IMPLANTABLE COMPOSITE DEVICE AND CORRESPONDING METHOD FOR DEFLECTING EMBOLIC MATERIAL IN BLOOD FLOWING AT AN ARTERIAL BIFURCATION

摘要

Implantable composite device and corresponding method for deflecting embolic material (60) in blood (80) flowing at an arterial bifurcation (52), featuring a deflecting and filtering element (27), and, a separate basis element (20) for supporting the deflecting and filtering element and for anchoring the device at the arterial bifurcation, whereby an operative composite of the deflecting and filtering element and the basis element forms the composite device having a contracted state with a first diameter and an expanded state having a second diameter greater than the first diameter, wherein the deflecting and filtering element (27) deflects the embolic material in the blood flowing toward a first branch (40) of the arterial bifurcation into a second branch (42) of the arterial bifurcation, while filtering the blood flowing toward the first branch of the arterial bifurcation. Deflecting and filtering element (27) is of finely meshed material, for effectively deflecting and filtering.
