Abstract
A thrombectomy catheter system is disclosed which includes a catheter having an exhaust lumen, an infusion lumen and a high pressure tube. The high pressure tube includes a nozzle orifice for forming a high pressure jet of fluid for cutting occlusive material from within a body lumen. The nozzle orifice is positioned to direct the high pressure jet of fluid into the distal end of the exhaust lumen which creates a suctioning effect. The infusion lumen replaces fluid that is removed from the body lumen through the exhaust lumen by a suctioning effect created by the fluid jet.
