Claim 0:
1. A system for removing a vascular thrombus from a blood vessel of a patient, comprising:
a catheter having a lumen and a distal end portion;
a self-expanding filter body including a permeable mesh configured for blood to pass therethrough and having a proximal end portion with a tapered shape and an open distal end sized to conform to an inner wall of the blood vessel when deployed in the blood vessel, wherein the distal end of the self-expanding filter body is configured to be deployed distally with respect to the distal end portion of the catheter; and
an inner elongated member configured to extend through the lumen of the catheter and through the self-expanding filter body, the inner elongated member having a thrombus engagement member, and the thrombus engagement member having flexible radially extending members that diverge radially outward in a distal direction and are expandable to an expanded profile having an expanded diameter sized for contacting the thrombus when deployed in the blood vessel, wherein the members each have a radially-outward most portion that is at least partially curved, and wherein the inner elongated engagement member and the thrombus engagement member are longitudinally slidable for disrupting and removing the thrombus from the blood vessel;
wherein the self-expanding filter body is adapted for capturing thrombus material that has been acted upon by the thrombus engagement member.
