A heartburn and reflux disease treatment apparatus comprises an adjustable restriction device (234) implanted in a patient engaging the stomach close to the cardia, or alternatively engaging the esophagus (206), to form a restricted food passageway in the stomach or esophagus. An adjustment device is implanted in the patient for adjusting the restriction device to restrict and enlarge the passageway, and a hydraulic operation means (236) is implanted in the patient for operating the adjustment device. By using a wireless remote control (238) the patient can control the hydraulic operation means, whereby the restriction device works like an artificial sphincter.
