Title (EN) CARDIAC VALVE ANNULUS REDUCTION SYSTEM
(FR) SYSTEME DE REDUCTION DE L'ANNULUS DES VALVULES CARDIAQUES
Abstract:
(EN) A catheter-based, annulus reduction device and system (100, 200) for cardiac valve repair and method of using the same. The system is usable for treating mitral valve regurgitation and comprises a catheter (252), a reduction ring (220) carried within the catheter, the reduction ring including a plurality of exit ports (224) formed in a side wall of the reduction ring and filament (214) received in the reduction ring. The filament includes a plurality of radially extendible barbs (212) corresponding to the sidewall openings. The reduction ring carrying the filament is deployed adjacent a mitral valve annulus and the filament is translated relative to the reduction ring to deploy the barbs through the exit ports and into the annulus and to further translate the reduction ring with deployed barbs to reshape the annulus.
(FR) La présente invention concerne, d'une part un dispositif et un système de réduction de l'annulus, à base de cathéter, pour réparer les valvules cardiaques, et d'autre part un procédé d'utilisation correspondant. Ce système, qui est disponible pour traiter la régurgitation de la valvule mitrale, comprend un cathéter, un anneau réducteur porté à l'intérieur du cathéter et comprenant une pluralité d'orifices de sortie dans l'une de ses parois latérales, un filament étant reçu dans l'anneau réducteur. Le filament comporte une pluralité de barbules à déploiement radial correspondant aux orifices de la paroi latérale. On déploie contre l'annulus de la valvule mitrale l'anneau réducteur portant le filament, puis le filament subit une translation par rapport à l'anneau réducteur, ce qui fait que, d'une part les barbules se déploient au travers des orifices de sortie, pénétrant dans l'annulus, et d'autre part on continue à faire glisser l'anneau réducteur aux barbules déployées de façon à modifier la forme de l'annulus.
