Abstract: The prosthesis comprises a flexible rod, surrounded along approximately two-thirds of its length by an inflatable balloon, which is implanted centrally within the two corpora cavernosa of the penis and replacing the function of same. To supply fluid to the inflatable balloon there is a reservoir that is implanted within the scrotal sac of the patient. Located in a tube between the reservoir and the balloon portion of the implant is a pinch valve for maintaining the fluid within either the balloon portion or the reservoir under the control of the patient. To effect erection of the penis, the pinch valve is pinched while the reservoir is squeezed, forcing the hydraulic fluid into the balloon portion of the implant. When it is desired to depressurize the implant, the pinch valve is again pinched and the fluid under pressure will then return to the unpressurized reservoir.

Abstract: A dental implant includes a porous ceramic cup or ring filled with silicone rubber which supports an artificial tooth or other prosthetic device such as a denture. The jawbone grows into the porous ceramic to hold the implant firmly in place. The silicone rubber cushions the jawbone from shock caused by multidirectional masticatory forces. A fibrous matting is partially embedded into the upper periphery of the silicone rubber that extends from the ceramic cup or ring. Gingival tissue becomes attached to the matting to form a seal that precludes bacteria from invading and infecting the implant area. In another embodiment, the implant includes a metal sleeve completely filled with and surrounded by silicone rubber. Fibrous matting is partially embedded into the surface of the silicone rubber. Both the jawbone and the gingival tissue adhere to the matting to hold the implant firmly in place and to prevent bacterial invasion.
