Abstract
A penile prosthesis includes a rotary pump for pressurizing a bag or chamber within the penis. The rotary pump includes a magnetically active rotor which, in one embodiment, is located within the penis, which can be made to spin by a rotary magnetic field generator. The rotary magnetic field generator may be similar to those used in conjunction with brushless DC motors, or it may be a permanent magnet spun about an axis. In operation of one embodiment, the magnetic field generator surrounds the penis at a location near the rotor. The rotor drives an impeller or blades which pressurize fluid from a reservoir, and tends to pressurize the bag or chamber to thereby render the penis rigid. A valve arrangement prevents loss of pressure when the rotating field is removed. In one embodiment, the valve arrangement includes a spring-operated check valve in conjunction with another valve, and in another embodiment, a single centrifugally-operated valve performs the same function. Other embodiments locate the rotary pump under the skin in the retropubic region or the scrotum, at locations at which a rotary magnetic field generator can rotate the pump rotor.
