MR1161-6 ABSTRACT An expandable transluminal atherectomy catheter system (10) is provided which includes an expandable transluminal atherectomy catheter (ETAC) (20), a balloon-on-a-guide wire (30), a sheathing catheter (40) and a rotator unit (60). The balloon-on-a-guide wire (30) is advanced through an arterial system to a predetermined point. The ETAC (20) within a sheathing catheter (40) is advanced over the guide wire cylinder (32). Prior to injection of a medium the sheathing catheter (40) is pulled back to allow spokes (24) of ETAC (20) to expand. The system (10) removes atheromatous plaque to a larger diameter than the diameter of the catheter (20) where it percutaneously penetrates the skin by the anterograde transluminal catheter whose distal end can be expanded after insertion of the catheter (20) into an artery.
