Claim:
1. A neurostimulation paddle lead, comprising: an elongated lead body having a proximal end, a distal end, and a longitudinal axis; a plurality of terminals carried by the proximal end of the lead body; a paddle-shaped membrane disposed on the distal end of the lead body; and a plurality of electrodes arranged on an exterior surface of the paddle-shaped membrane in electrical communication with the respective terminals, the plurality of electrodes comprising at least four columns of electrodes, each column extending along the paddle-shaped membrane in a longitudinal direction, the at least four electrode columns having at least two inner electrode columns and two outer electrode columns transversely flanking the at least two inner electrode columns, wherein one of the at least two inner electrode columns is offset from one of the two outer electrode columns in the longitudinal direction, such that a plurality of immediately adjacent electrodes in the one outer electrode column longitudinally span only one electrode in the one inner electrode column.
