An apparatus for controlling flow of intestinal contents in a patient suffering from, intestinal dysfunction, such as anal incontinence, reduced peristaltic function of the intestines and constipation, comprises an implantable constriction device for gently constricting (i.e. without substantially hampering the blood circulation in the tissue wall of the intestines) at least one portion of the tissue wall of the intestines to influence the flow of intestinal contents in the intestines, and a stimulation device for stimulating the wall portion of the tissue wall. A control device controls the stimulation device to stimulate the wall portion, as the constriction device constricts the wall portion, to cause contraction of the wall portion constricted by the constriction device to further influence the flow of intestinal contents in the intestines. The apparatus can be used for restricting or stopping the flow of intestinal contents in the intestines, or for actively moving the intestinal contents in the intestines, with a low risk of injuring the intestines.

La présente invention concerne un appareil destiné à réguler le flux de contenus intestinaux chez un patient souffrant d'un trouble intestinal tel que l'incontinence anale, la fonction péristaltique réduite des intestins et la constipation, l'appareil comprenant un dispositif de constriction implantable destiné à réaliser une légère constriction (c.-à-d. sensiblement sans entraver la circulation sanguine dans la paroi tissulaire des intestins) d'au moins une partie de la paroi tissulaire des intestins pour agir sur le flux de contenus intestinaux dans les intestins, et un dispositif de stimulation destiné à stimuler la partie de la paroi tissulaire. Un dispositif de commande commande le dispositif de stimulation pour qu'il stimule la partie de paroi, lorsque le dispositif de constriction réalise la constriction sur la partie de paroi, pour provoquer la contraction de la partie de paroi qui subit la constriction par le dispositif de constriction, pour agir plus amplement sur le flux de contenus intestinaux dans les intestins. L'appareil peut être utilisé pour restreindre ou stopper le flux de contenus intestinaux dans les intestins ou pour assurer le déplacement actif des contenus intestinaux dans les intestins, avec un risque faible de lésion des intestins.
