CA 2483264

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 concerne un appareil et des méthodes de traitement d'une occlusion vasculaire par utilisation d'un cathéter d'infusion présentant une pointe atraumatique et au moins un orifice de distribution conçu pour infuser un fluide dans l'occlusion. Le fluide infusé dilue l'occlusion et réduit l'adhérence de l'occlusion sur une intima de la paroi vasculaire, entraînant ainsi le délogement de l'occlusion. Les embolies générées au cours du procédé sont dirigées dans un cathéter de retrait d'embolies pour être retirées.
