The Boston Scientific RELIANCE 4-FRONT DF4 ICD Defibrillation Lead (REF 682) is a transvenous endocardial lead designed for use with compatible Boston Scientific implantable cardioverter defibrillator (ICD) and CRT-D pulse generators. The lead provides pacing, sensing, and high-voltage defibrillation therapy through a streamlined DF4 (IS4) in-line connector, helping reduce the number of connections at the header and simplifying device pocket management.
Key Features
Streamlined DF4-LLHH in-line connector compatible with DF4-compliant ICD/CRT-D headers.
Active fixation design with extendable/retractable helix for stable right ventricular placement.
Single-coil configuration for high-voltage defibrillation therapy.
Silicone insulation with polyurethane outer layer designed to support long-term mechanical durability.
Steroid-eluting tip intended to support stable chronic pacing thresholds.
Compact lead body intended for compatibility with standard transvenous implant techniques.
Clinical Applications
Intended for use as part of a Boston Scientific ICD or CRT-D system for patients in whom an implantable defibrillator is indicated.
Provides intracardiac sensing and pacing in the right ventricle.
Delivers high-voltage defibrillation and cardioversion therapy via the integrated RV coil.
Suitable for de novo ICD implants and applicable system upgrades where DF4 connector compatibility is confirmed by the implanting physician.
