A food intake restriction apparatus comprises a restriction device (56) implantable in an obese patient, for engaging the stomach or esophagus to form an upper pouch of the stomach and a restricted stoma opening in the stomach or esophagus. The restriction device is operable by an implantable operation device (60) to change the size of the stoma opening. A control device (62 and 64) is provided for controlling a source of energy, which may or may not be implanted, from outside the patient's body, to release energy for use in connection with the operation of the restriction device, i.e. to power the operation device.

Cette invention se rapporte à un appareil restreignant l'absorption de nourriture, qui comprend un dispositif de restriction (56) implantable dans l'organisme d'un patient obèse, pour amener l'estomac ou l'oesophage à former une poche supérieure de l'estomac et une ouverture d'ostomie restreinte dans l'estomac ou l'oesophage. Le dispositif de restriction peut être activé par un dispositif d'actionnement implantable (60), permettant de faire varier la taille de l'ouverture d'ostomie. Un dispositif de commande (62 et 64) est prévu pour commander une source d'énergie, pouvant être implantée ou non, depuis l'extérieur du corps du patient, en vue de libérer de l'énergie servant à l'actionnement du dispositif de restriction, c'est-à-dire pour activer le dispositif d'actionnement.
