Abstract
A system for stimulation includes an implantable pulse generator, a lead, and conductors. The lead includes an array body disposed at a distal end of the lead and electrodes concentrically arranged on the array body. A center electrode may also be disposed on the array body. The electrodes may be arranged in more than one concentric ring. A method of using an implantable stimulator includes implanting an implantable stimulator and providing an electrical signal to at least one electrode of the implantable stimulator to stimulate a tissue. The electrical signal may be provided between diametrically opposed electrodes or between electrodes that are not diametrically opposed. If the implantable stimulator has a center electrode, the electrical signal may be provided between the center electrode and at least one concentrically arranged electrode.

21. A lead comprising:
-
an array body disposed at a distal end of the lead, wherein the array body has a substantially flat, front surface; and a plurality of electrodes concentrically arranged on the substantially flat, front surface of the array body, wherein at least one electrode of the plurality of electrodes is a non-circular electrode having a major axis and a minor axis, and wherein the at least one non-circular electrode defines two linear, parallel side boundaries of that electrode and two opposing half-circle curved end boundaries of that electrode, each curved end boundary connected to the two side boundaries. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
