Abstract:
A vascular prosthetic suitable for replacing a patient's damaged or missing pulmonary valve, said prosthetic comprising:an inflow conduit comprising a manifold formed from the sealed attachment of a plurality of donor valved blood vessels, each of said blood vessels housing a biological valve integral therewith, said blood vessels configured to permit the flow of blood therethrough by the valve opening at a relatively low pressure and configured to prevent the backflow of blood therethrough by the valve closing so as to withstand relatively high pressures, said manifold formed upstream of each of the biological valves so as not to interfere with the effective operation of the biological valves, said inflow conduit having a resulting flow capacity following sealed attachment that is larger than the original flow capacity of each of the donor blood vessels, andan outflow conduit positioned downstream of each of the biological valves.
