Electrode patch and method for neurostimulation
First Claim
1. An electrode patch used for identifying a location on a patient'"'"'s skin for placement of a neurostimulation electrode patch on the patient'"'"'s skin to stimulate a nerve, which comprises:
- a supporting structure;
an array of electrodes mounted on the supporting structure, each electrode of the array of electrodes having a cathode and an anode and being spaced apart from each other on the supporting structure;
the patch being placeable on a patient'"'"'s skin, each electrode of the array of electrodes being individually energizable to determine the location for placement of the neurostimulation electrode patch on the patient'"'"'s skin to stimulate the nerve; and
a stimulation generator mounted on the supporting structure, the stimulation generator being electrically coupled to each of the electrodes of the array of electrodes and generating a signal including a controlled, amplitude-modulated waveform adapted for stimulating nerves, each electrode of the array of electrodes being individually energizable by the signal generated by the stimulation generator, wherein each of the individual electrodes is energized sequentially and out of phase from the other electrodes of the array of electrodes to generate a stimulation pattern to detect and locate the nerve to be stimulated.

Abstract
A system for stimulating a nerve or nerves in a patient includes an electrode patch having an array of equally spaced concentric electrodes each having a central cathode and a concentrically surrounding anode. The electrode array patch is used to determine the location of the nerve or nerves to be stimulated by electrical pulses. Once the location of the nerve is determined, a concentric electrode patch having a central cathode and a concentrically surrounding anode is positioned at the optimal location on the patient'"'"'s skin to effect neurostimulation. The concentric electrode patch may be removably affixed to the patient'"'"'s skin by adhesive or magnets.

6. A method of identifying a location on a patient'"'"'s skin for placement of a neurostimulation electrode patch on the patient'"'"'s skin to stimulate a nerve, which comprises the steps of:
-
placing an electrode patch on the patient'"'"'s skin, the electrode patch including a supporting structure and an array of electrodes mounted on the supporting structure, each electrode of the array of electrodes having a cathode and an anode and being spaced apart from each other on the supporting structure; and energizing each electrode of the array of electrodes sequentially and out of phase from the other electrodes of the array of electrodes for generating signals to stimulate the nerve and noting the patient'"'"'s response when each electrode is energized to stimulate the nerve to determine the location for placement of the neurostimulation electrode patch on the patient'"'"'s skin to stimulate the nerve.
