Abstract:
A food intake restriction apparatus for an obese patient, comprising:an energy transmission device for wireless transmission of energy of a first form from outside the patient's body; an operable restriction device adapted to be implanted in the patient to engage the stomach or the esophagus to form an upper small pouch of the stomach and a restricted stoma opening in the stomach or esophagus, said restriction device operable in response to a second energy form different than the first form energy to vary the restricted stoma; 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.
