Abstract

A system for providing total isolation of the heart includes an extracorporeal support apparatus. An arterial circulation support catheter is provided having a blood lumen with a proximal end coupled to the extracorporeal support apparatus and a distal end positioned in the aortic root and a left side of the heart. An arterial circulation support catheter occluding member is coupled to the arterial circulation support catheter. The arterial circulation support catheter occluding member is positioned to prevent blood flow into the left ventricle or left side of the heart. A venous circulation support catheter includes a blood lumen with a proximal end coupled to the extracorporeal support apparatus, and a distal end inserted into the blood circulation A venous circulation support catheter occluding member is coupled to the venous circulation support catheter and positioned between the superior vena cava and the inferior vena cava. This positioning occludes the superior and inferior vena cava and prevents blood from flowing into the right atrium or a right side of the heart.

Claims

1. A method of occluding a patient'"'"'s ascending aorta, delivering oxygenated blood and delivering a cardioactive agent, comprising the steps of:

providing an arterial catheter having a blood flow lumen;

coupling the blood flow lumen of the arterial catheter to a source of oxygenated blood;

inserting the arterial catheter into the patient'"'"'s ascending aorta through a penetration in the patient'"'"'s aortic arch;

passing an aortic occlusion catheter through the arterial catheter, the aortic occlusion catheter having a cardioplege lumen and an occluding member movable from a collapsed shape to an expanded shape;

slidably moving the aortic occlusion catheter relative to the arterial catheter thereby positioning the occluding member in the patient'"'"'s ascending aorta;

occluding the patient'"'"'s ascending aorta by moving the occluding member from the collapsed shape to the expanded shape;

delivering oxygenated blood to the patient through the blood flow lumen; and

infusing a cardioactive agent through the cardioplege lumen in the aortic occlusion catheter.

3. The method of claim 1, further comprising the step of:

venting the patient'"'"'s left ventricle.

4. The method of claim 3, wherein:

the venting step is carried out with the aortic occlusion catheter, the aortic occlusion catheter extending through the patient'"'"'s aortic valve and into the left ventricle, the aortic occlusion catheter having openings therein for venting the left ventricle.

2. The method of claim l,wherein:

the providing step is carried out with the arterial catheter having another lumen; and

the passing step is carried out with the catheter passing through the another lumen of the arterial catheter.
