Abstract:
A method for protecting a patient against cerebral embolization, said method comprising the steps of:providing an aortic diverter comprising an elongate tube having a wall impermeable to emboli, the tube having a proximal end terminating in a substantially circular edge adapted to fill the lumen of the aorta, and a distal end, wherein the proximal and distal ends are substantially open allowing blood to enter the proximal end, flow through the tube, and exit the distal end; inserting the aortic diverter in the aortic arch; and positioning the aortic diverter so that the proximal end of the aortic diverter is upstream of the brachiocephalic trunk and the distal end of the aortic diverter is downstream of the left subclavian artery or the left brachiocephalic trunk, wherein emboli passing through the aortic arch flow through the aortic diverter and are diverted from the carotid arteries to the peripheral vasculature.
