Inflatable penile prosthesis with satellite reservoir

Claim 1

An implantable penile prostheses comprising: 1) a generally tubular body implantable within one or each of the corpus cavernosa of the penis to simulate a natural erection; and 2) a fluid reservoir implantable in a patient's body in fluid communication with said tubular body; said tubular body comprising: a generally tubular chamber inflatable from a flaccid to an erect state when filled with a fluid substantially to capacity and deflatable from the erect state to the flaccid state when substantially free of fluid, said tubular chamber being in fluid communication with said fluid reservoir through a second passageway which is defined by a conduit extending axially along the length of said tubular body externally of said tubular chamber; a manually actuatable valve system for controlling fluid flow between said tubular chamber and said fluid reservoir; and a proximal section and a distal section; said valve system comprising a first valve for controlling fluid flow from said tubular chamber to said fluid reservoir to attain the flaccid state, and a pump and a second valve to allow an irreversible fluid flow from said fluid reservoir to said tubular chamber to attain the erect state on compressing said pump, said pump located in said distal section and said second valve located in said proximal section, both of said pump and said second valve being in series with said tubular chamber along the length of said tubular body, said pump and said second valve being in fluid communication through a first passageway which is in fluid isolation from said second passageway defined by a conduit extending axially along the length of said tubular body externally of said tubular chamber.
