A system for accessing a patient's cardiac anatomy which includes an occlusion catheter (10) with a first expandable member (11) or balloon on 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 (15), distal to the first, which when expanded will be seated within the left ventricle. A cardiopulmonary bypass system (18) is connected to a major vein, e.g., femoral (20), to withdraw blood, remove carbon dioxide, oxygenate the withdrawn blood, and then return the oxygenated blood to the patient's arterial system through a major artery (22). Preferably, the heart muscle or myocardium is paralyzed by the antegrade and/or retrograde delivery of a liquid containig 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.

Système permettant d'accéder à l'ensemble d'anatomie cardiaque d'un patient et comportant un cathéter d'occlusion (10), muni, en son extrémité distale, d'un premier élément dilatable (11), ou d'un ballonnet fixé à l'extrémité distale qui, lorsqu'il est gonflé dans l'aorte ascendante, isole les vaisseaux sanguins cardiaques et coronaires du reste du système artériel du patient, et un second élément dilatable (11) disposé en amont du premier qui, une fois gonflé, se place dans le ventricule gauche. Un système de dérivation cardio-pulmonaire (18) relié à une veine majeure telle que la veine fémorale (20) permet de prélever le sang, d'en extraire le CO¿2?, de l'oxygéner et de le renvoyer dans le système artériel par une artère majeure (22). Le myocarde ou le muscle cardiaque est, de préférence, paralysé par un apport antérograde ou rétrograde de liquide cardioplégique dans les artères ou les sinus coronaires. Ledit système est compatible avec une grande variétés d'interventions cardiaques à thorax ouvert ou fermé.
