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. |
