Claim:
1. A thrombectomy system comprising: an elongate catheter shaft configured to be inserted within a patient's vasculature and comprising a low pressure lumen having a proximal end and a distal end, the distal end forming an obliquely-angled opening with respect to a longitudinally-oriented axis of the elongate catheter shaft; a tubular member having a proximal end and a distal end and comprising a high pressure lumen having a proximal end and a distal end, the tubular member extending within the low pressure lumen, wherein the high pressure lumen is closed at its distal end and wherein the tubular member has an opening disposed near its distal end which communicates between the high pressure lumen and the low pressure lumen, and which is in proximity to the obliquely-angled opening of the low pressure lumen; and wherein the opening of the tubular member is configured to cause fluid supplied through the high pressure lumen from a high pressure source to exit in a proximal direction from the opening of the tubular member at a high rate of speed capable of breaking thrombi within the low pressure lumen into smaller pieces when the proximal end of the low pressure lumen is coupled to a low pressure source, wherein the high pressure lumen is closed at its distal end by a plug inserted in the high pressure lumen.
