1. A method of removing thrombus from a vessel using a thrombus removal system comprising:
providing an elongate catheter having proximal and distal ends and an inner diameter;
providing an aspiration pump having a sensor, an aspiration container, a non-dampening extension tube and a microprocessor controller, said aspiration pump further having an operable mode that generates a cyclic pressure waveform such that when said aspiration pump is coupled to said catheter positioned within a vessel adjacent a thrombus and operated, said pump controllably cycles supplying negative pressure to said catheter to aspirate a thrombus through the catheter to the pump aspiration container;
positioning the distal end of the catheter within a vessel lumen adjacent a thrombus;
coupling the aspiration pump extension tube to the catheter;
operating the aspiration pump to provide a pressure waveform which includes providing cyclic negative and positive pressure to a lumen of the catheter thereby suctioning thrombus through the catheter lumen and into the aspiration container.
