1. A method of removing a thrombus from a body lumen via a catheter coupled to a pump assembly, the pump assembly including a pump, the method comprising:
sending, via an aspiration module operably coupled to the pump assembly, a plurality of signals to the pump assembly to operate the pump assembly in a cycling extraction mode during which the pump is cycled between an aspiration speed and an infusion speed for a plurality of cycles such that a catheter pressure cycles between an upper pressure limit and a lower pressure limit;
determining, at the aspiration module, a cycle time ratio of an aspiration time to an infusion time for each cycle of the plurality of cycles; and
sending a notification to reposition a tip of the catheter on a condition that the cycle time ratio is within a ratio range over a threshold number of cycles of the plurality of cycles.
