A system for accessing a patient\s cardiac anatomy which includes an occlusion catheter with a first expandable member or balloon in a distal extremity of the catheter which when expanded within the patient\s ascending aorta separates the heart and coronary blood vessels from the rest of the patient\s arterial system, and a second expandable member, distal to the first, which when expanded will be seated within the left ventricle. A cardiopulmonary bypass system is connected to a major vein, e.g. femoral, to withdraw blood, remove carbon dioxide, oxygenate the withdrawn blood and then return the oxygenated blood to the patient\s arterial system through a major artery. Preferably, the heart muscle or myocardium is paralyzed by the antegrade and/or retrograde delivery of a liquid containing cardioplegic material to the myocardium through patient\s coronary arteries or coronary sinus. The cardiac accessing system is suitable for a wide variety of cardiac procedures including opened and closed chest procedures.

An endovascular intra-aortic catheter system for providing access to a patient\s heart through an aortic passageway leading away from an aortic valve in the patient\s heart while isolating the heart from the patient\s arterial system, comprising: a) an elongated catheter shaft which is advanceable through the aortic passageway leading away from the aortic valve of the patient\s heart, which has a proximal portion adapted to extend out of the patient and a distal portion adapted to be disposed within the patient\s ascending aorta and left ventricle, and which has a first inner lumen extending therein from a port in the distal portion of the catheter shaft to a location in the proximal portion; b) a first expandable member on the distal portion of the catheter shaft spaced proximally from the port in the distal portion which is dimensioned and configured so that it occludes the aortic passageway within the ascending aorta when expanded; and c) a second expandable member on the distal portion of the catheter shaft located proximally of the port in the distal portion and distally to the first expandable means and which is dimensioned and configured so that it seats within the left ventricle when expanded to secure the catheter as to minimize catheter movement within the aortic passageway, wherein said first and second expandable members are spaced-apart from each other by a distance sufficient to permit positioning in the aortic passageway and the left ventricle, respectively.
