Abstract
The present invention relates to an epidural stimulation lead having at least one electrode that substantially encircles another electrode. Operatively, the encircling electrode can be set as an, anode and the encircled electrode can be set as a cathode to generate an electrical field therebetween. The encircling electrode functions in this capacity as an anode guard, which among other things, concentrates the electrical field about the designated cathode and limits the lateral range of a generated electrical field.
