1. A heartburn and reflux disease treatment apparatus, comprising:

  • an energy transmission device for wireless transmission of energy of a first form from outside a patient'"'"'s body;

    an operable restriction device adapted to be implanted in a patient having heartburn and reflux disease to engage the esophagus or the stomach close to the cardia without forming an upper pouch of the stomach that substantially accumulates food to form a restricted passageway in the stomach or esophagus, said restriction device being designed to work like an artificial sphincter to allow food to readily pass through the passageway and operable in response to a second energy form different than the first form energy to restrict the passageway sufficiently so as to substantially prevent regurgitation of stomach acids or foods into the patient'"'"'s esophagus; and

    an energy transfer device implantable in the patient for transferring energy of the first form transmitted by said energy transmission device into energy of the second form, to operate said restriction device.
