Intermedics NEXUS Entra family of pacemakers includes the following: SSI (model 1326); DDD (model 1426); SR (model 1398) and DR (model 1466, 1494). The INSIGNIA I Entra pacemakers are multiprogrammable pacemakers from Guidant. The NEXUS I Entra pacemakers are multiprogrammable pacemakers from Intermedics. The family consists of both dual-chamber and single-chamber models, offering adaptive-rate therapy and providing various levels of therapeutic and diagnostic functionality. The INSIGNIA and NEXUS I Entra adaptive-rate models have an accelerometer, which is a motion sensor that responds to patient activity. Sterilized with gaseous ethylene oxide. RECALL NUMBER # Z-1293-06; PRODUCT b) Guidant INSIGNIA I Ultra family of pacemakers includes the following: SR (models1190); and DR (models1290, 1291). Intermedics NEXUS I Ultra family of pacemakers includes the following: SR (model 1390) and DR (model 1490, 1491). The Intermedics NEXUS I Ultra (models 1390, 1490, 1491) are not available in the US. The INSIGNIA I Ultra pacemakers are multiprogrammable pacemakers from Guidant. The NEXUS I Ultra pacemakers are multiprogrammable pacemakers from Intermedics. The family consists of both dual-chamber and single-chamber models, offering adaptive-rate therapy and providing various levels of therapeutic and diagnostic functionality. These pacemakers include ventricular Automatic Capture which automatically measures the ventricular pacing threshold and adjusts the pacing output to 0.5 V above the measured threshold. Two sensors are available: these adapt the pacing rate to the patient's changing metabolic demand. Minute ventilation responds to changes in respiration, and the accelerometer responds to patient activity (motion). INSIGNIA and NEXUS I Ultra models can use either the accelerometer or minute ventilation sensor, or a blend of both accelerometer and minute ventilation. Sterilized with gaseous ethylene oxide. RECALL NUMBER # Z-1294-06; PRODUCT c) Guidant INSIGNIA I Plus family of pacemakers includes the following: SR (models1194); and DR (models 1297, 1298). Intermedics NEXUS I Plus family of pacemakers includes the following: DR (model 1467, 1468). The INSIGNIA I Plus pacemakers are multiprogrammable pacemakers from Guidant. The NEXUS I Plus pacemakers are multiprogrammable pacemakers from Intermedics. The family consists of both dual-chamber and single-chamber models, offering adaptive-rate therapy and providing various levels of therapeutic and diagnostic functionality. Two sensors are available: these adapt the pacing rate to the patient's changing metabolic demand. Minute ventilation responds to changes in respiration, and the accelerometer responds to patient activity (motion). INSIGNIA and NEXUS I Plus models can use either the accelerometer or minute ventilation sensor, or a blend of both accelerometer and minute ventilation. Sterilized with gaseous ethylene oxide. RECALL NUMBER # Z-1295-06; PRODUCT d) Guidant INSIGNIA I AVT family of pacemakers includes the following: SSI (model 482), VDD (model 882), DDD (model 982), SR (model 1192 and DR (model 1292). Intermedics NEXUS I AVT family of pacemakers includes the following: VDD (model 1428), DDD (model 1432), SR (model 1392) and DR (model 1492). The INSIGNIA I AVT pacemakers are multiprogrammable pacemakers from Guidant. The NEXUS I AVT pacemakers are multiprogrammable pacemakers from Intermedics. The family consists of both dual-chamber and single-chamber models, offering adaptive-rate therapy and providing various levels of therapeutic and diagnostic functionality. These pacemakers include ventricular Automatic Capture which automatically measures the ventricular pacing threshold and adjusts the pacing output to 0.5 V above the measured threshold. The INSIGNIA and NEXUS I Plus adaptive-rate models have an accelerometer, which is a motion sensor that responds to patient activity. Sterilized with gaseous ethylene oxide. RECALL NUMBER # Z-1296-06; THE FOLLOWING DEVICES ARE NOT AVAILABLE IN THE US PRODUCT e) Guidant VENTAK PRIZM VR (model 1860) and VENTAK PRIZM DR (model 1861) Automatic Implantable Cardioverter Defibrillator (AICD), Dual Chamber, Sterilized with gaseous ethylene oxide. Implantable cardioverter defibrillators (ICDs) are designed to detect and terminate ventricular tachycardia (VT) and ventricular fibrillation (VF) and provide bradycardia therapy. Therapies include both low- and high-energy shocks using either a biphasic or monophasic waveform. Bradycardia pacing, including adaptive-rate features, is available to detect and treat bradyarrhythmias and to support the cardiac rhythm after defibrillation therapy. VENAK PRIZM 2 devices offer dual-chamber bradycardia features (atrial and /or ventricular pacing and sensing), and VENTAK PRIZM 2 VR devices offer single-chamber bradycardia features (ventricular pacing and sensing) RECALL NUMBER # Z-1297-06; PRODUCT f) CONTAK RENEWAL TR (models H120, H125) and CONTAK RENEWAL TR2 (models H140, H145). CONTAK RENEWAL TR2 devices are not available in the US. The devices are designed to provide cardiac resynchronization therapy by providing biventricular electrical stimulation to synchronize the right and left ventricular contractions. The device also provides adaptive-rate bradycardia therapy. The pulse generator has independent, programmable outputs for the atrium, right ventricle and left ventricle RECALL NUMBER # Z-1298-06; PRODUCT g) VITALITY (models 1870, 1871, T125, T127, T135) and VITALITY 2 (models T165, T167, T175, T177). Implantable Cardioverter Defibrillators (ICD), are designed to detect and terminate ventricular tachycardia (VT) and ventricular fibrillation (VF) and provide bradycardia therapy (atrial and ventricular pacing). Therapies include both low- and high-energy shocks using either a biphasic or monophasic waveform. Vitality 2 devices also offer a wide variety of antitachycardia pacing schemes to terminate slower, more stable ventricular tachyarrhythmias. Bradycardia pacing, including adaptive-rate features, is available to detect and treat bradyarrhythmias and to support the cardiac rhythm after defibrillation therapy. Devices denoted with DR offer dual-chamber bradycardia features (atrial and/or ventricular pacing and sensing), and the devices denoted with VR offer single-chamber bradycardia features (ventricular pacing and sensing) RECALL NUMBER # Z-1299-06 CODE Affected serial numbers are listed on Guidant's website at www.guidant.com.
