Abstract
An implantable neurostimulation lead kit adapted for tripolar electric simulation and/or field steering using percutaneously implantable electric stimulation leads. The kit includes three electric stimulation leads that are adapted to provide an electrode array defining, for example, a plurality of electrode sets that may be used to provide tripolar stimulation and/or electric field steering. A method of electrically stimulating the spinal cord is also described.
