The Boston Scientific ENDOTAK RELIANCE 4-SITE DF4 Defibrillation Lead (REF 285) is a transvenous endocardial lead designed for use with compatible implantable cardioverter defibrillator (ICD) and CRT-D pulse generators that accept a DF4 connector. The ENDOTAK RELIANCE platform is engineered to deliver pacing, sensing, and high-voltage defibrillation therapy from a single integrated lead body.
Key Features
Single-pin DF4-LLHH connector for streamlined header connections and reduced setscrew handling.
Dual defibrillation shocking coils (right ventricular and superior vena cava) for high-voltage therapy delivery.
4-SITE configuration designed to support pacing, sensing, and defibrillation functions through one transvenous lead.
Silicone and polyurethane-based insulation construction typical of the ENDOTAK RELIANCE family.
True bipolar pacing and sensing architecture.
Compatible with Boston Scientific DF4-headered ICD and CRT-D pulse generators.
Clinical Applications
Intended for chronic transvenous endocardial implantation in the right ventricle as part of an implantable cardioverter defibrillator system. Used by electrophysiology and cardiac surgery teams managing patients indicated for ICD or CRT-D therapy, supporting bradycardia pacing, tachyarrhythmia sensing, and high-voltage defibrillation in line with the manufacturer's instructions for use.
