Abstract

A method and device for occluding a patient'"'"'s ascending aorta, maintaining circulation of oxygenated blood in the patient and delivering cardioplegic fluid to arrest the patient'"'"'s heart. An aortic occlusion catheter has an occluding member for occluding the ascending aorta. The aortic occlusion catheter passes through a cannula. Delivery of oxygenated blood is accomplished through either the cannula or the aortic occlusion catheter.

Claims

1. A system for occluding a patient'"'"'s ascending aorta and delivering oxygenated blood to the patient, comprising:

a cannula having a first lumen and a second lumen, the first lumen having a distal end for delivering oxygenated blood;

an occluding member mounted to one side of the cannula at a location proximal the distal end, the occluding member being movable between a collapsed position and an expanded position, the occluding member having a pathway therethrough in fluid communication with the second lumen, wherein the occluding member is a balloon.

2. The system of claim 1, wherein the occluding member is configured to occlude the aorta at a location between the barchiocephalic arteries and the coronary ostia.

3. The system of claim 2, wherein the occluding member is configured such that the cannula is located between the occluding member and the brachiocephalic arteries when the occluding member occludes the aorta at a location between the brachiocephalic arteries and the coronary ostia.

4. The system of claim 1, wherein the cannula has a third lumen in fluid communication with the interior of the occluding member.

5. The system of claim 4, comprising a source of cardioplegia fluid coupled to the second lumen.

6. The system of claim 1, comprising a source of oxygenated blood coupled to the first lumen.

7. The system of claim 1, wherein the distal end of the cannula has side ports.
