Claim:
1. A debris deflector comprising: an elongate support member and a porous deflection structure adapted to lie substantially along a longitudinal segment of an aortic arch while extending transversely about less than an entire circumference of the aorta, wherein the porous deflection structure comprises a single panel blood permeable membrane and a support structure, wherein the single panel blood permeable membrane of the porous deflection structure further includes a plurality of projections which provide a trapping texture extending substantially perpendicular to the support surface of the single panel blood permeable membrane, wherein the support structure comprises a central spine and a plurality of laterally extending branches, wherein the plurality of laterally extending branches of the support structure are biased to assume a configuration which is convex toward the wall of the aorta proximate the brachiocephalic artery, the right common carotid artery, and the left common carotid artery and further wherein the central spine of the support structure is convex along the wall of the aorta proximate the brachiocephalic artery and the left common carotid artery, wherein the elongate support member and porous deflection structure are adapted to be delivered to an aorta via the left subclavian artery and to deploy generally upstream therefrom to cover the ostium of the brachiocephalic artery, the ostium of the right common carotid artery, the ostium of the left common carotid artery, and at least a portion of the ostium of the left subclavian artery.
