The Boston Scientific RELIANCE 4-FRONT DF4 ICD Defibrillation Lead (REF 673) is a transvenous endocardial lead engineered for pacing, sensing, and high-voltage defibrillation therapy delivery in patients receiving an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D). It uses the standardized DF4-LLHH connector to consolidate pace/sense and defibrillation conductors into a single in-line terminal, simplifying header connections in compatible Boston Scientific pulse generators.
Key Features
Single in-line DF4-LLHH connector designed to streamline device connection and reduce setscrew interfaces.
Right ventricular defibrillation lead with integrated pace/sense and high-voltage shocking coils.
Engineered with multi-lumen silicone and polyurethane construction for handling and long-term implant performance.
Designed for compatibility with Boston Scientific DF4-port ICD and CRT-D pulse generators.
Steroid-eluting tip intended to support stable chronic pacing thresholds.
Clinical Applications
Intended for use as a component of an implantable defibrillation system for the detection and treatment of ventricular tachyarrhythmias.
Supports bradycardia pacing and sensing in the right ventricle.
Used as the RV lead in single-chamber, dual-chamber, and CRT-D configurations.
Suitable for transvenous endocardial implantation via standard pectoral access techniques.
