Abstract: An electrostimulation device (e.g., 100) consists of a single paddle (e.g., 102) and at least one lead (e.g., 110) for connecting the electrostimulation device to a pulse generator. The paddle has at least one electrode (e.g., 106) for providing electrical stimulation. The electrode(s) is provided in an area (A) of the paddle and a ratio of the width of the area to the length of the area is greater than 0.5. The present invention also relates to a paddle (e.g., 102) implantable in a vertebra.
