The Boston Scientific RELIANCE 4-FRONT DF4 ICD Defibrillation Lead (REF 654) is a transvenous defibrillation lead designed for use with compatible implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRT-D) pulse generators that accept the DF4-LLHH connector standard. The 4-FRONT platform integrates pacing, sensing, and high-voltage defibrillation conductors into a single in-line connector, simplifying the implant procedure and reducing the number of header connections required at the device pocket.
Key Features
Single DF4-LLHH in-line connector consolidating pace/sense and high-voltage terminals
Dual-coil transvenous defibrillation lead configuration (RV and SVC shocking coils)
Designed for right ventricular placement with active fixation
Engineered conductor and insulation construction intended to support long-term lead performance
Compatible with Boston Scientific DF4-enabled ICD and CRT-D pulse generators
Clinical Applications
Intended for chronic transvenous implantation as part of an implantable cardioverter defibrillator system
Delivery of high-voltage defibrillation and cardioversion therapy for ventricular tachyarrhythmias
Bradycardia pacing and intracardiac sensing in the right ventricle
Use within ICD and CRT-D systems where a DF4 lead interface is indicated
