AN IMPLANTABLE ELECTROCORTICOGRAM BRAIN-COMPUTER INTERFACE SYSTEM FOR RESTORING EXTREMITY MOVEMENT
(FR)
SYSTÈME D'INTERFACE CERVEAU-ORDINATEUR PAR ÉLECTROCORTICOGRAMME IMPLANTABLE POUR RESTAURER LE MOUVEMENT DES EXTRÉMITÉS
Abstract:
(EN)
A fully-implantable brain-computer interface cyber-physical system capable of acquiring and analyzing electrocorticogram ("ECoG") signals, recorded directly from the subdural space of the brain, to enable direct brain control of a prosthetic (e.g., a robotic gait exoskeleton or a functional electrical stimulation ("FES") system) is disclosed. The present system comprises a plurality of electrodes, for acquiring the ECoG signals, and a digital signal processor ("DSP") for deriving a plurality of real-time commands from the ECoG signals. These real-time commands may then be wireless!y transmitted to the prosthetic for execution. Further, to avoid wireless data transmission of the ECoG signals from the plurality of electrodes to the DSP, which would expose the brain, skull, and scalp tissue to potentially harmful radio frequencies, a subcutaneous tunneling cable operatively couples the plurality of electrodes and the DSP.
(FR)
La présente invention concerne un système cyber-physique d'interface cerveau-ordinateur entièrement implantable apte à acquérir et à analyser des signaux d'électrocorticogramme (" ECoG "), enregistrés directement à partir de l'espace sous-dural du cerveau, pour permettre une commande directe par le cerveau d'une prothèse (par exemple, un exosquelette de marche robotique ou un système de stimulation électrique fonctionnelle (" FES ")). Le présent système comprend une pluralité d'électrodes, permettant d'acquérir les signaux d'ECoG, et un processeur de signal numérique (" DSP ") permettant de dériver une pluralité de commandes en temps réel à partir des signaux d'ECoG. Ces commandes en temps réel peuvent ensuite être transmises sans fil à la prothèse pour l'exécution. En outre, afin d'éviter la transmission de données sans fil des signaux d'ECoG de la pluralité d'électrodes au DSP, ce qui exposerait le cerveau, le crâne et le tissu du cuir chevelu à des fréquences radio potentiellement dangereuses, un câble de tunnellisation sous-cutané couple de manière fonctionnelle la pluralité d'électrodes et le DSP.
