The Boston Scientific ENDOTAK RELIANCE DF1 Defibrillation Lead (REF 139) is a transvenous endocardial defibrillation lead intended for connection to a compatible implantable cardioverter defibrillator (ICD) pulse generator. Engineered as part of the long-established ENDOTAK RELIANCE platform, this lead is designed to deliver high-voltage defibrillation therapy together with bradycardia pacing and intracardiac sensing through a DF1/IS-1 connector configuration. Specific lead length, fixation type, and shocking coil configuration for REF 139 are not specified in the located sources and should be confirmed against the manufacturer's official labeling prior to procurement.
Key Features
- DF1 high-voltage and IS-1 low-voltage connector configuration for compatibility with a broad range of legacy ICD pulse generators
- Transvenous endocardial design intended for right ventricular placement
- Integrated shocking coil(s) for delivery of defibrillation therapy
- Pace/sense electrodes for bradycardia pacing and intracardiac electrogram sensing
- Engineered as part of the established ENDOTAK RELIANCE family of defibrillation leads
- Silicone and/or polyurethane insulation per ENDOTAK RELIANCE platform construction (exact materials for REF 139 not specified in the located sources)
Clinical Applications
- Intended for use with a compatible implantable cardioverter defibrillator system
- Supports delivery of high-voltage defibrillation and cardioversion therapy
- Supports antitachycardia pacing, bradycardia pacing, and sensing functions provided by the connected pulse generator
- Indicated patient population, contraindications, warnings, and precautions are defined by the manufacturer's Instructions for Use and applicable regulatory labeling
