A device for treatment of mitral annulus dilatation comprises an elongate body having two states. In a first of these states the elongate body is insertable into the coronary sinus and has a shape adapting to the shape of coronary sinus. When positioned in the coronary sinus, the elongate body is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced. The elongate body comprises a distal stent section, a proximal stent section and control wires for reducing the distance between the distal and proximal stent sections.

Cette invention se rapporte à un dispositif destiné au traitement d'une distension de l'anneau mitral et comprenant un corps allongé présentant deux états. Dans son premier état, le corps allongé peut être introduit dans le sinus coronaire et présente une forme s'adaptant à celle dudit sinus coronaire. Lorsque ledit corps allongé est en position dans le sinus coronaire, il peut passer à son second état, présentant un rayon de courbure réduit, entraînant ainsi une réduction du rayon de courbure du sinus coronaire et du rayon de courbure ainsi que de la circonférence de l'anneau mitral. Ce corps allongé comporte une partie tuteur distale, une partie tuteur proximale et des fils de commande permettant de réduire la distance entre la partie distale et la partie proximale du tuteur.
