6 – US-ENGLISH 1. GENERAL DESCRIPTION PARADYM RF VR 9250 is an implantable single-chamber cardioverter defibrillator. It is equipped with an accelerometer to allow adaptation of pacing to suit the patient’s activity. 2. INDICATIONS This device 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). NOTE: The clinical outcome for hemodynamically stable VT patients is not fully known. Safety and effectiveness studies have not been conducted. 3. CONTRAINDICATIONS Implantation of PARADYM RF VR 9250 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.
US-ENGLISH – 7 4. WARNINGS AND PRECAUTIONS The 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 electromagnetic interference are: powerful radiofrequency equipment (radar), industrial motors and transformers, arc-welding equipment, high power loudspeakers. Resuscitation Availability: Do not perform device testing unless an external defibrillator and medical personnel skilled in cardiopulmonary resuscitation (CPR) are readily available. 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. 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. 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. High voltage power transmission lines: High voltage power transmission lines may generate enough EMI to interfere with defibrillator operation if approached too closely.
8 – US-ENGLISH Communication equipment: Communication equipment such as microwave transmitters, linear power amplifiers, or high-power amateur transmitters may generate enough EMI 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 EMI to interfere with defibrillator operation. There are reports of device disturbances caused by electric hand tools or electric razors used directly over the device implant site. CAUTION: 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. 4.1. RISKS RELATED TO MEDICAL ENVIRONMENT It 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. A radio frequency ablation: A radio frequency 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.
US-ENGLISH – 9 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: PARADYM RF VR 9250 is protected from external defibrillation shocks. Before external defibrillation, deactivate ATP and shock therapies. 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. Avoid any direct contact between the defibrillation paddles and the conductive parts of the implanted leads or casing of the implanted device. 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 screen. 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 this one 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. Diagnostic ultrasound (echography): The defibrillator is not affected by ultrasound imaging devices.
10 – US-ENGLISH Scales with body fat monitors and electronic muscle stimulators: A patient with an implanted PARADYM RF VR 9250 should not use these devices. 4.2. STERILIZATION, STORAGE AND HANDLING Resterilization: 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 CRM. 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 interference 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.
US-ENGLISH – 11 4.3. IMPLANTATION AND DEVICE PROGRAMMING Use only a Sorin CRM programmer to communicate with the device. Do not position any magnet over the ICD; this suspends tachyarrhythmia detection and treatment. Replace the device when the programmer displays an ERI* (defined by a battery voltage of 2.66 ± 0.01 V or a magnet rate lower than or equal to 80 bpm). 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 wrench into the perforation at an angle perpendicular to the connector receptacle may result in damage to the sealing system and its self-sealing properties. A safety margin of at least 10 J in the defibrillation threshold (DFT) is recommended. 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 Recommended Replacement Time (RRT) / End of Service (EOS) as referred in the EN45502-2-2 standard.
12 – US-ENGLISH 4.4. LEAD EVALUATION AND LEAD CONNECTION PARADYM RF VR 9250 has two DF-1 and one IS-1 connector ports. 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). 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.
US-ENGLISH – 13 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. Do 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 DISPOSAL Interrogate 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.

The data provided are applicable to PARADYM RF VR 9250. 5.1. DEFENDER STUDY Clinical 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. NOTE: The company classified as complications those adverse device effects that were treated with surgery or with external defibrillation of a ventricular cardiac event. 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. NOTE: The company classified as observations those adverse device effects that were treated with programming changes, medication, or other method that was not classified as a complication.
US-ENGLISH – 15 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. There were no observations or complications in the U.S. 5.2.

The data provided are applicable to PARADYM RF VR 9250. 6.1. DEFENDER STUDY Objectives: 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.

US-ENGLISH – 23 7. PATIENT SELECTION AND TREATMENT 7.1. INDIVIDUALIZATION OF TREATMENT Exercise 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. CAUTION: To avoid inappropriate therapy during an exercise stress test, do not reprogram any parameter during the test. When a parameter is reprogrammed, "Discrimination" 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. 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.
