The present invention comprises a pulmonary valved conduit that permits inflow diameters greater than about 22 mm while still maintaining the advantages of a naturally-formed biological valved conduit. Specifically, the present invention comprises a valved vascular prosthetic having an inflow conduit comprising a manifold formed from the sealed attachment of at least two venous valvular conduits.

Bifurcated biological pulmonary valved conduit

Exovascular and endovascular stent devices and associated support/restrictor assemblies for use in conjunction with prosthetic vascular grafts, including venous valve grafts made from preserved bioprosthetic venous valves. Also disclosed are methods for preparing vascular grafts such as venous valve grafts using the devices and assemblies of the present invention.

Stent devices and support/restrictor assemblies for use in conjunction

A biological valvular prosthesis defined by a chemically fixed biological derived conduit having at least one integrally formed tissue valve. The chemical fixation of the valve ensures that the leaflets remain open under normal forward blood flow conditions, but close under minimal backflow pressure. The biological valvular prostheses are useful in the replacement of venous valves and other biological valves. The biological valvular prosthesis may also be in the form of a tubular conduit bearing one tissue valve. This valvular conduit prosthesis is useful for the reconstruction of the pulmonary artery to correct various types of congenital defects.
