR is programmed to as-shipped values that are different from nominal values (see Chapter “Programmable Parameters” for details).14.3. OPTIONAL EQUIPMENTThe following equipment may be required during implantation of PLATINIUM VR:─a DF4/DF-1 adaptor in case of replacement and use of DF-1 lead in a DF4 connector─sterile water to clean traces of blood. Any parts cleaned with sterile water must be thoroughly dried.─mineral oil to lubricate if necessary─a lead cap to isolate a lead which is not used28 SORIN – PLATINIUM VR – U461ANOTE: In case you’re implanting a DF4 lead, please verify its compatibility with standard alligators pin; please refer to the lead user’s manual for more details.
14. IMPLANT PROCEDURE14.4. BEFORE OPENING THE PACKAGEBefore opening the package, check the "Use Before" date printed on the labels on the box and on the sterile package. Defibrillators that have not been implanted before that date should be returned to Sorin.Interrogate the device: ─if a warning is displayed, do not implant the device and contact your Sorin representative.─if battery voltage is below 3V, and if the last reforming/charge occurred more than one week ago, do not implant the device. Otherwise wait for one more week before checking the voltage.NOTE : The battery voltage can decrease before the expiration date is reached. However, the battery voltage should be equal to or higher than 3V at the time of implant.Devices MUST NOT be interrogated and programmed within the vicinity of other devices.Also check the integrity of the sterile package. The sterility of the contents is no longer guaranteed if the package has been pierced or altered. If the defibrillator is no longer sterile, it should be returned in its packaging to Sorin. Any re-sterilization of the unit is at the discretion of Sorin.14.5. PRIOR TO IMPLANTATIONUse the programmer to verify the defibrillator can be interrogated before implantation.Verify all shock therapies are disabled in order to avoid accidental discharge during implantation.It is not advisable to program the Smoothing function before implantation, since the defibrillator may detect noise and pace at a rate higher than the programmed basic rate.14.6. DEVICE PLACEMENTThe pocket should be prepared in the left pectoral position, either subcutaneously or submuscularly. Subcutaneous device implantation is recommended for optimal RF communication efficacy.Implantation in an abdominal position is not advisable.In its final position, the defibrillator should be no more than 4 cm below the skin surface.14.7. CHOOSING THE TYPE OF LEADThe defibrillator should be connected to:─one right ventricular lead with bipolar sensing/pacing electrodes and one or two defibrillation coilsSORIN – PLATINIUM VR – U461A 29CAUTION:Do not shake or tap sharply on the ICD package with the ICD inside, because the ICD's sensing circuits can interpret this as R-waves and record these as an arrhythmia episode.High voltage capacitors charge performed on ICD without connected leads using wireless telemetry can generate false R-waves detection. It is recommended to reset the memory data and statistics before implanting the ICD.
14. IMPLANT PROCEDUREConnectors:PLATINIUM VR 1210:The pacing/sensing connector is compatible with the IS-1 standard and the right ventricular defibrillation connectors are compatible with DF-1 standard.PLATINIUM VR 1240:The quadripolar right ventricular connector is compatible with the DF4 standard.14.8. SHOCK CONFIGURATION (+ -> -)The shock configuration is the energy pathway between the defibrillation electrodes. If an atrial coil is present, the shock configuration can be programmed for bi-directional shocks.Programming:When active case and SVC are both programmed to Yes, the shock configuration can be programmed to: ─RV to Case (or Case to RV),─or RV to SVC (or SVC to RV),─or RV to Case+SVC (or Case+SVC to RV). RV to Case+SVC RV to Case RV to SVCThe polarity of shock is determined by the parameter itself.14.9. MEASUREMENT OF THRESHOLDS AT IMPLANTPacing and sensing thresholds should be measured at implant.Pacing threshold:Acute threshold should be lower than 1 V (or 2 mA) for a 0.35 ms pulse width.30 SORIN – PLATINIUM VR – U461ANOTE 1: Please note that DF-1 standard compliant lead is not compatible with DF4 connector. In the reverse, DF4 standard compliant lead is not compatible with DF-1 connector. In case of defibrillator replacement, choose the appropriate device compatible with DF-1 or DF4 leads. For any other lead type that require an adaptor for this device, please contact your Sorin representative for any information on lead / connector compatibility question.NOTE 2: In the event of a warning on a low shock impedance, and after lead replacement or reconnection: it is recommended to check the system integrity (sensing and pacing thresholds and the impedance of the shock electrodes).
