CA 2648905

The present invention is directed to apparatus and methods for treating a vascular occlusion by providing an infusion catheter (10) having an atraumatic tip (12) and at least one delivery port (14) 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 (60) for removal.

La présente invention porte sur un appareil et des méthodes permettant de traiter une occlusion vasculaire à l'aide d'un cathéter destiné à la perfusion (10), muni d'une extrémité atraumatique (12) et au moins un orifice de distribution (14) configuré pour perfuser un liquide dans une embole. Le liquide perfusé dilue l'embole et réduit l'adhérence de celle-ci à l'intima de la paroi vasculaire, ce qui déloge le caillot. L'embole libérée est alors dirigée dans un cathéter (60) destiné à son élimination.
