1. A method of inducing cardioplegic arrest comprising:

  • forming a penetration in a wall of a left chamber of the heart;

    positioning a cardioplegia catheter through the penetration into the left chamber of the heart;

    forming a seal between the wall of the heart and the cardioplegia catheter to inhibit leakage of blood through the penetration;

    advancing a distal end of the cardioplegia catheter in the direction of blood flow from the left chamber of the heart, through the aortic valve and into the ascending aorta;

    expanding an occlusion member on the cardioplegia catheter so as to occlude the ascending aorta downstream of the coronary ostia and upstream of the brachiocephalic artery;

    delivering cardioplegic fluid through the coronary vasculature to the myocardium so as to arrest cardiac function; and

    circulating oxygenated blood in the patients arterial system downstream of the occlusion member.
