Abstract
Abstract A system for accessing a patient's cardiac anatomy which includes an endovascular aortic partitioning device that separates the coronary arteries and the heart from the rest of the patient's arterial system. The endovascular device for partitioning a patient's ascending aorta comprises a flexible shaft having a distal end, a proximal end, and a first inner lumen therebetween with an opening at the distal end. The shaft may have a preshaped distal portion with a curvature generally corresponding to the curvature of the patient's aortic arch. An expandable means, e.g. a balloon, is disposed near the distal end of the shaft proximal to the opening in the first inner lumen for occluding the ascending aorta so as to block substantially all blood flow therethrough for a plurality of cardiac cycles, while the patient is supported by cardiopulmonary bypass. The endovascular aortic partitioning device may be coupled to an arterial bypass cannula for delivering oxygenated blood to the patient's arterial system. The heart muscle or myocardium is paralyzed by the retrograde delivery of a cardioplegic fluid to the myocardium through patient's coronary sinus and coronary veins, or by antegrade delivery of cardioplegic fluid through a lumen in the endovascular aortic partitioning device to infuse cardioplegic fluid into the coronary arteries. The pulmonary trunk may be vented by withdrawing liquid from the trunk through an inner lumen of an elongated catheter. The cardiac accessing system is particularly suitable for removing the aortic valve and replacing the removed valve with a prosthetic valve.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
203 words
A method of delivering cardioplegia to a patient's heart and placing the patient on cardiopulmonary bypass, comprising the steps of: providing an aortic occlusion catheter having an occluding member, a lumen, and an outlet coupled to the lumen, the outlet being positioned distal to the occluding member, the occluding member being sized to occlude a patient's ascending aorta; passing the aortic occlusion catheter through a peripheral artery of a patient so that the occluding member is positioned in the ascending aorta; coupling the lumen to a source of cardioplegic fluid; passing cardioplegic fluid from the source of cardioplegic fluid through the lumen and out the outlet thereby stopping heart contractions; providing a coronary sinus catheter having an occluding member, a distal end, a lumen and an outlet coupled to the lumen, the occluding member being configured to occlude the patient's coronary sinus; passing the coronary sinus catheter through a peripharal vein and into the patient's right atrium; inserting the distal end of the coronary sinus catheter into the patient's coronary sinus; occluding the patient's coronary sinus with the occluding member of the coronary sinus catheter; and delivering a fluid through the coronary sinus catheter and into the patient's coronary sinus through the lumen.
