The Boston Scientific ENDOTAK RELIANCE 4-SITE DF4 Defibrillation Lead (REF 295) is a transvenous, single-pass implantable defibrillation lead designed for connection to compatible Boston Scientific implantable cardioverter defibrillators (ICDs) and CRT-D devices featuring a DF4 connector port. The lead is engineered to deliver pacing, sensing and high-voltage defibrillation therapy from a single right ventricular position.
Key Features
Single-pass transvenous defibrillation lead with DF4-LLHH connector for streamlined header connection.
Dual shocking coils (right ventricular and superior vena cava) for high-voltage defibrillation therapy.
RELIANCE 4-SITE design intended to support reliable sensing, pacing and shock delivery.
Active or passive fixation configuration as specified by the manufacturer model matrix.
Silicone and polyurethane insulation construction consistent with the ENDOTAK RELIANCE family.
Compatible with Boston Scientific DF4-port ICD and CRT-D pulse generators.
Clinical Applications
Intended for chronic transvenous implantation in patients indicated for ICD or CRT-D therapy.
Supports ventricular pacing and sensing in conjunction with the connected pulse generator.
Delivers high-voltage defibrillation shocks for the treatment of ventricular tachyarrhythmias.
Used in single-chamber, dual-chamber and biventricular ICD system configurations.
