Abstract
An atherectomy catheter device includes an improved guidewire system including a guidewire port member secured to the distal tip portion of the outer tubular member of an atherectomy catheter of the coaxial type having large and small concentrically disposed elongated flexible tubular members with a rotating cutter member fixed to the distal end of the inner tubular member. The guidewire is spaced from the cutter head yet controls the cutter disposition relative to the vessel lumen of interest. The inner and outer tubular members are constructed to simultaneously provide flushing liquid and aspirate the cutting site. A method of using the improved catheter is also disclosed.
