Claim 0:
1. A system for removing a vascular thrombus from a blood vessel of a patient, comprising:
an outer catheter having a lumen and a distal end portion;
a self-expanding filter body including a permeable braided mesh configured capture and hold clot material while the self-expanding filter body is withdrawn, and the self- expanding filter body also being configured for blood to pass therethrough and having a proximal end portion with a tapered shape and an open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 proximal end portion of the self-expanding filter body is attached to the distal end portion of the outer catheter and the distal end of the self-expanding filter body is configured to be deployed distally with respect to the distal end portion of the outer catheter; and
an inner catheter configured to extend through the lumen of the outer catheter and through the self-expanding filter body, the inner catheter 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 rounded, and wherein the inner catheter and 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 disrupted by the thrombus engagement member.
