Abstract
An improved method and device for locating a nerve based on a closed-loop automated system is described. The device applies an electro-stimulus to a target tissue area and measures and interprets a change in a response evoked by application of an electro-stimulus to determine the location and responsiveness of a nerve. The improvement of the invention comprises a method for determining if the signal of the response is stable prior to application of electro-stimulation to prevent misinterpretation of a response and to enhance the locating accuracy of the device.
