1. An electrode for use in monitoring motor evoked potentials during spinal surgery comprising:
- an elongate strip;
a conductive track on the first surface of said strip, the conductive track being adapted for electrical connection with a lead;
a conductive track on the second surface of said strip in electrical contact with the track on the top surface of said strip through a plated-through hole; and
said strip being comprised of a thin, flexible, electrically non-conductive material.

Abstract
An electrode for use in monitoring MEPs during spinal instrumentation. A thin, flexible strip of insulative material is provided with conductive tracks on both top and bottom surfaces, the top and bottom conductive tracks connecting through respective plated-through holes. The bottom side tracks extend at an oblique angle relative to the top side tracks and are spaced apart so as to provide intimate contact with the surface of the dura against which the electrode is placed during surgical procedures. The top side tracks terminate in a solder pad to which leads for the instrumentation for measuring/detecting MEPs are connected.
