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.
