Enhanced Cross Stream Mechanical Thrombectomy Catheter

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 fluid jet emanator having at least one jet orifice for directing at least one first high velocity fluid jet from said fluid jet emanator in one direction and at least one jet orifice for directing at least one second high velocity fluid jet from said fluid jet emanator in another direction;
• an outflow orifice configured to generate a jet stream out of the catheter body with the fluid jet, the outflow orifice is located at a discrete location along the catheter perimeter of the catheter distal portion;
• an entrainment inflow orifice positioned along the catheter perimeter of the catheter distal portion, 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 first high velocity fluid jet;
• and
• an exhaust inflow orifice positioned along the catheter perimeter of the catheter distal portion, the exhaust inflow orifice is configured to receive a jet stream second portion and direct the jet stream second portion in combination with the second high velocity fluid jet toward the catheter proximal portion, wherein the exhaust inflow orifice is separate from the entrainment inflow orifice.
