  • Method and apparatus for quantitative nerve localization
    Patent number: 9042978
    Abstract: A method for localizing a needle to a nerve, the method comprising: using the needle to electrically stimulate the nerve, with a known current intensity, so as to evoke a nerve response; detecting the nerve response; analyzing the detected nerve response so as to identify at least one attribute of the same; and confirming that the needle is in the immediate proximity of the nerve based upon known current intensity and at least one identified attribute of the detected nerve response.
    Type: Grant
    Filed: May 29, 2009
    Date of Patent: May 26, 2015
    Assignee: NeuroMetrix, Inc.
    Inventors: Changwang Wu, Shai Gozani, Xuan Kong

  • Non-invasive acquisition of large nerve action potentials (NAPs) with closely spaced surface electrodes and reduced stimulus artifacts
    Publication number: 20080051647
    Abstract: The present invention addresses the foregoing problems associated with the prior art by providing a novel method and apparatus for, non-invasively detecting large nerve action potentials (NAPs) while effectively minimizing or substantially eliminating stimulus artifacts, even where the stimulation site and the detection site are in close physical proximity to one another, e.g., within about 2 cm of one another.
