ACUITY® Spiral Implantable Lead (CAT#: AM-IA-0113-LY)

Boston Scientific ACUITY® Spiral coronary venous pace / sense leads, Models 4591. The leads have an over-the-wire design with an IS-11 unipolar connector and are dexamethasone acetate -eluting distal to the electrode. The lead is anchored with spiral fixation and the electrode is IROX®-coated (iridium oxide). Placement is achieved by inserting the lead through the coronary sinus and placing it into a branch of the cardiac veins.

• Over-The-Wire Lead Design: The lead design consists of an openlumen conductor coil that tracks over a 0.014-in (0.36-mm) diameter guide wire.
• Steroid: The silicone rubber collar near the electrode contains a nominal dose of 0.45 mg dexamethasone acetate.
• Ring Electrode with IROX Coating: The IROX coated ring electrode provides a pacing and sensing surface in the coronary venous system.
• Pace / Sense Configurations: The ACUITY Spiral lead offers various pace / sense configurations depending upon the programming options of a compatible device.
• Distal Tip: The distal tip is protected by silicone rubber. This protection allows for atraumatic lead advancement through the coronary venous system.
• Spiral Fixation: The distal portion of the lead provides fixation after guide wire removal.