14. IMPLANT PROCEDURESensing threshold:For appropriate ventricular sensing, the amplitude of the R-wave should be greater than 5 mV.Pacing impedance measurement:Ventricular pacing impedance should range from 200 to 3000 ohms (refer to the lead characteristics, especially if high impedance lead is used).Please refer to the lead user manual for more details on the expected electrical performances of the leads.14.10. LEAD CONNECTION Implant the ventricular lead.The lead must be connected to the corresponding connector port. The position of each connector is indicated on the casing.Tighten only the distal insert.To connect the lead, proceed as follows:1. Clean the lead terminal pins thoroughly, if necessary (device replacement).2. Lubricate the lead terminal pins with sterile water, if necessary.3. Do not insert a lead connector pin into the connector block without first visually verifying that the lead port is not filled with any obstacle.4. Insert the screwdriver into the pre-inserted screw socket of the appropriate port (in order to allow excess air to bleed out and to make the insertion of the lead pin easier).5. Insert the lead pin all the way into the port (check that the pin protrudes beyond the distal insert).6. Tighten, check the tightness and ensure the lead pin still protrudes beyond the distal insert, and has not move.1. Do not tighten the pre-inserted screws when there is no lead (this could damage the connector). 2. Do not loosen the screws before inserting the connector (subsequent risk of being unable to reinsert the screw).3. When mineral oil or sterile water is used to make lead insertion easier, the screwdriver should remain inserted into the pre-inserted screw socket when checking the tightness. As a matter of fact, when the lead port is filled with a liquid, the physics piston effect can give the feeling the lead is properly tightened. 4. One single set screw is located on the side of the connection header.5. Use only the screwdriver provided with the defibrillator. Keep the screwdriver's shaft perpendicular to the plane of the defibrillator (see figure below).6. Removing the screwdriver: to avoid all risk of loosening screws during removal, hold the screwdriver by its metal part and not by the handle.SORIN – PLATINIUM VR – U461A 31CAUTION:CAUTION:
14. IMPLANT PROCEDURETo ensure full insertion, push the screwdriver's hex tip smoothly into the setscrew until it reaches the bottom of the hex chamber in the screw, which can be felt as a solid metallic contact. Do not implant the defibrillator if there is no feeling of solid metallic contact. Do not implant the defibrillator if the wrench does not click when attempting to tighten the setscrew on the lead pin.In the case of an external defibrillation shock delivered to the patient, always check the programming and functioning of the device, in particular its capacity to deliver shocks.14.11. DEVICE IMPLANTATIONPLATINIUM VR should be implanted with the device identification engraved side facing outwards for optimal communication with the programming head and radiographic identification.Carefully wind excess lead and place in a separate pocket to the side of the defibrillator.It is recommended not to place any excess wire between the can and the heart.Suture the casing connector to the muscle using the hole provided for this purpose, in order to avoid potential migration of the device into the pectoral muscle.14.12. TESTS AND PROGRAMMINGDuring the implant testing procedure:It is recommended that a security margin of at least 10 J be demonstrated between the effective shock energy and maximum programmable energy.Enable shock therapies, then program the defibrillator.Verify that the defibrillation lead impedance for each shock delivered is within the range of 30 to 150 ohms. Check the lead connection if the values are outside these boundaries.32 SORIN – PLATINIUM VR – U461AWARNING: Ensure that the screwdriver's tip is fully inserted in the setscrew; otherwise the screwdriver can damage the setscrew and prevent connection with or disconnection from the lead.NOTE: To optimize cardioversion/defibrillation shocks, electrodes must be positioned so that the electric field between anode(s) and cathode covers the largest myocardial mass. In normal conditions, the anode and cathode are adequately separated. In case of a short-circuit, the shock may be aborted to prevent damaging the defibrillator.
