Abstract
According to the invention there is provided an intravascular catheter and thrombectomy procedure utilizing the catheter. The catheter comprises a flexible jacket with a distal working head having a canalizing tip rotatable at high speeds for removing thrombus from the lumen of a vessel. A flexible drive assembly extends through the jacket to rotate the tip and a plurality of infusion ports are formed adjacent the distal end of the jacket, capable of delivering a fluid contrast media at relatively high volumetric flow rates into the lumen of the vessel to locate the site of the thrombus. The canalizing tip is then rotated at high speed to homogenize and remove the thrombus from the lumen.
