Abstract[English]
Systems, devices, and related implantation methods of the wireless-powered electrical stimulator are generally provided. A typical system includes a wearable transmitter for wireless power transfer and an implanted electrical stimulator. Specifically, the electrical stimulator comprises a power management module, a pulse generator, and one or more pairs of electrodes. In some embodiments, the electrical stimulator may include a microcontroller and some sensors detecting related physiological signals of target muscle groups for closed-loop electrical therapy. Moreover, minimally invasive implantation procedures are also disclosed for electrical stimulation therapy through a natural orifice, like the gastrointestinal tract. In some embodiments, electrical stimulation is applied continuously to restore the normal functions of target muscle groups.[French]
La présente invention concerne généralement des systèmes, des dispositifs et des procédés d’implantation associés du stimulateur électrique alimenté sans fil. Un système typique comprend un émetteur portable pour le transfert d’énergie sans fil et un stimulateur électrique implanté. Spécifiquement, le stimulateur électrique comprend un module de gestion d’énergie, un générateur d’impulsions et une ou plusieurs paires d’électrodes. Dans certains modes de réalisation, le stimulateur électrique peut comprendre un microcontrôleur et certains capteurs détectant des signaux physiologiques associés de groupes de muscles cibles pour une thérapie électrique en boucle fermée. De plus, l’invention concerne en outre des procédures d’implantation mini-invasives pour une thérapie de stimulation électrique par l’intermédiaire d’un orifice naturel, tel que le tractus gastro-intestinal. Dans certains modes de réalisation, une stimulation électrique est appliquée en continu pour restaurer les fonctions normales de groupes de muscles cibles.
