A catheter for provides protection to the brachiocephalic and left common carotid arteries against embolic delivery associated with transcatheter aortic valve implantation (TAVI). A catheter having two lumens is introduced into the radial artery and the distal end is delivered to the aorta and an intermediate end is delivered to the brachiocephalic artery. Blood is taken from the aorta and is delivered to the intermediate end via a pump. Fluid flow out of the brachiocephalic artery prevents embolic debris from entering the brachiocephalic artery streamlines of blood flow into the aorta prevent embolic debris from entering the neighboring left common carotid artery.
