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 said first form 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 adapted to be implanted in the patient for transferring energy of the first form transmitted by said energy transmission device into energy of the second form, wherein said energy transfer device comprises at least one element having a positive region and a negative region, and creating an energy field between said positive and negative regions when exposed to the first form energy transmitted by said energy transmission device, so that said energy field produces the energy of the second form.

Abstract
A heartburn and reflux disease treatment apparatus and method include or use an operable restriction device implanted in a patient and engaging the stomach close to the cardia or engaging the esophagus to form a restricted passageway. An energy transmission device for wireless transmission of energy of a first form from outside the patient'"'"'s body is provided. An implanted energy transfer device transfers the energy of the first form transmitted by the energy transmission device into energy of a second form, which is used to control the operation of the restriction device to vary the size of the restricted passageway. The energy transfer device includes at least one element having a positive region and a negative region, the element being capable of creating an energy field between the positive and negative regions when exposed to the first form energy transmitted by the energy transmission device, so that the energy field provides the second form energy.
