Abstract: A catheter device is provided that has a first end and a second end. The first end has a first rigid ring disposed thereon. The first rigid ring has an occlusion engaging feature disposed at a free end thereof. The second end has a second rigid ring disposed thereon. The second rigid ring has an occlusion engaging feature disposed at a free end thereof An elongate body extends between the first end and the second end. The elongate body has a lumen extending therethrough. A handle is configured such that a body thereof can be removeably coupled with the elongate body at a first position adjacent to the first end. The handle is configured such that the body thereof can be removeably coupled with the elongate body at a second position adjacent to the second end.

Abstract: A system is provided for crossing an occlusion within a blood vessel or cylindrical body cavity. The system includes a guide catheter and a catheter device. The guide catheter comprises a proximal portion to be disposed outside a patient and a distal portion to be disposed inside the patient adjacent to an occlusion. The system has an expandable member disposed adjacent to a distal end thereof. The expandable member can be coupled with the guide catheter or the catheter device, or an expandable member can be coupled with each of the guide catheter and the catheter device. The catheter device, which can be configured for treating an occlusion, includes a proximal portion, a distal portion, or an elongate body extending between the proximal and distal portions.

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.
