The Boston Scientific ENDOTAK RELIANCE 4-SITE DF4 Defibrillation Lead (REF 262) is a transvenous, single-pass defibrillation lead designed for endocardial placement in the right ventricle and connection to compatible DF4-LLHH implantable cardioverter defibrillator (ICD) and CRT-D pulse generators. The 4-SITE configuration provides pace/sense and high-voltage defibrillation therapy through a single proximal DF4 connector, simplifying the header connection compared with legacy DF-1/IS-1 systems.
Key Features
Single proximal DF4-LLHH connector for streamlined ICD/CRT-D header connection
Dual integrated defibrillation shocking coils (RV and SVC) for high-voltage therapy
Integrated bipolar pace/sense electrodes at the distal tip
ENDOTAK RELIANCE lead platform with backfilled coil technology intended to support extractability
Active or passive distal fixation per the specific model variant (refer to manufacturer IFU)
Silicone insulation with polyurethane or fluoropolymer coatings per manufacturer specification
Clinical Applications
Intended for use as part of an implantable cardioverter defibrillator system in patients indicated for ICD or CRT-D therapy
Endocardial right ventricular sensing, pacing, cardioversion and defibrillation
Compatible with Boston Scientific DF4-LLHH header ICD and CRT-D pulse generators
