Abstract
A paddle lead assembly for providing electrical stimulation of patient tissue includes a paddle body having a longitudinal axis and a lateral axis transverse to the longitudinal axis. The paddle body includes a plurality of electrodes disposed into at least four columns extending parallel with the longitudinal axis. The at least four columns include two lateral columns and at least two medial columns disposed therebetween. The electrodes of the at least two medial columns are arranged into rows aligned along the transverse axis. The electrodes of the two lateral columns are each longitudinally offset from the rows of electrodes of the at least two medial columns. An array of terminals are disposed on each of at least one lead body coupled to the paddle body. A plurality of conductive wires couple each of the electrodes to at least one terminal of the terminal arrays.
