Abstract
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.
