A urinary incontinence treatment apparatus comprises a restriction device (56) 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 is operable by an implantable operation device (60) to change the restriction of the urine passageway. A control device (62 and 64) is provided for controlling a source of energy, which may or may not be implanted, from outside the patient's body, to release energy for use in connection with the operation of the restriction device, i.e. to power the operation device. |
