Abstract

L'invention concerne un système de prothèse de valvule (68) qui comprend une valvule aortique prothétique (120) et une unité non implantable (70, 100). La valvule aortique prothétique (120) comprend une pluralité de feuillets prothétiques (32); un cadre (30); une cathode (54) et une anode (57); et une bobine de valvule prothétique (36), qui est en communication électrique non sans fil avec la cathode (54) et l'anode (57). L'unité non implantable (70, 100) comprend une bobine de transmission d'énergie (74, 102); et un circuit de commande non implantable (70, 104), qui est conçu pour amener la cathode (54) et l'anode (57) à appliquer un signal de stimulation et pour : régler des paramètres du signal de stimulation, par transfert sans fil d'énergie provenant de la bobine de transmission d'énergie (74, 102) à la bobine de valvule prothétique (36) par couplage inductif; commencer l'application de chaque impulsion du signal de stimulation en commençant par le transfert sans fil de l'énergie de la bobine de transmission d'énergie à la bobine de valvule prothétique; et conclure l'application de chaque impulsion du signal de stimulation par l'arrêt du transfert sans fil de l'énergie de la bobine de transmission d'énergie à la bobine de valvule prothétique. L'invention décrit également d'autres modes de réalisation.
