Intended Use

The Phoenix® Atherectomy System is intended for use in atherectomy of the peripheral vasculature. It is not intended for use in coronary, carotid, iliac or renal vasculature.

Device Description

The AtheroMed Phoenix Atherectomy System is a sterile, single-use device designed for atherectomy of the peripheral vasculature. The Phoenix Atherectomy System has two main components: the Phoenix Catheter and the Phoenix Handle.

The Phoenix Catheter is a flexible, over-the-wire (OTW), front-cutting Catheter that continuously captures and clears debulked plaque proximally through the Catheter and Handle into a collection reservoir that resides outside the patient. For use, the Phoenix Catheter is inserted into the Phoenix Handle. The Handle incorporates a self-contained battery-powered motor designed to drive and rotate the cutter of the Phoenix Atherectorny Catheter at its specified rotational speed. The device is activated by an ON/OFF slider switch on the top of the Handle. An optional Wire Support Clip can also be used to clip a guidewire torque device in a fixed position relative to the Handle. The Catheter, Handle, and Wire Support Clip are each packaged separately, as sterile, single-use components of the Phoenix Atherectomy System.

There are three different models of the Phoenix Catheter. Two Phoenix Catheter models track directly over the guidewire with no tip deflection capability. These models are available in 1.8mm and 2.2mm tip diameter sizes. A third, 2.4mm tip diameter model has a Catheter tip design that can be deflected and rotated by the user so that the cutter can eccentrically debulk to a larger diameter than the Catheter's 2.4mm distal cutter. The controls for deflection and rotation are housed in the Phoenix Handle when the Catheter is inserted into the Handle.

All three Phoenix Catheter models are compatible with commercially available 0.014" exchange length (260cm or greater) guidewires, and all use the same Phoenix Handle.
