Abrégé
(EN)
The invention relates to an implantable stomach prosthesis (30) for surgically replacing or augmenting all or part of the antrum and/or pylorus of a stomach (200). The prosthesis (30) controls the passage of food from the stomach to the small intestine. The prosthesis (30) may be configured to churn ingested material and release it from the stomach through a prosthetic pyloric valve (38). At least one expandable member (36) is arranged to be expanded to control the passage of food and/or to mimic the churning action of a patient's stomach. The prosthesis (30) includes an outer support structure (31), a flexible inner member (32) forming a conduit for the movement of material, and at least one expandable member (36) located between the outer support structure (31) and inner member (32). An implantable pump system (40) is provided for inflating and deflating the expandable member(s) (36).

L'invention se rapporte à une prothèse d'estomac implantable permettant de remplacer chirurgicalement ou d'augmenter toute ou partie de l'antre et/ou du pylore d'un estomac. Ladite prothèse régule le passage de la nourriture de l'estomac vers l'intestin grêle. Cette prothèse peut être conçue pour agiter la matière ingérée et pour l'évacuer de l'estomac à travers une valvule pylorique. Au moins un élément dilatable est disposé de manière à être dilaté pour réguler le passage des aliments et/ou pour imiter l'effet d'agitation d'un estomac de patient. Cette prothèse comprend une structure de support externe, un élément interne souple formant un conduit pour le déplacement de matière, et au moins un élément dilatable situé entre la structure de support externe et l'élément interne. L'invention concerne un système de pompe implantable permettant de gonfler et de dégonfler ledit élément ou lesdits éléments dilatables.
