Abstract:
1. A urinary incontinence treatment apparatus, comprising: a restriction device implantable in a patient for engaging the urethra or urine bladder to form a restricted urine passageway in the urethra or urine bladder, the restriction device being operable to change the restriction of the urine passageway, an internal source of energy implantable in the patient, a control device operable from outside the patient's body for controlling the internal source of energy to release energy-the operation of the restriction device, an external source of energy intended to be external to the patient's body when the restriction device is implanted in a patient, the external source of energy being adapted to release wireless energy, and an energy transforming device implantable in the patient's body for transforming the wireless energy released from the external source of energy into storable energy, the internal source of energy being capable of storing the storable energy, and the control device being comprised of an external control unit operable from outside the patient's body for providing a signal, and an internal control unit implantable in the patient's body and adapted to control the restriction device in response to the signal, the control device being activated in a manual manner or non-manual manner to control the source of energy to release energy, the apparatus further comprising implantable electrical components including a single voltage level guard and an implantable capacitor or accumulator, the charge and discharge of the capacitor or accumulator being controlled by use of the voltage level guard.