14. IMPLANT PROCEDURESave the programming data on the programmer’s hard disk and on an external storage device (if desired).Resuscitation Availability:Do not perform device testing unless an external defibrillator is available and medical personnel skilled in cardiopulmonary resuscitation (CPR) are present.Disable the ICD During Handling:Program Shock Therapy to OFF during surgical implant and explant or post mortem procedures. The device can deliver a serious high energy shock should accidental contact be made with the defibrillation electrodes, the device can deliver a very high energy shock.SORIN – PLATINIUM VR – U461A 33
15. SPECIAL MODES 15. SPECIAL MODES15.1. SAFETY MODE (NOMINAL VALUES)Nominal values may be rapidly restored by pressing the following button on the programming head or programmer keyboard:or via the Emergency button on the SMARTVIEW screen.In safety mode, the defibrillator operates with the parameters underlined in the table of programmable parameters.15.2. MAGNET MODEWhen the magnet is applied:─antiarrhythmia functions are inhibited (detection of rhythm disturbances, charging, and therapy),─pacing amplitude is set to 6 V,─pulse width is set to maximum,─the following functions are disabled: Smoothing, Rate Response.When the magnet is removed:─arrhythmia detection algorithms and sequential therapies are reinitialized,─therapies start with the least aggressive program for each area.The antiarrhythmia functions inhibition is extended after magnet removal if a charge occurred just before the application of the magnet in order to ease the communication between the device and the programmer.The other parameters remain at their programmed value.15.3. RESPONSE IN THE PRESENCE OF DISTURBANCEIf the defibrillator senses electrical noise at a frequency above 16 Hz, it switches to an asynchronous mode at the basic rate. The programmed mode is restored as soon as the noise is no longer detected.Ventricular pacing may also be inhibited by ventricular noise. It can be restored by setting the parameter V pacing on noise to Yes.15.4. DETECTION CHARACTERISTICS IN THE PRESENCE OF ELECTROMAGNETIC FIELDSPer Clause 27.4 of Standard EN 45502-2-2, detection in the presence of electromagnetic fields is characterized as follows:─Differential mode:For DF-1 models:34 SORIN – PLATINIUM VR – U461A
15. SPECIAL MODESFor DF4 models:─Common mode rejection ratio:For DF-1 Models:16.6 Hz 50 Hz 60 HzVentricular channel ≥68 dB ≥68 dB ≥68 dBFor DF4 Models:16.6 Hz 50 Hz 60 HzVentricular channel ≥68 dB ≥68 dB ≥68dBFor ventricular sensitivity settings below 0.6mV, the ICD may detect noise lower than the level specified in clause 27.5.1 of standard EN 45502-2-2 for frequencies below 200 Hz.15.5. PROTECTION AGAINST SHORT-CIRCUITSThe defibrillator can undergo a short-circuit if the anode and cathode are not adequately separated.In this case, the shock is aborted to prevent damaging the defibrillator and a warning will indicate that a short circuit (shock impedance < 20 ohms) was detected during the last shock.SORIN – PLATINIUM VR – U461A 35
16. MAIN FUNCTIONS 16. MAIN FUNCTIONS16.1. AUTOMATIC LEAD MEASUREMENTSAutomatic pacing lead impedance measurement:A lead impedance measurement is automatically performed on the lead every 6 hours.The daily mean impedance is stored.Automatic coil impedance measurement:A continuity measurement is automatically performed on defibrillation coil(s) once per day. The continuity is stored for each coil.Automatic sensing measurement:The amplitude of R waves are automatically measured at each cycle. Every 8.5 minutes, the amplitude of the last 8 R detections are averaged and stored.16.2. VENTRICULAR TACHYARRHYTHMIA MANAGEMENTArrhythmia discrimination algorithm Stability/Acceleration and Stability+/Acceleration:Stability/Acceleration is the algorithm used to discriminate sinus tachycardias (ST) and supraventricular tachycardias (SVT) from ventricular tachycardias (VT).Stability+/Acceleration is based on the Stability/Acceleration algorithm but additionally takes into account the “AFdetect” discrimination criteria: the occurrence of a ‘long ventricular cycle’ characteristic for AF patients which is an additional arrhythmia classification criterion to improve identification of atrial fibrillation and avoid inappropriate shocks.Fast VT treatment:Applies detection criteria on fast ventricular tachycardia that are different from those of the VT zone, as well as different therapies. The fast VT zone is included in the