A penile prosthesis which is adapted to be surgically implanted in man for the treatment of erectile impotence includes a penile implant comprising an elongated, flexible cylindrical member having a short relatively stiff proximal portion which is adapted to be implanted into the root end of the corpus cavernosum to support the implant and an elongated flexible distal portion having a non-distensible tubular chamber substantially filled with a non-compressible fluid and a conical tip. The distal section is adapted to be implanted into the corpus cavernosum of the pendulus penis with the conical tip in the distal end of the corpus cavernosum. The prosthesis also includes means for completely filling and pressurizing the chamber to make rigid the non-distensible distal portion. In one embodiment the chamber is filled and pressurized by squeezing the chamber and reducing its volume and in another it is filled and pressurized by transferring additional fluid under pressure into the chamber.
This is a division of application Ser. No. 313,729, filed Oct. 22, 1981, now U.S. Pat. No. 4,378,792, which is a division of application Ser. No. 150,231, filed May 15, 1980, now U.S. Pat. No. 4,318,396.
The present invention is a penile prosthesis device and a non-surgical method of implantation of the device into a penis. The prosthesis device is designed to be an elastic mantle to be implanted directly into the corpus cavenosum cavity. The prosthesis device contains an elongated tube plugged at both ends and fillable with a biocompatible liquid. The liquid may be pre-filled or injected into a implanted prosthesis device to achieve the resilience and feel of the penis. The invention includes a balloon which is inserted into the corpus cavenosum cavity and a pump is used to pressurize the cavity and achieve a cylindrical expansion of the form of the penis. The invention also includes an elastic mantle having a unit including a plurality of magnets to achieve rigidity, thereby causing the penis to become erect.
A penile prosthesis for alleviating erectile impotency includes a generally tubular enclosure which is implantable within the corpus cavernosum. The tubular enclosure includes a generally non-distensible pressurizable chamber which when filled with fluid substantially to capacity will transform the prosthesis from the flaccid to an erect state, and a unique inflation valve assembly comprising two valves in longitudinally sequential relationship which will open or close under sequentially applied pressure differential conditions. The prosthesis includes a pump implantable in the body apart from the tubular enclosure, preferably in the scrotum, and a deflation valve.
A manually operable mechanical penile implant for overcoming the effects of male erectile impotence is disclosed. The implant has an elongate housing containing an elongate coil and stop means located between the two ends of the housing. Many or most of the coil turns are normally located between the stop means and the near (or proximal) end of the housing. When the device is to be used, the coil turns are drawn past the stop means toward the far (or distal) end of the housing and are locked between that end and the stop means, thereby providing rigidity (and in preferred embodiments, additional length) to the housing and therefore to the corpus cavernosum in which the device is located. In contrast to known mechanical (i.e., non-fluidic) implants, in preferred embodiments the implant may be significantly increased in length for use and significantly decreased in length after use. In contrast to fluidic devices, there is no fluid to leak or any pump or valve to be replaced in case of malfunction.
A penile prosthesis implantable within the corpus cavernosum of the penis in order to alleviate erectile impotency includes a unique deflation valve mechanism for returning the prosthesis from the erect to the flaccid state. In its preferred embodiment the prosthesis is of a unitary type comprising a distal portion including a pump, a medial portion defining a pressurizable chamber comprising an internal, tubular, substantially non-distensible portion and a concentric tubular sleeve, and a proximal portion including a fluid reservoir, the latter being in fluid communication with the pump. The deflation valve mechanism is activated in accordance with pressure differential conditions within the valve and a movable or distensible partition capable of exerting an internal force within the valve to place the valve in an open mode, thereby effecting the deflation of the prosthesis or hydraulic system in which the valve mechanism is present. Apparatus for extending the length of the prosthesis are also provided.
A sexual aid device substantially the size and shape of an adult male penis. The device has a head portion, an elongated shaft, and a base portion. The device also has an outer covering that is constructed from a resilient material to simulate the look and feel of an erect adult penis. A magnetic element is housed within the device, within its cavity. The magnet is cylindrical in shape, one piece, and extends continuously substantially from the head portion downward to the base. Since it lies below the outer covering, the magnet would never come into direct contact with any portion of the human body. The actual thickness of the outer covering should be minimized while maintaining sufficient thickness to ensure comfort for the user.
