Abstract:
1. An urinary incontinence disease treatment apparatus for treatment of a patient, who suffers from urinary incontinence, comprising a restriction device implantable in the patient for engaging the urethra or urinary bladder to form a restricted urine passageway therein, the restriction device being operable to change the restriction of the urinary passageway, an operation device implantable in the patient for operating the restriction device, 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 powering the operation device, and an energy transforming device implantable in the patient for transforming the energy of the first form wirelessly transmitted by the energy transmission device into energy of a second form different than the energy of the first form, the restriction device being operable in response to the energy of the second form to change the restriction of the urinary passageway, when the restriction device is implanted, wherein the operation device comprises: (i) a motor implantable in the patient, wherein the energy of the second form is used for powering the motor to operate the restriction device; or (ii) a pump implantable in the patient, wherein the energy of the second form is used for reversibly powering the pump to operate the restriction device, and wherein the apparatus further comprises a receiving coil antenna for receiving said transmitted energy, said receiving coil antenna comprises a resonant circuit comprising a capacitor and a coil, which together form said resonant circuit tuned to the same frequency as the energy transmission device, and wherein the apparatus further comprises at least one implantable voltage level guard.
