A device (ES) for distributing power between n cathodes (Ki) of at least one multipolar stimulating electrode (EM) comprises at least one anode (A), wherein n is equal to or greater than two. Said device (ES) comprises a reconfigurable current mirror (MC) which is provided with n outputs (K'i) connectable to said n cathodes (Ki), respectively and supplies to the n (K'i) outputs n complementary fractions of a control current having respective selected values which are substantially constant at the control current amplitude variation in order to carry out a substentially constant spatial location of stimulation.
Un dispositif (ES) est dédié à la répartition de courant entre n cathodes (Ki) d'au moins une électrode multipolaire de stimulation (EM) comportant en outre au moins une anode (A), n~étant supérieur ou égal à deux. Ce dispositif (ES) comporte un miroir de courant reconfigurable (MC) comportant n sorties (K'i) propres à être couplées respectivement auxdites n cathodes (Ki) et chargé de délivrer sur les n sorties (K'i) n fractions complémentaires d'un courant de commande, de valeurs respectives choisies et sensiblement constantes en présence d'une variation d'amplitude du courant de commande, afin de permettre la localisation spatiale sensiblement constante de la stimulation.
