Abstract
An implantable electrode paddle for use in a neurostimulation system may include a dorsally-projecting lead that allows all of the edges of the electrode paddle to be situated near a vertebral body for stimulation of neural structures. Embodiments may include one or more flanges for cooperating with a vertebral body and thereby stabilizing the electrode paddle. Embodiments of the present invention may also include features to allow an electrode paddle to be divided during surgery. Embodiments of the present invention may also include an electrode paddle having a plurality of paddle sections, wherein at least one of the paddle sections comprises a plurality of asymmetrically configured contacts. Embodiments of the invention include a method of assembling a neurostimulation system and a method of implanting an implantable system in a body, wherein the implantable system includes an electrode paddle that may be divided into a plurality of paddle sections.
