Patent ID: 8152782

Claim:
A system for endoluminal aspiration of embolic material, the system having a proximal end, a distal end and a longitudinal axis extending therebetween, the system comprising: a guidewire having a proximal end and a distal end; and an aspiration catheter system having a proximal end and a distal end and having an aspiration lumen in fluid communication with a source of suction, an infusion lumen in fluid communication with a source of infusion fluid, a guidewire lumen adapted to receive the guidewire, wherein the aspiration lumen has a distal end and a first port at the aspiration lumen distal end, and wherein the infusion lumen has a distal end and a first port proximate the infusion lumen distal end, wherein the infusion lumen distal port faces generally radially with respect to the longitudinal axis, wherein the aspiration lumen distal port is distal the infusion lumen distal port, and wherein there are no intervening ports between the aspiration lumen distal port and the infusion lumen distal port, wherein the aspiration lumen and the infusion lumen are non-coaxial, and wherein the aspiration lumen distal port is an aspiration port at the aspiration catheter system distal end.
