The Boston Scientific ENDOTAK RELIANCE 4-SITE DF4 Defibrillation Lead (REF 282) is a transvenous, endocardial pace/sense and defibrillation lead designed for chronic implantation in the right ventricle. It utilizes the standardized DF4-LLHH in-line connector to simplify ICD header connections by combining pace/sense and high-voltage conductors into a single terminal pin.
Key Features
- DF4-LLHH in-line connector compatible with DF4-equipped Boston Scientific ICD and CRT-D pulse generators
- Dual-coil (RV and SVC) high-voltage configuration for defibrillation therapy
- 4-SITE shock vector design intended to support effective energy delivery
- RELIANCE platform construction with redundant cable conductors for high-voltage integrity
- Active or passive fixation variants within the RELIANCE family (verify specific REF 282 fixation type with manufacturer documentation)
- Steroid-eluting tip intended to reduce acute inflammatory response at the electrode-tissue interface
- Silicone and polyurethane lead body insulation typical of the ENDOTAK RELIANCE series
Clinical Applications
- Bradycardia pacing and ventricular sensing in patients indicated for an implantable cardioverter defibrillator (ICD)
- Delivery of high-voltage defibrillation and cardioversion therapy for ventricular tachyarrhythmias
- Use in single-chamber, dual-chamber, or CRT-D systems employing DF4 connector technology
- Suitable only for patients meeting institutional and manufacturer indications for transvenous ICD lead implantation