24 – US-ENGLISH 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 CRM’s representative. 7.2. SPECIFIC PATIENT POPULATIONS Pregnancy: If there is a need to image the device, care should be taken to minimize radiation exposure to the fœtus 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.
US-ENGLISH – 25 8. PATIENT COUNSELLING INFORMATION The 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 CRM ID cards and/or ID bracelets documenting their ICD system. 9.

US-ENGLISH – 31 13. DEVICE DESCRIPTION The PARADYM RF VR system includes the model 9250 ICD device and programming system. The programming system includes the Sorin CRM Orchestra Plus programmer with the SMARTVIEW programming software connected to a CPR3 programming head. The programming system is configured and furnished by Sorin CRM. The PARADYM RF VR 9250 can serve as a defibrillation electrode (active housing) with a total surface area of 76 cm². The PARADYM RF VR 9250 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. PARADYM RF VR 9250 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, PARADYM RF VR 9250 offers programmable single-chamber pacing therapy with or without rate-responsive capabilities using an acceleration sensor. PARADYM RF VR 9250 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.
32 – US-ENGLISH The PARADYM RF VR 9250 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 2 coils, 2 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 ( EGM V, RVcoil-CAN, SVC-CAN, RVcoil-SVC)  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,  Coil impedance,  Capacitor charge time,  Pacing threshold tests.  Data storage:  Therapy History Report,  Statistics (pace/sense, therapy, shocks, and battery voltage),  Up to 14 complete Holter records with event logs, marker channel notation, and electrogram records.
US-ENGLISH – 33 The connector head has three ports: ventricular bipolar pace/sense and two ports for RV and 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. 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 CRM 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: The PARADYM RF VR 9250 is also equipped with the RF wireless technology which enables to remotely monitor the patients who have the Sorin CRM SMARTVIEW Monitor installed at home. 14. IMPLANT PROCEDURE 14.1. NECESSARY EQUIPMENT Implantation of PARADYM RF VR 9250 requires the following equipment:  Sorin CRM dedicated programmer, equipped with the SMARTVIEW software interface and with the programming head,  pacing system analyser, 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.
34 – US-ENGLISH 14.2. PACKAGING  Contents The PARADYM RF VR 9250 and its accessories are ethylene oxide sterilized and hermetically sealed in two-ply clear packaging meeting international requirements. The sterile packaging contains a defibrillator, one screwdriver, and an insulating plug for the DF-1 defibrillation connector. The non-sterile items contained in the outer storage package are the implant manual, the ICD Registration Form and its envelope, the patient booklet, the ICD ID card and 12 identification labels. Once delivered, PARADYM RF VR 9250 is programmed to as-shipped values that are different from nominal values (see Chapter “Programmable Parameters” for details). 14.3. OPTIONAL EQUIPMENT The following equipment may be required during implantation of PARADYM RF VR 9250:  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 used 14.4. BEFORE OPENING THE PACKAGE Before 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 CRM. Devices MUST NOT be interrogated and programmed within the vicinity of other devices.
US-ENGLISH – 35 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 CRM. Any re-sterilization of the unit is at the discretion of Sorin CRM. 14.5. PRIOR TO IMPLANTATION Use 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. CAUTION: 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. If unusual shaking or tapping of the package results in a stored arrhythmia episode, erase the recording before using the ICD. 14.6. DEVICE PLACEMENT The 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.
