CA 2054728

A biological valvular prosthesis (10) defined by a chemically fixed biological derived conduit (12) having at least one integ- rally formed tissue valve (14). The chemical fixation of the valve ensures that the leaflets (16), (18) remain open under normal for- ward blood flow conditions, but close under minimal backflow pressure. The biological valvular prostheses are useful in the re- placement of venous valves and other biological valves. The biological valvular prosthesis may also be in the form of a tubular conduit bearing on tissue valve.
