Abstract
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.