36 – US-ENGLISH 14.7. CHOOSING THE TYPE OF LEAD The defibrillator should be connected to:  one ventricular defibrillation lead with sensing/pacing bipolar electrodes, and one or two defibrillation electrodes. The choice of leads and their configuration is left to the implanting physician’s judgment. Connectors: The bipolar pacing/sensing connector is compliant with the IS-1 standard and the defibrillation connectors are compliant with the DF-1 standard.  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: 1. RV to Case (or Case to RV), 2. RV to SVC (or SVC to RV), 3. RV to Case+SVC (or Case+SVC to RV). The polarity of shock is determined by the parameter itself. RV to Case+SVC RV to Case RV to SVC
US-ENGLISH – 37 14.8. MEASUREMENT OF THRESHOLDS AT IMPLANT Pacing and sensing thresholds should be measured at implant. Pacing threshold: Acute thresholds should be lower than 1 V (or 2 mA) for a 0.35 ms pulse width. Sensing threshold: For proper 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). 14.9. LEAD CONNECTION The lead must be connected to the corresponding connector port. The position of each connector is indicated on the casing. CAUTION: Tighten only the distal insert. To connect each 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 did not move.
38 – US-ENGLISH CAUTION: 1. One single set screw is located on the side of the connection header. 2. Do not tighten the pre-inserted screws when there is no lead (this could damage the connector). 3. Do not loosen the screws before inserting the connector (subsequent risk of being unable to reinsert the screw). 4. Removing the screwdriver: to avoid all risk of loosening screws during removal, hold the screwdriver by its metal part and not by the handle. 5. 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. NOTE: To optimise 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. 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. 14.10. DEVICE IMPLANTATION PARADYM RF VR 9250 should be implanted with the engraved side facing outwards for optimal communication with the programming head and radiographic identification. Place the device in the pocket. Once in place, the defibrillator should be no more than 4 cm below the skin surface. Carefully wind excess lead and place in a separate pocket to the side of the defibrillator. It is recommended to not place any excess wire between the can and the heart.
US-ENGLISH – 39 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. 14.11. TESTS AND PROGRAMMING During 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 ranges from 30 to 150 ohms. Check the lead connection if the values are outside these boundaries. Save the programming data on the programmer’s hard disk and on an external storage device (if desired). 15. SPECIAL MODES 15.1. 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.
40 – US-ENGLISH 15.2. MAGNET MODE When 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,  pacing rate is set to the magnet rate,  the following functions are disabled: Smoothing, Rate Response. When the magnet is removed:  the sensor rate is forced to the basic rate,  arrhythmia detection algorithms and sequential therapies are reinitialized,  therapies start with the least aggressive program for each area. The other parameters remain at their programmed value. The magnet rate values are as follow: Magnet rate (bpm) 96 94 91 89 87 85 Magnet period (ms) 625 641 656 672 688 703 Magnet rate (bpm) 83 82 80 78 77 Magnet period (ms) 719 734 750 766 781 15.3. RESPONSE IN THE PRESENCE OF INTERFERENCE If 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 is also inhibited by ventricular noise. It can be restored by setting the parameter V pacing on noise to Yes.
US-ENGLISH – 41 15.4. DETECTION CHARACTERISTICS IN THE PRESENCE OF ELECTROMAGNETIC FIELDS Per Clause 27.4 of Standard EN 45502-2-2, detection in the presence of electromagnetic fields is characterized as follows:  Differential mode:  Common mode rejection ratio: 16.6 Hz 50 Hz 60 Hz Ventricular channel ≥ 69 dB ≥ 69 dB ≥ 69 dB 15.5. PROTECTION AGAINST SHORT-CIRCUITS The 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.
42 – US-ENGLISH 16. MAIN FUNCTIONS 16.1. AUTOMATIC LEAD MEASUREMENTS Automatic 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 coil impedance measurement is automatically performed on RV and SVC coils once a week. The result is stored in the device memory. 16.2. VENTRICULAR TACHYARRHYTHMIA MANAGEMENT Searching for a long cycle (Stability+): Additional arrhythmia classification criterion to improve identification of atrial fibrillation and avoid inappropriate shocks. Fast VT treatment: Applies detection criteria on fast ventricular tachycardiathat 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. 16.3. PACING BTO (Brady Tachy Overlap): Allows pacing in the slow VT zone, without affecting detection specificity. Post-shock mode: After any automatic shock therapy, the post-shock mode makes it possible to apply different pacing parameters.
