A method and apparatus for reducing mitral regurgitation. The apparatus (90) is inserted into the coronary sinus (50) of a patient in the vicinity of the posterior leatlet of the mitral valve, the apparatus being adapted to straighten the natural cuwature of at least a portion of the coronary sinus in the vicinity of the posterior leaflet of the mitral valve, whereby to move the posterior annulus anteriorly and thereby improve leaflet coaptation and reduce mitral regurgitation. The apparatus is also configured to work in conjunction with an electrical lead (600) for an implantable bi-ventricular pacing device, an electrical lead for an implantable cardio defibrillator, etc.

L'invention concerne une méthode et un appareil destinés à réduire la régurgitation mitrale. Cet appareil est inséré dans le sinus coronaire d'un patient au voisinage du feuillet postérieur de la valvule mitrale, et permet de redresser l'incurvation naturelle d'une partie au moins du sinus coronaire au voisinage du feuillet postérieur de la valvule mitrale, ce qui permet de déplacer l'anneau postérieur par voie antérieure et, donc, d'améliorer la coaptation et de réduire la régurgitation mitrale. Ledit appareil est également conçu pour fonctionner conjointement avec un conducteur électrique pour un dispositif de stimulation biventriculaire implantable, un conducteur électrique pour un défibrillateur cardiaque, etc.
