Claim 11:
12. A method of capturing and removing a thrombus from a blood vessel in a human, comprising:
advancing an inner catheter having a thrombus engagement member to a thrombus in the blood vessel;
positioning an outer catheter in the blood vessel such that a distal end of the outer catheter is proximal to the thrombus in the blood vessel;
deploying a filter body having a braided mesh with a tapered proximal end portion and an open distal end such that the open distal end of the filter body self-expands to a diameter of the vessel at a location between the distal end of the outer catheter and the thrombus, wherein a proximal end portion of the filter body is attached to a distal end of the outer catheter;
expanding the thrombus engagement member such that it engages the thrombus and thereby disrupts the thrombus, wherein the thrombus engagement member has flexible radially extending members that diverge radially outward in a distal direction, and wherein the members each have a radially-outward most portion that is at least partially rounded; and
capturing thrombus material with the filter body and holding the captured thrombus material in the filter body while the filter body is withdrawn from the blood vessel.
