VASCULAR GRAFT AND BLOOD SUPPLY METHOD

摘要

A graft is used to supply blood to one or more coronary artery branches. 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 located remote from the inlet end of the tubular body. The pressure differential between the blood supply and blood receiver maintains continuous and adequate blood flow at a desired pressure in the body passage and provides a continual supply of blood for the coronary artery branches.
