Abstract

Implantable integral device (20) and corresponding method for deflecting embolic material in blood flowing (60) at an arterial bifurcation (52), featuring an expandable dual diameter coil element (21) having a contracted state with a first diameter in which there is at least partial overlap of two opposing ends of the coil element, and an expanded state having a second diameter greater than the first diameter, wherein a portion (27), of and integral with the coil element 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. The portion (27) of the coil element (21) is a finely meshed zone functioning as a deflecting and filtering element, for deflecting the embolic material in the flowing blood while filtering the flowing blood.
