A food intake restriction apparatus and method for an obese patient includes and uses an energy transmission device for wireless transmission of energy of a first form from outside the patient's body. An operable restriction device is implanted in the patient and engages the stomach or the esophagus to form an upper small pouch of the stomach, and a restricted stoma opening is formed in the stomach or esophagus. The restriction device is operable in response to a second energy form different than the first form to vary the restricted stoma. An energy transfer device is implanted in the patient for transferring energy of the first form transmitted by the energy transmission device into energy of the second form. The energy transfer device includes at least one element having a positive region and a negative region, and 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 produces the energy of the second form. |
