A shunt and method of use for maintaining distal blood flow during an arteriotomy procedure is disclosed. The shunt includes a first tubular member (10) having a proximal end adapted to receive blood from a first region of an artery. A distal end is adapted to release blood into a second region of the artery. The shunt includes a second tubular member (14) having a lumen which either merges and communicates at its distal end with a lumen of the first tubular member, or rides separate and parallel to it. The shunt is secured to the lumen of the artery. A blood filter device (41, 42) is deployed within the artery. The proximal opening of the shunt is inserted into the first region of the artery, and secured to the lumen of the artery. Endarterectomy is performed on the artery and embolic material dislodged during the procedure is captured by the filter.
L'invention a trait à un shunt, ainsi qu'à sa technique d'utilisation, permettant de maintenir le débit sanguin distal durant une artériotomie. Le shunt comporte un premier élément tubulaire (10) dont l'extrémité proximale est conçue pour recevoir du sang en provenance d'une première région d'une artère, l'extrémité distale étant conçue, quant à elle, pour apporter du sang à une seconde région de l'artère. Ce shunt comporte également un second élément tubulaire (14) pourvu d'une lumière qui, soit fusionne et communique sur son extrémité distale avec une lumière du premier élément tubulaire, soit décrit un parcours distinct mais parallèle. Le shunt est fixé à la lumière de l'artère. Un dispositif de filtration du sang (41, 42) est déployé dans l'artère. L'ouverture proximale du shunt est insérée dans la première région de l'artère et fixée à la lumière de celle-ci. Le matériau embolique détaché durant l'endartériectomie est arrêté par le filtre.
