A heartburn and reflux disease treatment apparatus comprises a restriction device (56) implantable in a patient for engaging the stomach close to the cardia or, which is preferred, engaging the esophagus (58) to form a restricted food passageway in the stomach or esophagus. The restriction device is operable by an implantable operation device (60) to change the restriction of the food 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. |
