Beschreibung
Zusammenfassung:	Artificial contractile structure (1) for a medical device, said artificial contractile structure (3) comprising: - an elongated member (3) adapted to contact a hollow body organ; - a closure (9) adapted to form the artificial contractile structure (1) into a closed loop around said hollow body organ; - a tension system (11) arranged to be connected to a control unit (28), said tension system (1) being adapted to modify an internal diameter of said closed loop in response to a force applied by said control unit (28). According to the invention, said elongated member (3) comprises a resilient core (5) and a biocompatible outer sheath (7). Said tension system (11) furthermore comprises a first tensile element (13) attached to a first point (3c) of said elongated member, and a second tensile element (15) attached to a second point (3d) of said elongated member, each of said tensile elements (15, 17) passing through an adaptor (17) situated between said first point (3c) and said second point (3d). L'invention concerne une structure contractile artificielle (1) pour un dispositif médical, ladite structure contractile artificielle (3) comprenant : - un élément allongé (3) conçu pour entrer en contact avec un organe corporel creux ; - une fermeture (9) conçue pour former la structure contractile artificielle (1) en une boucle fermée autour dudit organe corporel creux ; - un système de tension (11) agencé pour être relié à une unité de contrôle (28), ledit système de tension (1) étant apte à modifier un diamètre interne de ladite boucle fermée en réponse à une force appliquée par ladite unité de contrôle (28). Selon l'invention, ledit élément allongé (3) comprend un noyau élastique (5) et une gaine externe biocompatible (7). Ledit système de tension (11) comprend en outre un premier élément de traction (13) fixé à un premier point (3c) dudit élément allongé, et un second élément de traction (15) fixé à un second point (3d) dudit organe allongé, chacun desdits éléments de traction (15, 17) passant par un adaptateur (17) situé entre ledit premier point (3c) et ledit second point (3d).
