A driver tool drives multiple fasteners (52) simultaneously through the outer ring of a heart valve component into the surrounding tissue annulus of a heart. The driver tool includes two stacked satellite gear layers (108, 110) that drive flexible shafts (104, 106) that simultaneously drive the fasteners (52) into tissue surrounding the heart valve component. The flexible shafts (104, 106) from the second drive gear layer (110) can pass through gaps between satellite gears (100) in the first drive gear layer (108).
L'invention concerne un outil entraîneur qui commande plusieurs attaches (52) simultanément par le biais d'un anneau externe d'un composant de valvule cardiaque dans l'annulus tissulaire environnant d'un coeur. L'outil entraîneur comprend deux couches de pignons satellites empilées (108, 110) qui entraînent des tiges flexibles (104, 106) qui commandent simultanément les attaches (52) dans les tissus environnants le composant de valvule cardiaque. Les tiges flexibles (104, 106) de la seconde couche de pignons menants (110) peuvent passer à travers des trous entre des pignons satellites (100) dans la première couche des pignons menants (108).
