Abstract
An apparatus (100) is described that comprises a generator unit (1) of generating electrical stimulation signals and a spinal cord stimulation unit (2) encompassing a plurality of stimulation contact surfaces (11-14) to which the generator unit (1) feeds the stimulation signals. At least two of the stimulation contact surfaces (11-14) are arranged in a staggered manner transverse to the direction in which the spinal cord extends.
