1. A method of aspirating a thrombus from a body lumen via a catheter coupled to a pump assembly, the pump assembly including a pump, the method comprising:
receiving at an aspiration module an input associated with a catheter parameter associated with the catheter coupled to the pump assembly, the aspiration module implemented in at least one of a memory or a processor coupled to the pump assembly;
selecting, via the aspiration module, an aspiration profile associated with the catheter parameter from a list of a plurality of preset aspiration profiles each associated with a different catheter, the aspiration profile including an upper pressure limit, a lower pressure limit, an aspiration speed, and an infusion speed;
sending a first plurality of signals to actuate the pump based on the aspiration profile to operate the pump in a first mode;
receiving at the aspiration module a pressure signal associated with a catheter pressure from a sensor of the pump assembly; and
sending, on a condition that the catheter pressure is below a pressure threshold, a second plurality of signals to actuate the pump based on the aspiration profile to operate the pump in a second mode during which the pump is cycled between the aspiration speed and the infusion speed such that the catheter pressure cycles between the upper pressure limit and the lower pressure limit.
