The Boston Scientific RELIANCE 4-FRONT DF4 ICD Defibrillation Lead (REF 636) is a transvenous defibrillation lead engineered for sensing, pacing and high-voltage therapy delivery in conjunction with compatible implantable cardioverter defibrillator (ICD) and CRT-D pulse generators. It utilizes the standardized DF4-LLHH single-connector interface to simplify the header connection and reduce the device pocket footprint.
Key Features
Single-connector DF4-LLHH in-line terminal designed to streamline implantation and minimize set-screw connections.
Dual-coil high-voltage configuration for defibrillation therapy delivery (RV and SVC coils).
Active fixation distal tip for stable endocardial placement.
Steroid-eluting electrode intended to support favorable pacing thresholds.
Silicone and polyurethane composite insulation engineered for durability and handling.
Compatible with Boston Scientific DF4-headered ICD and CRT-D generators.
Clinical Applications
Intended for use as part of an implantable cardioverter defibrillator system for patients indicated for ICD or CRT-D therapy.
Delivers bradycardia pacing, ventricular sensing and high-energy defibrillation/cardioversion shocks.
Suitable for transvenous endocardial placement in the right ventricle.
Refer to the manufacturer Instructions for Use for full indications, contraindications, warnings and precautions.
