1. A method for increasing coronary blood flow, comprising the steps of:

  • inserting a catheter into the descending aorta, the catheter having a proximal region, a distal region, and an expandable member mounted on the distal region;

    locating the expandable member in the aorta downstream from a coronary ostium;

    expanding the expandable member to partially occlude blood flow in the aorta during systole and diastole, wherein blood pressure in the proximal aorta increases, blood pressure in the distal aorta decreases, and coronary blood flow increases;

    measuring blood pressure in the proximal aorta; and

    adjusting the expansion of the expandable member based on the measured blood pressure.
