US Patent 7729779 Electrodes for transcutaneous electrical nerve stimulator

A transcutaneous electric nerve stimulator (TENS) electrode that comprises a conductive layer containing both an inner perimeter(s) and an outer perimeter(s) is disclosed. When used with TENS treatment protocols and devices or other treatment/therapy methods, the electrode can induce a higher rate of A fiber firing by creating baffling to balance the electrical current flowing through the electrodes and induces superior analgesia.
