A device for controlling the expansion of a hollow internal organ, comprising an inflatable balloon, which is inserted in an uninflated state into the desired position close to the organ using minimally invasive procedures. After insertion, the balloon is inflated to its required size and shape. The invention is useful for restricting the expansion of the stomach during meals, thus inducing a feeling of satiety and preventing over-eating. Inflation may be performed through a catheter connected to a readily accessible inflation port. In the case of the gastric embodiment, the balloon may be positioned pro- peritoneally, such that the procedure is surgically simple. One or more sensors located close to the organ to be controlled, may monitor a physiological effect relating to the organ, and the output of the sensor used to control the level of inflation of the balloon in order to correct the condition being monitored.

Dispositif permettant de contrôler l'expansion d'un organe interne creux, qui comprend un ballon gonflable, inséré à l'état non gonflé en position souhaitée près de l'organe, par des procédures à effraction minimale. Après l'insertion, on gonfle le ballon à la taille et à la forme requises. Il s'agit d'un produit utile pour restreindre l'expansion de l'estomac en cours de repas, ce qui induit une sensation de satiété et empêche la sur-alimentation. Le gonflement peut intervenir via un cathéter relié à un orifice de gonflement facilement accessible. Pour une application gastrique, le ballon peut être placé en position propéritonéale, ce qui rend la procédure simple du point de vue chirurgical. Un ou plusieurs capteurs placés près de l'organe à contrôler peuvent assurer le contrôle d'un effet physiologique relatif à l'organe, et l'information fournie par capteur permet de contrôler le niveau de gonflage du ballon en vue de corriger l'état contrôlé.
