Claim 23:
24. 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 a first catheter at a treatment site proximate to the clot material within the blood vessel;
activating a first pressure source fluidly coupled to the first catheter to apply first vacuum pressure to a lumen of the first catheter to aspirate the clot material toward the distal portion of the first catheter;
determining that at least a portion of the clot material is clogging the lumen of the first catheter after activating the first pressure source;
advancing a second catheter through the lumen of the first catheter such that a distal portion of the second catheter is positioned proximate to the clogging clot material; and
activating a second pressure source fluidly coupled to the second catheter to apply second vacuum pressure to a lumen of the second catheter to break apart the clogging clot material.
