Beschreibung
Zusammenfassung:	An implantable medical device is disclosed that includes a valve seat and a valve member movable with respect to the valve seat. An adjustment circuit assembly includes a resistive element that is coupled to the valve member and operable to position the valve member relative to the valve seat so as to alter the pressure setting in response to a current applied to the resistive element. L'invention porte sur un dispositif médical implantable qui comprend un siège et un élément de valve pouvant se déplacer par rapport au siège. Un ensemble circuit d'ajustement comprend un élément résistant qui est couplé à l'élément de valve et qui est actionnable pour positionner l'élément de valve par rapport au siège de façon à modifier le réglage de pression en réponse à un courant appliqué à l'élément résistant.
