Abstract

DISPOSITIF DE STIMULATION NEURALE INTRINS È QUEMENT É QUILIBR É E L’invention concerne un aiguilleur de courant comportant : un bus d’alimentation positive (18) et un bus d’alimentation négative (20) ;un amplificateur de courant à sortie flottante (22) configuré pour faire circuler, en sortie, un courant intermédiaire dépendant d’un courant de consigne circulant appliqué en entrée ;au moins un dipôle de référence anodique (24) connecté entre le bus d’alimentation positive (18) et l’amplificateur de courant à sortie flottante (22) ;au moins un dipôle de référence cathodique (26) connecté entre l’amplificateur de courant à sortie flottante (22) et le bus d’alimentation négative (20) ; etau moins deux ponts de stimulation (28), chaque pont de stimulation (28) comportant une source de courant anodique (34) et une source de courant cathodique (36) chacune configurée pour copier le courant intermédiaire.
