Patent ID: 8290594

Claim:
A male sexual impotence treatment apparatus, comprising: an operable restriction device implantable in an impotent patient for engaging a tissue portion of the normal penile tissue or the prolongation thereof to form a restrictable penile exit blood flow passageway, an energy transmission device for wireless transmission of energy from outside the patient's body to inside the patient's body for use in connection with the operation of the restriction device, including temporarily contracting said tissue portion to restrict the penile exit blood flow in the blood flow passageway to achieve erection, wherein said energy transmission device transmits energy of a first form and the restriction device is operable in response to energy of a second form, a receiving coil antenna implantable in the patient for receiving the transmitted energy, the receiving coil antenna comprising a resonant circuit comprising a capacitor and a coil, which together form the resonant circuit, the resonant circuit and the energy transmission device being tuned to the same frequency, an energy transforming device implantable in the patient for transforming the energy of the first form wirelessly transmitted by the energy transmission device into the energy of the second form, the second form of energy being electric energy, the restriction device being powered with the second form of energy both during the temporary contraction of said penile tissue portion or the prolongation thereof to achieve erection and during the release of said restriction device to release the tissue portion for releasing the penile exit blood flow in the blood flow passageway to achieve flaccid state of the penis, the operation of the restriction device being reversed when the polarity of the second form of energy is reversed, a switch implantable in the patient for directly or indirectly switching the operation of the restriction device, and a source of energy implantable in the patient, the switch being operated by the energy of the second form supplied by the energy storage device to switch from an off mode, in which the source of energy is not in use, to an on mode, in which the source of energy supplies energy for the operation of the restriction device.
