Abstract
A valve is included as part of a medical appliance used to transport an artificial blood vessel into a body through a catheter. The valve is formed by a membrane having a plurality of holes which are normally closed and which can be pushed to open against elasticity of the membrane to permit a plurality of devices used to transport the artificial blood vessel to be passed through the holes in parallel with each other. In a preferred embodiment, a hole is provided at the center of the membrane and three other holes are equi-spaced from the center hole; equal spaces are also provided between adjacent ones of the three holes. A relatively thick embankment or projecting portion is preferably provided extending between every pair of adjacent holes, to avoid breakage of the membrane therebetween upon parallel insertion of devices through the holes.
