Abstract: The penile prosthesis includes proximal and distal end portions with an intermediate normally flexible, nondistensible, collapsible main body portion that adjoins the proximal and distal portions. The main body portion includes filler elements that, in some embodiments of the invention, limit radial expansion of a rigidification chamber of the main body portion, and in other embodiments, limit radial constriction of the rigidification chamber. In some embodiments of the invention, rigidification is accomplished by movement of fluid into a rigidification chamber and in other embodiments of the invention rigidification is accomplished by movement of fluid out of a rigidification chamber. The prosthesis includes a manually manipulable pumping arrangement to establish the necessary fluid movement for development of an erectile condition or a flaccid condition as desired.
