Apparatus and method for adjustably restricting a selected body lumen such as an anal canal of a patient to passively treat fecal incontinence. The apparatus in various examples comprises a plurality of expandable elements. Each of the elements is comprised of a membrane of biocompatible material enclosing a volume. The elements expand upon introduction of fluid into the elements and contract upon withdrawal of fluid from the elements. The expandable elements are adjustable in size by adjusting an amount of fluid in the elements. Fluid communication to the expandable elements is provided by a plurality of flexible conduits of biocompatible material coupled to both the expandable elements and a fill port block comprising a plurality of fill ports.

La présente invention se rapporte à un appareil et à un procédé permettant de restreindre de manière réglable le diamètre d'une lumière corporelle sélectionnée telle que le canal anal d'un patient, afin de permettre un traitement passif de l'incontinence fécale. L'appareil selon l'invention comprend, dans diverses variantes, une pluralité d'éléments dilatables. Chacun desdits éléments est constitué d'une membrane de matière biocompatible entourant un volume. Les éléments se dilatent lors de l'introduction d'un fluide, et se contractent lors du retrait dudit fluide. L'on peut régler la taille des éléments dilatables en faisant varier le volume de fluide contenu dans ces derniers. La communication fluidique vers lesdits éléments dilatables est assurée par une pluralité de conduits souples faits d'une matière biocompatibles, qui sont couplés à la fois aux éléments dilatables et à une unité orifice de remplissage comprenant une pluralité d'orifices de remplissage.
