Title
(EN) IMPLANTABLE MEDICAL DEVICE WITH MULTI-BAND LOOP ANTENNA
(FR) DISPOSITIF MÉDICAL IMPLANTABLE À ANTENNE CADRE MULTIBANDE
Abstract
(EN)
Embodiments presented herein are generally directed to implantable medical devices that are configured for both near-field communication and far-field communication via the same implantable loop antenna. More specifically, the implantable medical devices include implant electronics that are independently coupled to the loop antenna via a transformer and an isolation coupler. The transformer is configured to provide near-field signals received at the loop antenna to the implant electronics, while the isolation coupler is configured to provide far-field signals received at the loop antenna to the implant electronics.
(FR)
Selon certains modes de réalisation, la présente invention concerne de manière générale des dispositifs médicaux implantables qui sont configurés à la fois pour une communication en champ proche et une communication en champ lointain par l'intermédiaire de la même antenne cadre implantable. Plus spécifiquement, les dispositifs médicaux implantables comprennent des composants électroniques d'implant qui sont couplés de manière indépendante à l'antenne cadre par l'intermédiaire d'un transformateur et d'un coupleur d'isolation. Le transformateur est configuré pour transmettre des signaux de champ proche reçus par l'antenne cadre aux composants électroniques d'implant, tandis que le coupleur d'isolation est configuré pour transmettre des signaux de champ lointain, reçus par l'antenne cadre, aux composants électroniques d'implant.
