Claim 16:
17. The vacuum aspiration system of claim 1 wherein
the on-off control is movable between (a) a closed position in which fluid is prevented from flowing from the aspiration lumen of the first catheter to the flow path and (b) an open position in which fluid is allowed to flow from the aspiration lumen of the first catheter to the flow path;
the aspiration source is configured to generate the negative pressure along the flow path when the on-off control is in the closed position; and
upon user actuation to move the on-off control to the open position with the negative pressure having been generated along the flow path, the flow path is positioned to apply the negative pressure to the aspiration lumen of the first catheter to aspirate the portion of the clot material into the distal end portion of the first catheter and into the aspiration lumen.
