The Boston Scientific RELIANCE 4-FRONT DF4 ICD Defibrillation Lead (REF 683) is a transvenous endocardial lead designed for sensing, pacing, cardioversion, and defibrillation when connected to a compatible implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy defibrillator (CRT-D) with a DF4 header port. The RELIANCE 4-FRONT family is engineered around Boston Scientific's high-voltage lead platform, intended to support reliable shock delivery through the right ventricle.
Key Features
- Single DF4-LLHH connector consolidating pace/sense and high-voltage conductors into one inline connection
- RELIANCE 4-FRONT lead body construction with multi-lumen design for high-voltage performance
- Configured for right ventricular implant with shocking coil(s) for defibrillation therapy
- Compatible with Boston Scientific ICD and CRT-D pulse generators that accept a DF4 lead
- Steroid-eluting tip intended to support stable chronic pacing thresholds
- Detailed dimensions, fixation type, coil configuration, and lead length: Not specified in the located sources
Clinical Applications
- Endocardial sensing and pacing of the right ventricle
- Delivery of cardioversion and defibrillation therapy in patients indicated for ICD or CRT-D systems
- Use as the high-voltage lead component in single-chamber, dual-chamber, or biventricular defibrillation systems where DF4 connectivity is supported
- Specific patient indications, contraindications, and clinical suitability: refer to the manufacturer Instructions for Use
