The Boston Scientific RELIANCE 4-FRONT DF4 ICD Defibrillation Lead (REF 650) is a transvenous defibrillation lead engineered for reliable sensing, pacing, and high-voltage therapy delivery when paired with DF4-compatible implantable cardioverter defibrillators (ICDs). The RELIANCE 4-FRONT family is part of Boston Scientific's portfolio of cardiac rhythm management leads and is intended for hospital and cardiac catheterization laboratory procurement programs.
Key Features
Single-coil defibrillation lead configuration for streamlined implant and explant considerations.
DF4-LLHH connector standard for a single in-line connection to compatible ICD pulse generators, simplifying header connections versus legacy DF-1/IS-1 systems.
Active fixation distal tip designed to support stable lead placement in the right ventricle.
Silicone and polyurethane lead body construction consistent with the RELIANCE 4-FRONT platform for handling and durability.
Designed to deliver high-voltage defibrillation therapy, anti-tachycardia pacing, bradycardia pacing, and intracardiac sensing.
Engineered to be compatible with Boston Scientific DF4-LLHH ICD and CRT-D pulse generators.
Clinical Applications
Intended for use as a chronically implanted transvenous defibrillation lead in patients indicated for ICD or CRT-D therapy, per the implanting physician's clinical judgment.
Supports detection and termination of ventricular tachyarrhythmias when connected to a compatible ICD system.
Used in initial ICD/CRT-D implants where a single-coil DF4 right ventricular lead configuration is selected.
Suitable for cardiology and electrophysiology procurement for cardiac rhythm management inventories. Clinical suitability for any individual patient must be determined by the treating physician in accordance with the current Instructions for Use.
