1. A pumping system for use with a catheter to perform thrombectomy procedures comprising:
an aspiration pump having a housing, a user interface, a microprocessor controller, a pump assembly, a pump inlet, a pump outlet and an aspiration container; and
a flexible pump extension tube having first and second ends and a length extending there between, said extension tube first end being connected to said pump inlet and said second end being connected to a coupler, wherein said coupler is adapted to couple to the proximal end of a catheter;
said aspiration pump further having a first operable mode that generates a negative pressure wave form such that when said aspiration pump is coupled to a catheter positioned within vasculature adjacent a thrombus and operated, said pump controllably supplies negative pressure to said catheter to aspirate a thrombus through the catheter to the pump aspiration container and a second operable mode that generates negative and positive pressure cyclic wave forms such that when said aspiration pump is coupled to a catheter positioned within the vasculature adjacent a thrombus and operated, said pump controllably supplies negative and positive cyclic pressure to said catheter to aspirate a thrombus through the catheter to the pump aspiration container, said aspiration pump being moveable between said first and second operable modes.
