The Boston Scientific RELIANCE 4-FRONT DF4 ICD Defibrillation Lead (REF 662) is a transvenous implantable cardioverter defibrillator (ICD) lead engineered for high-voltage defibrillation therapy and pacing/sensing in the right ventricle. The lead utilizes the DF4-LLHH single-connector standard (IS-1/DF-1 functions consolidated into one in-line connector) to simplify pocket management and reduce header complexity when paired with compatible Boston Scientific DF4 ICD and CRT-D pulse generators.
Key Features
- DF4-LLHH connector consolidating pace/sense and high-voltage conductors into a single in-line pin
- Dual-coil defibrillation configuration with RV and SVC shock electrodes
- RELIANCE 4-FRONT platform construction designed for handling and long-term performance
- Active fixation design with extendable/retractable helix for targeted RV placement
- Steroid-eluting tip intended to support stable chronic pacing thresholds
- Compatible with Boston Scientific DF4-headered ICD and CRT-D pulse generators
Clinical Applications
- Delivery of high-voltage defibrillation and cardioversion therapy in patients indicated for ICD or CRT-D therapy
- Right ventricular pacing and intracardiac sensing as part of an ICD/CRT-D system
- Use in single-chamber, dual-chamber, and biventricular defibrillation system configurations
