Claim Text:
1. A paddle lead assembly for providing electrical stimulation of patient tissue, the paddle lead assembly comprising: a paddle body; a plurality of electrodes disposed along the paddle body and arranged into four columns of electrodes that each comprise at least two electrodes and that each extend along the paddle body; four lead bodies coupled to the paddle body; a plurality of terminals arranged into four terminal arrays with each terminal array comprising at least two terminals and disposed along a different one of the four lead bodies; an extension element coupled between the paddle body and the four lead bodies, the extension element comprising at least one divider that divides an interior of the extension element into four co-axial regions separated by the at least one divider; and a plurality of conductive wires electrically coupling the electrodes to the terminals, wherein each terminal array is electrically coupled to a different one of the four columns of electrodes, wherein the plurality of conductive wires are divided into four distinct wire groupings with each of the four distinct wire groupings having different conductive wires of the plurality of conductive wires from the remaining distinct wire groupings, wherein each of the four distinct wire groupings extends along a different one of the four separate co-axial regions.