VF zone: its lower limit is determined by the programmed value for the VF zone and its upper limit by the programmed value for the fast VT zone.Polarity alternation on Max shock:Reverses the programmed polarity of every second shock set at maximum energy. The number, type, and energy of shocks is independently programmable by detection zone.Defibrillation threshold (DFT):Be aware that the changes in the patient’s condition, drug regimen, and other factors may change the defibrillation threshold (DFT) which may result in non-conversion of the arrhythmia post-operatively. Successful conversion of ventricular fibrillation or ventricular tachycardia during arrhythmia conversion testing is no assurance that conversion will occur post-operatively.36 SORIN – PLATINIUM VR – U461A
16. MAIN FUNCTIONS16.3. PACINGBTO (Brady Tachy Overlap):Allows pacing in the slow VT zone, without affecting arrhythmia detection specificity.Post-shock mode:After any automatic shock therapy, the post-shock mode makes it possible to apply different pacing parameters.16.4. SENSINGAutomatic Refractory Periods:Optimize sensing and make the implant programming easier. These periods are composed of a minimal Refractory Period and a triggerable Refractory Period. The duration of the refractory periods lengthens automatically as needed.Protection against noise:Allows the distinction between ventricular noise and ventricular fibrillation. If the device senses ventricular noise, the ventricular sensitivity is decreased until noise is no longer detected. Ventricular pacing can be inhibited to avoid a potential paced T-wave.Automatic sensitivity control:Optimizes arrhythmia detection and avoids late detection of T-waves and over-detection of wide QRS waves. The device automatically adjusts the sensitivities based on the ventricular sensing amplitude. In case of arrhythmia suspicion or after a paced event, the programmed ventricular sensitivity will be applied. The minimum ventricular sensitivity threshold is 0.4 mV (minimum programmable value).16.5. FOLLOW-UP FUNCTIONStorage of memory data:AIDA+ (Automatic Interpretation for Diagnosis Assistance) software provides access up to 6 months of patient follow-up with day by day data collection, or up to 24 hours with hourly data collection. Episodes of ventricular tachyarrhythmia are recorded with one programmable EGM channel which can be selected, in addition to RV EGM.Alerts / Warnings:The device routinely performs security self-checks and technical measurements to ensure system integrity. When system integrity is found to be at risk outside a follow-up, alerts are stored in the device memory. When system integrity is found to be at risk during a follow-up, the information is managed by a warning (pop-up message) to immediately notify the user. For example, the following types of event can trigger a warning or an alert: technical problem during a shock, lead impedance or shock continuity measurements out-of-range, battery depletion, …16.6. REMOTE MONITORING FUNCTIONRemote monitoring enables the automatic remote transmission of implant data to the physician thanks to the wireless Radio Frequency (RF) communication ability of the implant in order to provide a comprehensive report to the physician about device functioning and patient cardiac status without having the patient physically in the clinic.SORIN – PLATINIUM VR – U461A 37
16. MAIN FUNCTIONSThe data is transmitted from the implant to the SMARTVIEW monitor, a small transmitter placed in the patient's home.Implant data are first transmitted to the SMARTVIEW monitor via RF. Data are then rooted through the phone line or via GPRS to an internet website. This website is responsible for transforming the implant data into a comprehensive report that can be consulted by the physician.16.6.1. SMARTVIEW MonitorThe SMARTVIEW monitor is a small device equipped with an RF transmission module to communicate with the implant and a modem to export data through the internet.The SMARTVIEW monitor is delivered to the patient who has to install it at home. Preferably the SMARTVIEW monitor will be placed on the nightstand of the patient, as close as possible to the side of the bed where the patient usually sleeps. The SMARTVIEW monitor connects to the phone line of the patient and the power plug. Regular transmissions are done during the night when the patient is asleep next to the SMARTVIEW monitor without any intervention from the patient. 