Claim 18:
19. A method for retrieving clot material from within a vessel lumen of a patient, the method comprising:
positioning a mesh within the vessel lumen at or near the clot material, the mesh having a first end portion coupled to an elongate member and a second end portion uncoupled from the elongate member;
expanding the mesh within the vessel lumen into a first position such that at least a portion of the mesh expands into contact with the clot material, wherein the first end portion of the mesh is distal of the second end portion of the mesh when the mesh is in the first position, and wherein the second end portion is configured to expand and engage a wall of the vessel lumen;
promoting adhesion of the clot material to the mesh by delivering an electrical signal to the mesh; and
pulling the elongate member proximally, thereby transforming the mesh into a second position in which the second end portion of the mesh is distal of the first end portion such that the mesh encapsulates at least a portion of the clot material.
