Abstract
A graft is used to supply blood to one or more coronary artery branches. The graft is also usable as a peripheral revascularization and inter position prosthesis to supply blood to desired blood vessels. The graft has an elongated U-shaped tubular body providing a continuous passage for carrying blood from a high pressure blood supply to a blood receiver. One or more openings in the body allow blood to flow into the coronary artery branches. The flow and pressure of the blood in the passage is controlled by a restriction providing a restricted passage located remote from the inlet end of the tubular body. In one embodiment, the restriction is reinforced with a sleeve to maintain a desired cross sectional area and length of the restricted passage. The pressure differential between the blood supply and blood receiver maintains continuous and adequate blood flow at a desired pressure in the continuous passage and provides a continual supply of blood for the coronary artery branches.
