Abstract:
1. A thrombectomy catheter comprising: a catheter body extending from a catheter distal portion toward a catheter proximal portion, the catheter body including a catheter lumen; a high pressure tube extending through the catheter lumen from the catheter proximal portion toward the catheter distal portion, the high pressure tube in communication with a fluid source near the catheter proximal portion; a multidirectional fluid jet emanator in communication with the high pressure tube, the multidirectional fluid jet emanator having at least one jet orifice for directing at least one first high velocity fluid jet from said multidirectional fluid jet emanator in a first direction and at least one jet orifice for directing at least one second high velocity fluid jet from said multidirectional fluid jet emanator in a second direction; an outflow orifice positioned at a first discrete location along a perimeter of the catheter distal portion, wherein the outflow orifice is configured to generate a jet stream out of the catheter body with the at least one first high velocity fluid jet; an entrainment inflow orifice positioned at a second discrete location on the perimeter of the catheter distal portion, wherein the entrainment inflow orifice is configured to receive a jet stream first portion and direct the jet stream first portion toward the outflow orifice in combination with the at least one first high velocity fluid jet; and an evacuation inflow orifice positioned at a third discrete location on the perimeter of the catheter distal portion, wherein the evacuation inflow orifice is configured to receive a jet stream second portion and direct the jet stream second portion in combination with the at least one second high velocity fluid jet toward the catheter proximal portion, wherein the evacuation inflow orifice is separate from the entrainment inflow orifice.
