Claim 21:
22. A method for the intravascular treatment of clot material from within a blood vessel of a human patient, the method comprising:
positioning a distal portion of an aspiration catheter proximate to the clot material within the blood vessel, wherein the aspiration catheter defines an aspiration lumen;
generating vacuum pressure within a barrel of a syringe and storing the vacuum pressure within the barrel;
applying the vacuum pressure to the aspiration lumen to aspirate at least a first portion of the clot material into the aspiration lumen by opening a valve fluidically coupled to the barrel and the aspiration lumen;
determining that a second portion of the clot material remains within the blood vessel;
advancing a clot treatment device having an expandable member through the aspiration lumen such that the clot treatment device is positioned at least partially distal to the second portion of the clot material;
expanding the expandable member of the clot treatment device within the blood vessel distal of the clot material, wherein the expandable member includes a plurality of interconnected struts forming a unitary structure having a conical region and cylindrical region distal of the conical region, wherein the struts form a plurality of first cells in the conical region and a plurality of second cells in the cylindrical region, and wherein the first cells are larger than the second cells; and
proximally retracting the expandable member through the second portion of the clot material to capture and/or disrupt the second portion of the clot material.
