Patent ID: 8175718

Claim:
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.
