The Boston Scientific RELIANCE 4-FRONT DF4 ICD Defibrillation Lead (REF 665) is a transvenous, active-fixation endocardial lead designed for pacing, sensing, cardioversion and defibrillation therapy when connected to a compatible Boston Scientific implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D). The lead utilizes the DF4-LLHH standardized in-line connector to simplify header connections and reduce the number of set screws at the pulse generator.

Key Features
Single in-line DF4-LLHH connector compatible with DF4-compliant Boston Scientific ICD/CRT-D headers.
Active-fixation distal tip with extendable/retractable helix for targeted right ventricular placement.
RELIANCE 4-FRONT design intended for high-voltage defibrillation therapy delivery.
Steroid-eluting tip designed to help reduce acute inflammatory response at the electrode–tissue interface.
Silicone insulation with additional protective layers consistent with the RELIANCE lead platform.
Configured as a defibrillation lead for use in the right ventricle; coil configuration per product labeling.

Clinical Applications
Intended for chronic transvenous implantation in patients indicated for ICD or CRT-D therapy per physician assessment.
Supports bradycardia pacing, intracardiac sensing, and delivery of high-voltage shock therapy for ventricular tachyarrhythmias.
Used as a component of a complete Boston Scientific defibrillation system; compatibility must be confirmed against the manufacturer's current compatibility matrix and Instructions for Use.
