The Abbott Durata DF4 ICD Defibrillation Lead (REF 7121Q) is a transvenous defibrillation lead engineered for use with compatible implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRT-D) pulse generators. Featuring a streamlined DF4-LLHH connector standard, the lead is intended to consolidate the high-voltage and pace/sense connections into a single in-line terminal pin to simplify device pocket management.
Key Features
Single in-line DF4-LLHH connector compatible with DF4-compliant Abbott (formerly St. Jude Medical) ICD and CRT-D generators.
Silicone body with Optim insulation co-polymer engineered to enhance abrasion and tear resistance.
Active fixation distal tip with extendable/retractable helix for targeted right ventricular placement.
Steroid-eluting collar designed to help mitigate acute pacing threshold rise.
Defibrillation shocking coil configuration intended for high-voltage therapy delivery in the right ventricle.
Designed for transvenous endocardial implantation through standard access techniques.
Clinical Applications
Intended for use as a chronically implanted defibrillation, pacing, and sensing lead in the right ventricle, in conjunction with a compatible ICD or CRT-D system, for patients indicated for defibrillation therapy and antibradycardia/antitachycardia pacing as determined by the implanting physician. Refer to the manufacturer Instructions for Use for full indications, contraindications, warnings, and precautions.
