Abstract: A method and apparatus for providing circulation to distal organs and blood flow for intercostal lumbar perfusion during aortic surgery by means of an intercostal and lumbar perfusion shunt having a main tubular member defining a first flow path and a plurality of side tubular members connected intermediate the ends of the main tubular member and defining a plurality of second flow paths. The method includes the steps of shunting a pathologic section by connecting the free ends of the main tubular member to the aorta proximal and distal to the pathology for providing blood flow to the distal organs and by connecting the free ends of the side tubular members to the intercostals through an opening in the aorta for providing blood flow to the intercostals during surgery.
