The Boston Scientific ENDOTAK RELIANCE DF1 Defibrillation Lead (REF 173) is a transvenous endocardial lead designed for sensing, pacing, cardioversion and defibrillation when connected to a compatible implantable cardioverter defibrillator (ICD) pulse generator. The ENDOTAK RELIANCE family uses a tri-lumen lead body and is engineered to provide stable long-term electrical performance in the right ventricle.
Key Features
- DF-1/IS-1 connector configuration compatible with ICD generators accepting DF-1 high-voltage and IS-1 low-voltage terminals
- Transvenous endocardial right ventricular placement
- Defibrillation, cardioversion, sensing and pacing capability in a single lead body
- Silicone and polyurethane insulation construction typical of the ENDOTAK RELIANCE platform
- GORE expanded PTFE backfill on defibrillation coils on select RELIANCE variants to support extraction (verify variant on labeling)
- Fixation style: Not specified in the located sources for this specific REF — confirm active or passive fixation on product labeling prior to use
Clinical Applications
- Use with a compatible ICD pulse generator for patients indicated for implantable cardioverter defibrillator therapy
- Ventricular sensing and pacing
- High-voltage cardioversion and defibrillation therapy delivery
- Long-term chronic implant in the right ventricle
