Abstract: A system for aspirating thrombus and delivering an agent including an aspiration catheter having an aspiration lumen and a supply lumen, and at least one orifice at or adjacent a distal end of the supply lumen and in fluid communication with the aspiration lumen, the at least one orifice located proximally of the open distal end of the aspiration lumen, wherein the at least one orifice is configured to create a spray pattern when pressurized fluid is pumped through the supply lumen such that the spray pattern is caused to impinge on a deflection element disposed opposite the at least one orifice when a distal end of the aspiration catheter is immersed within an aqueous environment, and such that the spray pattern upon impinging on the deflecting elements is caused to deflect, transforming into at least a substantially distally-oriented flow configured to exit the open distal end of the aspiration lumen.
