ABSTRACT:
A valve for an inflatable prosthesis of the type which comprises a fluid-containing envelope with an aperture closed by a valve through which a desired amount of fluid can be filled or withdrawn. The valve comprises a flat elongated conduit having a pair of sealed edges, and between said edges a pair of flat flexible wall members facing each other to form a fluid seal when they bear against one another. The conduit is open at one end. At the other end it is closed except for a slit formed in one of the walls without removal of material. The valve tends to remain closed both as a consequence of inherent closure of the slit and also as a consequence of pressure of the walls against one another.