16.6.2. Transmission triggerThere are 3 different triggers for a remote transmission:─the remote follow-up transmission is scheduled by the physician to occur regularly (according to the programming).─the alert transmission will take place when the implant has recorded an abnormal event. The list of abnormal event is available in a following paragraph. Alert conditions are checked daily.─the on-demand follow-up transmission is triggered by the patient himself through the use of a specific button on the SMARTVIEW monitor.16.6.3. Data transmittedThe data transmitted are identical to the data available during a standard interrogation with the dedicated programmer. All counters, histograms, IEGMs and diagnosis available in the device are transmitted containing (not exhaustive list):─programmed parameters─information on patient and system implanted─battery status─lead status (brady leads and defibrillation coils) ─pacing counters and mean heart rate (brady)─ventricular arrhythmia counters and episodes─ventricular therapy countersData are presented in the form of 2 reports to the physician: the first one contains a summary of major counters, histograms, warnings and diagnosis. The second one presents the most important IEGM episodes automatically selected based on the degree of severity for the patient.16.6.4. User websiteOn the website, the physician is able to:38 SORIN – PLATINIUM VR – U461A
16. MAIN FUNCTIONS─consult and schedule the remote follow-ups of their patient─configure additional ways of being notified of alerts (for instance by SMS, fax or e-mail)─consult, print and export patient reports 16.6.5. Alert systemThe following set of alert trigger can be independently programmed ON/OFF by the physician using the dedicated programmer and can trigger an alert transmission:─Low or high impedance─Abnormal coil impedance (shock lead)─Low or High shock impedance─Inefficient high energy shock─All shocks programmed OFF─Shock treated VT/VF─ATP treated VT/VF─Suspicion of noise on the V leadThe following set of alert trigger (system alerts) cannot be deactivated when the Alerts are programmed “On” and can trigger an alert transmission:─Battery depletion – RRT─Device reset─Excessive charge time (>25s)─System integritySORIN – PLATINIUM VR – U461A 39WARNING: The use of remote monitoring does not replace regular follow-up. Therefore, when using remote monitoring, the time period between follow-ups visits may not be extended.
17. PATIENT FOLLOW-UP 17. PATIENT FOLLOW-UP17.1. FOLLOW-UP RECOMMENDATIONSBefore the patient is discharged and at each subsequent follow-up visit, it is advisable to:─check the occurrence of system warnings─check the battery status,─check the integrity of the pacing and defibrillation leads,─check for proper sensing (sensitivity) and pacing ; set the pacing amplitude to twice the pacing threshold,─interrogate the implant memories (AIDA+),─check the efficacy of the therapies delivered,─keep a printout of programmed parameters, test results, and memory data,─reset the memory data and statistics.These operations should be performed by medical personnel in an appropriate care unit, with resuscitation equipment present.It is recommended that a routine follow-up examination be done one month after discharge, and then every three months until the device nears the replacement date.Refer to the online help for a description of displayed warning, and the necessity to contact Sorin for an evaluation.Implant software upgrade:In case a new implant software is downloaded in the device memory through the programmer, a warning message could be displayed by the programmer to inform the user and give the correct instructions to follow.17.2. HOLTER FUNCTIONThe Holter records markers and EGM on RV and on 1 programmable channel: RV coil – Can / SVC coil – Can / RV coil - SVC coil / RV tip – Can / RV ring – Can─Up to 10 episodes and 5 min EGM on significant events: lead impedance out of range. ─Up to 16 tachyarrhythmia episodes as well as the therapy history.Stored Tachyarrythmia Episodes:PLATINIUM VR stores up to 16 episodes (VF, VT, Slow VT, SVT/ST, non-sustained) with a total of 25.6 min of high resolution EGM.40 SORIN – PLATINIUM VR – U461ANOTES: If the last reforming, charge or shock occurred during the week preceding the interrogation, the last battery value may be still impacted by the event. One week post event, the battery will recover its steady state value.Automatic capacitor charging may affect communication between the device and the programmer.
