Abstract: A pump that comprises a fluid reservoir, a pump bulb, a plurality of tubing, and at least one inflatable penile cylinder. The pump comprises a pump body, an inlet valve within the pump body, an exhaust valve within the pump body and in fluid communication with the inlet valve, and a deflate valve within the pump body and in fluid communication with the inlet valve and the exhaust valve. The deflate valve enables one-touch release by (i) providing a voluntarily-activated fluid bypass so that fluid from the at least one inflatable penile cylinder can return to the fluid reservoir through at least one of the plurality of tubing without sustained activation of the deflate valve, and (ii) closing upon subsequent inflation of the at least one inflatable penile cylinder when such inflation is initiated by squeezing the pump bulb so that fluid does not flow back to the fluid reservoir.

Abstract: A pump connected to a reservoir and a cylinder of an implantable penile prosthesis includes a pump body and an inlet valve assembly. The pump body has a pump bulb connected to the pump body, where the pump bulb is operable to move fluid between the reservoir and the cylinder. The inlet valve assembly includes a valve and a tubular sleeve that provides an exit valve seat. The inlet valve assembly is disposed in an inlet channel of the pump body and operable to allow a portion of fluid to be drawn from the reservoir through the tubular sleeve and through the inlet channel to the pump bulb for delivery into the cylinder.

Abstract: Methods for manufacturing reinforced tubing suitable for medical device applications are disclosed. An inner layer is molded around a core to define an inner surface adjacent to the core and an outer surface opposite the inner surface. The outer surface includes one or more recessed pathways defined therein. A reinforcement member is then formed in each of the one or more recessed pathways of the molded inner layer. An outer layer including an inner surface and an outer surface is subsequently molded over the inner layer and the reinforcement member. The inner surface of the outer layer substantially conforms to the outer surface of the inner layer and the reinforcement member. The core is then removed from within the inner layer to provide a lumen through the inner layer.

Abstract: The invention provides mandrels for producing elastomeric components such as mammary implants. Specifically, the invention provides mandrels that include a mold, a shaft attached to the mold, and a drip retainer attached to the shaft. The drip retainers disclosed herein are configured to catch and contain fluids (e.g., elastomeric compounds dispersed in solvents) that run and/or drip off the mold and shaft, and to retain such fluids when the dipping mandrel is inverted. The invention also provides drip retainers that can catch and contain fluids (e.g., elastomeric compounds dispersed in solvents) when attached to a dipping mandrel, and can retain the fluids upon inversion of the dipping mandrel.
