A neural stimulator includes an electrically non-conductive carrier and at
least two electrically conductive electrodes disposed on opposite sides
of the carrier. The electrodes on the opposite sides of the carrier are
not electrically connected together. Instead, a signal source is
connected to one of the electrodes on one side of the carrier and a
return path to the signal source is connected to a corresponding
electrode on the other side of the carrier. The corresponding electrode
can, but need not be, directly opposite the electrode on the other side
of the carrier. The electrodes can be rings, disks, other shapes or
combinations thereof. Optionally, the carrier includes low-impedance
shunts therethrough.