17. PATIENT FOLLOW-UPFor each episode four levels of details are presented:─Tachogram─Event log for the entire episode: ─"Arrhythmia Discrimination" analysis for each majority,─Delivered therapies,─Markers: Ventricular markers, sensed, paced and in relative refractory periods,─EGM: onset and detection of the arrhythmia, on two therapies, and the return to slow rhythm by recording electrogram.Therapy historyFor each arrhythmia detection, each therapy delivered (either automatically or during an electrophysiological study) and at the end of each arrhythmia, PLATINIUM VR records the type of majority rhythm, the number of ATP sequences delivered, the energy and the number of shocks delivered.17.3. RECOMMENDED REPLACEMENT TIME (RRT)Recommended Replacement Time (RRT)(1) is controlled by: battery voltage equal to 2.62 V ± 0.01 VBetween the RRT and the EOS (End of Service)(2), PLATINIUM VR can still function for:─14 months (100% pacing in VVI mode, 500 ohms, with as shipped settings), and deliver 15 shocks at 34 J or─10,4 months (0% pacing, sensors OFF, one shock every 2 weeks) and deliver 21 shocks at 34 J. Once the Recommended Replacement Time (RRT) point has been reached, the device operates normally, except that the charge time increases. Under normal conditions (and without programmer use) the charge times are as follows:Shock energy Charge time (sec)BOS(3) 42 J 10 (± 2)RRT 42 J 13 (± 3)(1) Recommended Replacement Time (RRT) corresponds to Elective Replacement Indicators (ERI) previously used.(2) End of Service (EOS) corresponds to End of Life (EOL) previously used.(3) Beginning of Service (BOS) corresponds to Beginning of Life (BOL) previously used.17.4. EXPLANTATIONThe defibrillator should be explanted in the following cases:─The Recommended Replacement Time (RRT) point is reached─Confirmed malfunction─Burial of the patient (for environmental reasons, the local regulation may require the explantation of the devices containing a battery supply)SORIN – PLATINIUM VR – U461A 41CAUTION: The defibrillator should be replaced as soon as the Recommended Replacement Time (RRT) point is reached.
17. PATIENT FOLLOW-UP─Cremation of the patient (the defibrillator may explode if placed in an incinerator)The explanted defibrillator should not be reused in another patient.All explanted defibrillators should be returned to Sorin, carefully cleaned of all traces of contamination. Cleaning may be done by immersing them in an aqueous sodium hypochlorite containing at least 1% chlorine, followed by rinsing copiously with water.The defibrillator should be protected against mechanical impact and the temperature variations that may occur during shipping.Before explantation, it is advisable to:─Print out all programmed parameters, statistics and Holter function report,─Save Patient data on floppy disk or hard disk,─Disable shock therapies (VT and VF) to avoid any risk of untimely shock.17.5. DEFIBRILLATOR IDENTIFICATIONThe defibrillator can be interrogated and programmed via telemetry, using the programming head interfaced with the Sorin dedicated programmer.Position the programming head over the telemetry antenna located in the upper part of the device, in order to communicate effectively via telemetry (see diagram below).The device can be non-invasively identified as follows:1. Take an x-ray to identify the name of the manufacturer and model, printed on the device (X-ray ID is SEA for PLATINIUM range). 2. Interrogate the device using the Sorin dedicated programmer.

When system integrity is found to be at risk outside a follow-up, alerts are stored in the device memory. When system integrity is found to be at risk during a follow-up, the information is managed by a warning (pop-up message) to immediately notify the user. For example, the following types of event can trigger a warning or an alert: technical problem during a shock, pacing lead impedance or coil impedance measurements out-of-range, battery depletion, etc. The Remote tab presents an overview of all the alerts managed by the device.General parameters ValuesRF communication (1) ON-OFFAlerts (1) ON-OFF(1) RF and Remote alerts are turned on automatically if Shocks are programmed ON.When Alerts are programmed "On", the following System Alerts are automatically activated:─Battery depletion – RRT─Device reset─Excessive charge time (>25s)─System integrityLead Alerts ValuesAbnormal lead impedance ON-OFFAbnormal lead low limit (Ohm) 200-250-300-350-400-450-500Abnormal lead high limit (Ohm) 1500-1750-2000-2500-3000Abnormal RV coil impedance ON-OFFAbnormal SVC coil impedance ON-OFFAbnormal Shock impedance (1) ON-OFF(1) Normal impedance range [20 Ohm-200 Ohm]Clinical status ValuesV oversensing ON-OFFSORIN – PLATINIUM VR – U461A 53
