The Boston Scientific ENDOTAK RELIANCE 4-SITE DF4 Defibrillation Lead (REF 275) is a transvenous endocardial defibrillation and pacing/sensing lead designed for use with compatible Boston Scientific implantable cardioverter defibrillator (ICD) and CRT-D pulse generators featuring the DF4 connector standard. The ENDOTAK RELIANCE family is engineered to support reliable high-voltage defibrillation therapy along with bradycardia pacing and sensing in a single integrated lead body.
Key Features
DF4-LLHH connector compatible with DF4-enabled Boston Scientific ICD and CRT-D devices.
4-SITE configuration providing defibrillation, pacing and sensing functionality.
Dual-coil transvenous design with right ventricular (RV) and superior vena cava (SVC) shocking electrodes.
Steroid-eluting tip intended to help reduce acute and chronic pacing thresholds.
Silicone and polyurethane lead body construction for handling and long-term performance.
Streamlined single-port DF4 termination to simplify header connections and reduce set screw interfaces.
Clinical Applications
Intended for chronic transvenous endocardial implantation in patients indicated for ICD or CRT-D therapy.
High-voltage defibrillation and cardioversion therapy delivery.
Bradycardia pacing and intracardiac electrogram sensing.
Use with compatible Boston Scientific DF4 pulse generators as specified in the device IFU.
