<p>An atherectomy device (1) for reducing stenosis material from a vascular vessel is provided. The atherectomy device includes an elongated flexible tubular member (8) having at least one lumen extending therethrough and having proximal and distal extremities. A flexible drive means (9) disposed within the tubular member is free to move both rotationally and axially therein. A cutting assembly (5) is carried by the distal extremity of the flexible tubular member (8) with a cutter (57) being carried by the distal extremity of the flexible drive means (9) for removing a portion of the stenosis from the vessel wall. An inflatable dilation balloon (7) is carried by the tubular member (8) proximally of the cutter (57) for further reducing the stenosis after initial reduction by the cutter (57).</p> |
