The Boston Scientific ENDOTAK RELIANCE 4-SITE DF4 Defibrillation Lead (REF 292) is a transvenous endocardial lead designed for use with compatible Boston Scientific implantable cardioverter defibrillator (ICD) and CRT-D pulse generators. The lead consolidates pace/sense and high-voltage defibrillation conductors into a single DF4-LLHH in-line connector, simplifying the header interface and reducing the number of set-screw connections at the device pocket.
Key Features
DF4-LLHH in-line connector for streamlined ICD/CRT-D header connection
Integrated bipolar sensing configuration using the distal tip and distal shocking coil
Dual shocking coils (RV and SVC) for high-voltage defibrillation therapy delivery
ENDOTAK RELIANCE platform design intended for transvenous endocardial placement
4-SITE fixation design for right ventricular lead stability
Silicone insulation with polyurethane segments and steroid-eluting collar designed to support chronic implant performance
Clinical Applications
Intended for use as a chronically implanted transvenous lead component of an implantable cardioverter defibrillator or CRT-D system
Supports bradycardia pacing, ventricular sensing, and delivery of cardioversion and defibrillation therapy when connected to a compatible Boston Scientific DF4-compatible pulse generator
Suitable for right ventricular endocardial implantation in patients indicated for ICD therapy per the implanting institution's protocols
