Patent ID: 7987000

Claim:
A neurostimulation paddle lead, comprising: at least one 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 at least one lead body; a paddle-shaped membrane disposed on the distal end of the at least one 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 electrodes extending along the paddle-shaped membrane in a direction transverse to the longitudinal axis, the at least four electrodes having first and second inner electrodes immediately adjacent to each other, a first outer electrode immediately adjacent to the first inner electrode, and a second outer electrode immediately adjacent to the second inner electrode, wherein a first transverse spacing between the first and second inner electrodes is less than each of a second transverse spacing between the first inner electrode and the first outer electrode, and a third transverse spacing between the second inner electrode and the second outer electrode.
