  • providing a catheter having a proximal end, a distal end, and an expandable member mounted on the distal end, and a lumen extending from the proximal end and communicating with a port distal the expandable member;

    advancing the distal end of the catheter into the descending aorta;

    locating the expandable member downstream from the takeoff of a carotid artery; and

    expanding the expandable member to at least partially obstruct blood flow in the aorta during systole and diastole, wherein blood pressure in the proximal aorta is altered.
