Abstract
A system for establishing differential perfusion without the use of an occlusion balloon or other flow separator devices. The flows through two lumens are controlled such that the blood flow issuing from one lumen terminating in the aortic arch supplies the entire demand of the cerebral subcirculation while the blood flow issuing from a second lumen terminating in the descending aorta supplies the entire demand of the corporeal subcirculation. When the two flows are properly balanced, an inversion layer forms therebetween and no intermixing of the two flows takes place.
