Abstract
A device for non-invasively locating the presence of peripheral nerves. The peripheral nerve mapping device has a sampling electrode comprising an array of a plurality of sub-electrodes, a reference electrode, a square wave constant current source, and a multiplexer serially multiplexed to the array of the sub-electrodes. The voltage differential between each of the sub-electrodes and the reference electrode is measured as the current is serially distributed to the sub-electrodes and displayed on an array of light emitting diodes. The voltage differential indicates the presence of peripheral nerves and may be used to identify sites of nerve trauma or transection.
