A pump with a one-touch release for an inflatable penile prosthesis, the inflatable penile prosthesis comprising a fluid reservoir, a plurality of tubing (6, 7a, 7b), and at least one inflatable penile cylinder (5a, 5b), said pump with a one-touch release comprising: - a pump body and a pump bulb; - an inlet valve within said pump body adapted to be in fluid communication with the fluid reservoir via inlet tubing providing a fluid conduit between reservoir and pump; - an exhaust valve within said pump body and in fluid communication with said inlet valve and adapted to be in fluid communication with said at least one cylinder (5a, 5b) via exhaust tubing (7a, 7b) providing a fluid conduit between pump and cylinder (5a, 5b), said inlet and exhaust valves (11, 12) being located between the bulb and said inlet and exhaust tubing (6, 7a, 7b) so that when the bulb is squeezed, fluid is transferred between the fluid reservoir and the penile cylinder (5a, 5b); and - a deflate valve within said pump body and in fluid communication with said inlet valve and said exhaust valve, characterized in that said deflate valve enables one-touch release by (i) providing, upon activation of said deflate valve into an open state by a user, a user-activated fluid bypass so that fluid from said at least one inflatable penile cylinder (5a, 5b) can return to said fluid reservoir through at least one of said plurality of tubing (6, 7a, 7b) without sustained activation of said deflate valve by the user, said deflate valve comprising a restriction means (317, 341) for maintaining said deflate valve in an open state, and (ii) said deflate valve being adapted to close upon subsequent inflation of said at least one inflatable penile cylinder (5a, 5b) when such inflation is initiated by squeezing said pump bulb, so that fluid does not flow back to said fluid reservoir. - a pump body and a pump bulb; - an inlet valve within said pump body adapted to be in fluid communication with the fluid reservoir via inlet tubing providing a fluid conduit between reservoir and pump; - an exhaust valve within said pump body and in fluid communication with said inlet valve and adapted to be in fluid communication with said at least one cylinder (5a, 5b) via exhaust tubing (7a, 7b) providing a fluid conduit between pump and cylinder (5a, 5b), said inlet and exhaust valves (11, 12) being located between the bulb and said inlet and exhaust tubing (6, 7a, 7b) so that when the bulb is squeezed, fluid is transferred between the fluid reservoir and the penile cylinder (5a, 5b); and - a deflate valve within said pump body and in fluid communication with said inlet valve and said exhaust valve, characterized in that said deflate valve enables one-touch release by (i) providing, upon activation of said deflate valve into an open state by a user, a user-activated fluid bypass so that fluid from said at least one inflatable penile cylinder (5a, 5b) can return to said fluid reservoir through at least one of said plurality of tubing (6, 7a, 7b) without sustained activation of said deflate valve by the user, said deflate valve comprising a restriction means (317, 341) for maintaining said deflate valve in an open state, and (ii) said deflate valve being adapted to close upon subsequent inflation of said at least one inflatable penile cylinder (5a, 5b) when such inflation is initiated by squeezing said pump bulb, so that fluid does not flow back to said fluid reservoir. (i) providing, upon activation of said deflate valve into an open state by a user, a user-activated fluid bypass so that fluid from said at least one inflatable penile cylinder (5a, 5b) can return to said fluid reservoir through at least one of said plurality of tubing (6, 7a, 7b) without sustained activation of said deflate valve by the user, said deflate valve comprising a restriction means (317, 341) for maintaining said deflate valve in an open state, and (ii) said deflate valve being adapted to close upon subsequent inflation of said at least one inflatable penile cylinder (5a, 5b) when such inflation is initiated by squeezing said pump bulb, so that fluid does not flow back to said fluid reservoir.
