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.
