1. A method for removing thromboembolic material from a blood vessel in a patient, the method comprising:
providing an aspiration catheter having an elongate shaft including an aspiration lumen having a proximal end and a distal end, the proximal end configured to couple to a vacuum source, the distal end having an orifice;
providing an elongate member configured for placement through the aspiration lumen of the aspiration catheter, the elongate member having a proximal portion configured to extend from the proximal end of the aspiration lumen;
inserting a distal portion of the elongate shaft of the aspiration catheter into a blood vessel of a subject and positioning the orifice into or adjacent thromboembolic material within the blood vessel of the subject;
inserting the elongate member into the aspiration lumen of the aspiration catheter;
coupling the proximal portion of the elongate member to a rotating device comprising a body and a rotator, the body configured to be gripped by a user and the rotator configured to rotate the elongate member when the rotating device is coupled to the elongate member;
applying a negative pressure to the aspiration lumen of the aspiration catheter to draw at least a portion of the thromboembolic material into the aspiration lumen;
rotating the elongate member within the aspiration lumen of the aspiration catheter with the rotating device;
monitoring the negative pressure with a pressure transducer; and
measuring one or more deviations in the negative pressure with a measurement device coupled to the pressure transducer.
