Disclosed are methods and devices for determining valve leaflet orientation. A catheter (778) is provided with a conformable, radiopaque target (780). The target is deployed within a valve, such as the mitral valve. The conformable target conforms to the coaptation axis (788) in response to closing of the valve leaflets (776). That coaptation axis may then be visualized, and utilized to determine information about valve operation, or to assist in placement of devices in the vicinity of the valve.
La présente invention concerne des procédés et des dispositifs permettant déterminer l'orientation de feuillets de valvule. Un cathéter est pourvu d'une cible radio-opaque souple. La cible est déployée à l'intérieur de la valvule, telle que la valvule mitrale. La cible souple s'adapte à l'axe de coaptation en réaction à la fermeture des feuillets de valvule. L'axe de coaptation peut ensuite être visualisé, et utilisé pour déterminer des informations concernant le fonctionnement de la valvule, ou pour faciliter la pose de dispositifs à proximité de la valvule.
