Title
(EN) PROCESSES FOR VAD CONTROLLER EXCHANGE AND SOFTWARE UPGRADE WITH UNINTERRUPTED CIRCULATORY SUPPORT

Abstract
(EN) A method of operating an implantable blood pump including connecting the implantable blood pump to a primary controller, the primary controller being configured to operate the implantable blood pump, and a secondary controller. The secondary controller synchronizes its own motor drive signals to a frequency and phase of the primary controller's motor drive signals, without actively contributing power to the implantable blood pump. An imminent or actual disconnection event is detected in which the primary controller is disconnected from the implantable blood pump. Uninterrupted operation of the implantable blood pump is continued with the secondary controller.
(FR) L'invention concerne une méthode d'utilisation d'une pompe à sang implantable consistant à relier la pompe à sang implantable à un dispositif de commande primaire, le dispositif de commande primaire étant conçu pour faire fonctionner la pompe à sang implantable, et un dispositif de commande secondaire. Le dispositif de commande secondaire synchronise ses propres signaux d'entraînement de moteur avec une fréquence et une phase des signaux d'entraînement de moteur du dispositif de commande primaire, sans apporter activement de l'énergie à la pompe à sang implantable. Un événement de déconnexion imminent ou réel est détecté, au cours duquel le dispositif de commande primaire est déconnecté de la pompe à sang implantable. Le fonctionnement ininterrompu de la pompe à sang implantable est poursuivi avec le dispositif de commande secondaire.
