Systems and methods for thrombolysis and drug delivery

摘要

A system for thrombus aspiration and drug delivery includes a supply lumen having a proximal end, a distal end and a wall, and an aspiration lumen having an inner wall adjacent the proximal end, an open distal end and the open distal end. An aspiration catheter, and at least one orifice in fluid communication with the aspiration lumen at or adjacent the distal end of the supply lumen and disposed proximal to the open distal end of the aspiration lumen Wherein the at least one orifice is configured to create a spray pattern that impinges on the inner wall surface of the aspiration lumen, and the spray pattern that impinges on the inner wall surface is capable of exiting the open distal end of the aspiration lumen It is adapted to be converted into a flow at least approximately in the distal direction.