US-ENGLISH – 43 16.4. SENSING Automatic Refractory Periods: Optimize sensing and make the implant progamming 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 FUNCTIONS Storage 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 the programmable EGM channels: either by selecting up to two traces, or by selecting "V-Double" which enables a one-channel recording that is twice as long. 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 as a warning (pop-up message) to notify immediately the user.
44 – US-ENGLISH 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,… 16.6. REMOTE MONITORING FUNCTION Remote 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. The data is transmitted from the implant and the SMARTVIEW monitor, a small transmitter placed in the patient home. Implant data are first transmitted to the SMARTVIEW monitor via RF. Data are then rooted through the phone network to an internet website. This website is responsible for transforming the implant data into a comprehensive report that can be consulted by the physician.  SMARTVIEW Monitor The 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 the patient usually sleeps. The SMARTVIEW monitor shall be connected to the phone network 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.
US-ENGLISH – 45  Transmission trigger There 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 remote-monitor.  Data transmitted The data transmitted are identical to the data available during a standard interrogation with the Orchestra Plus 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)  atrial and ventricular arrhythmia counters and episodes  ventricular therapy counters  heart failure monitoring Data 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 3 most important IEGM episodes automatically selected based on the degree of severity for the patient.
46 – US-ENGLISH  User website On the website, the physician is able to:  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  Alert system The following set of alert trigger can be independently programmed ON/OFF by the physician using the Orchestra Plus programmer and can trigger an alert transmission:  Reset of the device  ERI reached  Low or high impedance (A, RV, LV)  Abnormal coil impedance (shock lead)  Low or High shock impedance  Long charge time  Inefficient high energy shock  All shocks programmed OFF  Shock treated VT/VF  Lack of V pacing in CRT device  Suspicion of noise on the V lead  Fast V rate during AF WARNINGS 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. When ERI mode is reached, this information is transmitted via the remote monitoring facility and then the remote-monitoring is switched off to preserve battery life.
US-ENGLISH – 47 17. PATIENT FOLLOW-UP 17.1. FOLLOW-UP RECOMMENDATIONS Before 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. After a device reset, the magnet rate is equal to 87 ppm; it will be updated within the next 24 hours. Refer to the online help for a description of displayed warning, and the necessity to contact Sorin CRM 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 proper instructions to follow.
48 – US-ENGLISH 17.2. HOLTER FUNCTION The Holter records 14 tachyarrhythmia episodes as well as the therapy history. STORED EPISODES PARADYM RF VR 9250 stores 14 episodes (VF, VT, Slow VT, SVT/ST, nonsustained). For each episode four levels of details are presented:  Tachogram  Event log for the entire episode:  "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 history: For each arrhythmia detection, each therapy delivered (either automatically or during an electrophysiological study) and at the end of each arrhythmia, PARADYM RF VR 9250 records the type of majority rhythm, the number of ATP sequences delivered, the energy and the number of shocks delivered..
US-ENGLISH – 49 17.3. ELECTIVE REPLACEMENT INDICATOR (ERI) Elective Replacement Indicators (ERI)(1) are:  magnet rate equal to 80 ± 1 min-1 or  battery voltage equal to 2.66 V ± 0.01 V CAUTION: The defibrillator should be replaced as soon as the Elective Replacement Indicator (ERI) point is reached. Between the ERI and the EOL (End of Life)(2), PARADYM RF VR 9250 can still function for:  9.7 months (100% pacing in VVI mode, 500 ohms, with as-shipped settings), and deliver 7 shocks at 34 J or  6.4 months (0% pacing, sensor OFF, one 42 J shock every 2 weeks). Once the Elective Replacement Indicator (ERI) 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) BOL 42 J 10 (± 2) ERI 42 J 13 (± 3) (1) Elective Replacement Indicators (ERI) corresponds to Recommended Replacement Time (RRT) as referred in the EN45502-2-2 standard. (2) End of Life (EOL) corresponds to End of Service (EOS) as referred in the EN45502-2-2 standard.
