1. A method for the intravascular treatment of clot material from within a blood vessel of a human patient, the method comprising:
positioning a first catheter within a second catheter such that a distal portion of the first catheter is at a treatment site proximate to the clot material within the blood vessel;
coupling a first pressure source to the first catheter via a fluid control device, wherein (a) opening of the fluid control device fluidly connects the first pressure source to the first catheter and (b) closing of the fluid control device fluidly disconnects the first pressure source from the first catheter;
activating the first pressure source to generate a vacuum while the fluid control device is closed;
opening the fluid control device to apply the vacuum to the first catheter to thereby aspirate at least a portion of the clot material into the first catheter;
coupling a second pressure source to the second catheter; and
activating the second pressure source to generate suction at the distal portion of the second catheter.
