Method and apparatus for treatment of morbid obesity by placement of a series of flow reduction elements in the small intestine to induce satiety are disclosed. The flow reduction elements restrict the movement of partially digested food and reduce the flow rate through the small intestine which causes the emptying of the stomach and the duodenum to occur slower. The flow reduction elements are attached to an elongated tube and are constructed from various shapes and configurations. The flow reduction elements may be inflated with fluid or may be constructed from self-expandable materials. The device is anchored in the antrum of the stomach with an anchoring member. The transoral gastric device can be inserted with a delivery catheter through the working lumen of an endoscope or alongside an endoscope and may be removed with the aid of an endoscope if desired.

L'invention concerne un procédé et un appareil destinés au traitement de l'obésité morbide et consistant à placer une série d'éléments de réduction de flux dans l'intestin grêle, de manière à induire la satiété. Les éléments de réduction de flux restreignent le déplacement d'aliments partiellement digérés et réduisent le débit dans l'intestin grêle, l'estomac et le duodénum se vidant ainsi plus lentement. Les éléments de réduction de flux sont fixés sur un tube allongé et présentent diverses formes et conceptions. Les éléments de réduction de flux peuvent être gonflés au moyen de fluide ou peuvent être construits dans des matériaux à auto-expansion. Le dispositif est fixé dans l'antre de l'estomac au moyen d'un élément de fixation. Le dispositif gastrique transoral peut être introduit au moyen d'un cathéter d'administration par le biais d'une lumière de travail d'un endoscope ou conjointement avec un endoscope et être retiré au moyen d'un endoscope en fonction des besoins.
