1. A method for performing an endovascular procedure on a patient, the method comprising steps of:

  • a) placing an elongated aortic occlusion catheter at a location within the patient'"'"'s ascending aorta, the aortic occlusion catheter having a proximal end, a distal end, and an expandable member, the expandable member of the aortic occlusion catheter being movable to an expanded shape which is sized and configured to substantially occlude a passageway in the patient'"'"'s ascending aorta downstream of the ostia of the coronary arteries, the aortic occlusion catheter also including a lumen having an outlet;

    b) expanding the expandable member of the aortic occlusion catheter within the patient'"'"'s ascending aorta to substantially completely occlude the passageway therein downstream of the ostia of the patient'"'"'s coronary arteries and without occluding said ostia thereby blocking blood flow through the aorta;

    c) placing a coronary catheter having a proximal end, a distal end and an expandable member through the lumen of the aortic occlusion catheter until the distal end of the coronary catheter exits the lumen of the aortic occlusion catheter;

    d) directing the coronary catheter into one of the patient'"'"'s coronary arteries; and

    e) expanding the expandable member of the coronary catheter within the patient'"'"'s coronary artery.
