Abstract

An extracorporeal support system including an extracorporeal support apparatus and an arterial circulation support catheter. The arterial circulation support catheter includes a blood lumen with a proximal end coupled to extracoporeal support apparatus and a distal end inserted into the blood circulation. A vent lumen has a distal end that crosses the aortic valve into the left ventricle and provides direct venting of the left ventricle through the vent lumen. An arterial circulation support catheter occluding member is positioned either in an interior or at an exterior of the arterial circulation support catheter. A venous circulation support catheter is provided and 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 included and positioned in an interior or at an exterior of the venous circulation support catheter. The venous circulation support catheter occluding member occludes the superior vena cava and the inferior vena cave

Claims

1. A method of placing a patient on cardiopulmonary bypass comprising:

introducing a catheter into a subclavian artery, the catheter including a shaft having a first lumen communicating with a first opening and a second lumen communicating with a second opening, and an expandable member attached to the shaft distal to the first opening and proximal to the second opening and being movable between a collapsed shape and an expanded shape;

endovascularly advancing the catheter from the subclavian artery to position the expandable member in the ascending aorta;

moving the expandable member into the expanded shape to occlude the ascending aorta;

infusing oxygenated blood into the arterial system downstream of the expandable member through the first lumen and the first opening; and

arresting the heart.

2. The method of claim 1 wherein the step of arresting the heart comprises delivering cardioplegic fluid upstream of the expandable member through the second lumen and the second opening.

3. The method of claim 1 further comprising removing blood from a vein of the patient through a venous cannula, oxygenating the withdrawn blood, and delivering the oxygenated blood to the arterial system through the first lumen and first opening of the catheter.

4. The method of claim 3 further comprising occluding at least one of the vena cava during the step of removing blood.
