Gastrointestinal prosthesis for restraining the rate of the gastric digestion consists of a compressible proximal member connected by a string to a distal member, to be introduced into the intestine. The proximal member has an internal space, which is opened to the gastric lumen and may include passageways for the gastric content as well as open grooves or niches disposed on its external wall. The volume of a proximal member compressed by the gastric wall cannot get smaller than a lower threshold. Anchoring the gastrointestinal prosthesis at its desired location is accomplished by means of the proximal member the geometrical shape of which conforms the geometrical shape of a portion of the gastric lumen; as well as by means of the geometrical shape of the distal member which conforms the geometrical shape of a segment of the duodenum and/or a segment of the intestine.
L'invention concerne une prothèse gastro-intestinale pour limiter la vitesse de la digestion gastrique consistant en un élément proximal compressible relié par un cordon à un élément distal, devant être introduit dans l'intestin. L'élément proximal a un espace interne, qui est ouvert à la lumière gastrique et peut comprendre des passages pour le contenu gastrique ainsi que des rainures ouvertes ou des niches disposées sur sa paroi externe. Le volume d'un élément proximal comprimé par la paroi gastrique ne peut pas devenir plus petit qu'un seuil inférieur. L'ancrage de la prothèse gastro-intestinale à l'emplacement désiré est accompli au moyen de l'élément proximal dont la forme géométrique se conforme à la forme géométrique d'une partie de la lumière gastrique, ainsi qu'au moyen de la forme géométrique de l'élément distal qui se conforme à la forme géométrique d'un segment du duodénum et/ou d'un segment de l'intestin.
