Abstract
The present invention is directed to apparatus and methods for treating a vascular occlusion by providing an infusion catheter having an atraumatic tip and at least one delivery port configured to infuse fluid into the occlusion. The fluid that is infused dilutes the occlusion and reduces adhesion of the occlusion to an intima of the vessel wall, thereby causing the occlusion to dislodge. Emboli generated in the process are directed into an emboli removal catheter for removal.
