Abstract

La présente invention concerne un système de mise en place destiné à mettre en place une prothèse valvulaire à l'état comprimé sur un arbre interne d'un cathéter. Le système de mise en place comprend un embout s'étendant distalement depuis l'arbre interne. L'embout présente une section proximale et une section distale opposée s'étendant jusqu'à une extrémité de l'embout. La section proximale est configurée pour soutenir une extrémité de la valve prothétique pendant le chargement et la mise en place de la prothèse valvulaire cardiaque et comprend une première partie, une deuxième partie et une troisième partie. La première partie est adjacente à la section distale. La deuxième partie est située entre la première partie et la troisième partie. La troisième partie est adjacente à une extrémité proximale de l'embout. Le diamètre extérieur de la première partie est supérieur au diamètre extérieur de l'arbre interne, au diamètre extérieur de la deuxième partie et au diamètre extérieur de la troisième partie.