50 – US-ENGLISH 17.4. EXPLANTATION The defibrillator should be explanted in the following cases:  The Elective Replacement Indicator (ERI) 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)  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 CRM, carefully cleaned of all traces of contamination. This 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.
US-ENGLISH – 51 17.5. DEFIBRILLATOR IDENTIFICATION The defibrillator can be interrogated and programmed via telemetry, using the programming head interfaced with the Sorin CRM dedicated programmer.

US-ENGLISH – 69 22. LIMITED WARRANTY The PARADYM RF implantable cardioverter defibrillator is the result of highly advanced research and all components have been selected after exhaustive testing. Sorin CRM S.r.l. (identified as “Sorin CRM” hereafter) guarantees the product PARADYM RF against any damage caused by component failure or production defects during a period of four years after the implantation date, and Sorin CRM commits itself to replace all PARADYM RF devices according to the terms described in article 1 and described in article 2 of this section. Sorin CRM makes no claim that the human body will not react unsuitably to the implantation of the PARADYM RF device, or that failure will never occur. Sorin CRM does not guarantee the suitability of PARADYM RF in defined types of patients; selection of the device is a medical decision. Sorin CRM shall not be held liable for any damage indirectly associated with the PARADYM RF, whether as part of normal or abnormal operation, nor damage from its explantation or replacement. Sorin CRM does not authorise anyone to modify these limited warranty conditions. 22.1. ARTICLE 1 : TERMS OF LIMITED WARRANTY 1. The PARADYM RF implantable cardioverter defibrillator is only guaranteed for one implantation. 2. The EURID/IAPM implant form must be sent to Sorin CRM within 30 days after implantation. 3. The PARADYM RF cardioverter defibrillator must be implanted prior to the use-before date indicated on the packaging.
70 – US-ENGLISH 4. The limited guarantee only applies to suspect devices returned to the manufacturer, carefully packed and accompanied by an explantation report duly completed by the hospital or the doctor and considered defective after analysis by Sorin CRM. The device must be returned within the 30 days following explantation to Sorin CRM. Any device returned and replaced under the terms of this limited warranty will become the exclusive property of Sorin CRM. Any rights under the terms of this limited warranty will be forfeited if the PARADYM RF device has been opened by anyone other than Sorin CRM. These rights will also be forfeited if the device has been damaged by carelessness or accident. This is the case especially if the device has been exposed to temperatures above 50°C, to electrical abuse or to mechanical shock, particularly as a result of being dropped. Consequently, any expert opinion offered by a third party after the device has been removed also nullifies the guarantee. 5. The limited warranty will be forfeited if it is proven that the device has been misused or inadequately implanted, against the physicians’manual recommendations of PARADYM RF. 6. The limited warranty does not include leads and other accessories used for the implantation. 7. The replacement terms or conditions described in article 2 include all devices that shall be replaced within the limited warranty period because of battery depletion, without any link to a component failure or a production hazard. The device battery longevity varies with the type and number of delivered therapies. 8. Legal requirements of jurisdictions where the PARADYM RF device is distributed will supersede any warranty conditions indicated in this manual that conflict with such laws.
US-ENGLISH – 71 22.2. ARTICLE 2 : TERMS OF REPLACEMENT 1. In case of PARADYM RF failure because of a component failure, a production defect, or a conception error, occurring within two-year period starting from the implantation date, Sorin CRM is committed to:  replacing free of charge the explanted device by a Sorin CRM device with equivalent features,  or issuing a replacement credit equal to the purchase price for the purchase of any other Sorin CRM replacement device. 2. After a two-year period and up to 4 years after the implantation, Sorin CRM, because of limited warranty terms, will issue a replacement credit to the buyer of an amount equivalent to half of the initial purchase price minus prorata temporis during this two-years period. 3. In any case the credit issued by the limited warranty terms cannot exceed the purchase price of a Sorin CRM replacement device.
