8. 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 catheter proximate to the clot material within the blood vessel;
coupling a first syringe to the catheter via a fluid control device, wherein (a) opening of the fluid control device fluidly connects the first syringe to the catheter and (b) closing of the fluid control device fluidly disconnects the first syringe from the catheter;
withdrawing a plunger of the first syringe to generate a vacuum while the fluid control device is closed;
opening the fluid control device to apply the vacuum to the catheter to thereby aspirate blood and at least a portion of the clot material through the catheter and into the first syringe;
coupling the first syringe to a first connector of a filter device;
depressing the plunger of the first syringe to drive the blood and the portion of the clot material into a chamber of the filter device; and
withdrawing a plunger of a second syringe coupled to a second syringe of the filter device to draw the blood through a filter within the chamber of the filter device and into the second syringe, wherein the filter is sized to inhibit the clot material from passing therethrough.
