1. A method for the treatment of clot material within a vasculature of a patient, the method comprising:
positioning a catheter at least partially within the vasculature proximate to the clot material, wherein the catheter is configured to be fluidically coupled to a pressure source via a fluid control device, and wherein (a) opening of the fluid control device fluidically connects the pressure source to the catheter and (b) closing of the fluid control device fluidically disconnects the pressure source from the catheter;
with the fluid control device closed to inhibit fluid flow from the catheter to the pressure source, activating the pressure source to generate negative pressure within the pressure source; and
after generating the negative pressure, opening the fluid control device to apply the negative pressure to the catheter to generate a flow rate within the catheter of greater than about 60 cubic centimeters per second to thereby aspirate at least a portion of the clot material into the catheter.
