The invention relates to device (1; 1') for closing a natural or artificial anus, comprising an inflatable balloon (2) with an approximately toroidal structure made from a flat tube section, which is turned inside out and whose both ends (7, 8) extend coaxially into one another and are each joined to a sleeve (9). The outer layer (5) of the tube section that is turned inside out has a radially enlarged, patient-proximal area (3) for inserting into the rectum and has a patient-distal area (11, 7, 8), which is tapered thereto and which remains, at least in areas, outside of the rectum during use. The tube sections have, in the transanal area (11, 7, 8), a material hardness H1 of greater than 60 according to Shore hardness test A. According to the invention, a stiffening sleeve (14) is placed inside the interrectal area (3) of the inner layer (5) in such a manner that this sleeve is completely separated from the hollow space (10) inside the balloon (2) by its inner penetrable layer (5).

L'invention concerne un dispositif (1; 1') permettant de fermer un anus naturel ou artificiel, qui comprend un ballonnet (2) gonflable de structure approximativement torique, formé d'une section de flexible tubulaire plate, retournée en soi, dont les deux extrémités (7, 8) s'étendent l'une dans l'autre, de manière approximativement coaxiale et sont reliées (chacune) à un manchon (9). La couche extérieure (5) de la section de flexible tubulaire retournée présente une zone (3) évasée dans le sens radial, à situation proximale du patient, destinée à être introduite dans le rectum et une zone (11, 7, 8) comparativement réduite, à situation distale du patient, qui demeure au moins en partie en dehors du rectum, en cours d'utilisation. Les sections de flexible tubulaire présentent dans la zone transanale (11, 7, 8, 9) une dureté de matériau H1 pouvant être déterminée par vérification de dureté Shore A, qui est supérieure à 60. Selon l'invention, un manchon de renfort (14) est inséré dans la zone intrarectale (3) de la couche intérieure (5), de sorte que ledit manchon de renfort se trouve entièrement séparé de la cavité (10) suitée à l'intérieur du ballonnet (2), par sa couche intérieure (5) pouvant être traversée.
