Title (EN) INTERMEDIATE COUPLER TO FACILITATE CHARGING IN AN IMPLANTABLE MEDICAL DEVICE SYSTEM
(FR) COUPLEUR INTERMÉDIAIRE DESTINÉ À FACILITER LA CHARGE DANS UN SYSTÈME DE DISPOSITIF MÉDICAL IMPLANTABLE
Abstract:
(EN) An intermediate coupler is used to improve inductive coupling between an external charger and an implantable medical device having a battery requiring charging. The intermediate coupler comprises a coil (inductor) coupled to a capacitor, whose values are chosen to resonate at the frequency of the magnetic field emitted by the external charger. The intermediate coupler preferably contains no power source such as a battery, and can operate passively. When the intermediate coupler receives the magnetic field from the external charger, a current is induced in its coil, and the intermediate coupler generates its own magnetic field which is captured by the implantable medical device and used to charge its battery.
(FR) L'invention concerne un coupleur intermédiaire destiné à améliorer un couplage inductif entre un chargeur externe et un dispositif médical implantable pourvu d'une batterie à charger. Ce coupleur intermédiaire comprend une bobine (bobine d'induction) couplée à un condensateur, dont les valeurs sont sélectionnées pour résonner à la fréquence du champ magnétique émis par le chargeur externe. Le coupleur intermédiaire ne comprend de préférence pas de source d'alimentation telle qu'une batterie et peut fonctionner passivement. Lorsque le coupleur intermédiaire reçoit le champ magnétique du chargeur externe, un courant est induit dans sa bobine et le coupleur intermédiaire génère son propre champ magnétique qui est capturé par le dispositif médical implantable et utilisé pour charger sa batterie.
