  • Publication number: 20190269342
    Abstract: A nerve mapping system includes an elongate medical device, a non-invasive mechanical sensor, and a processor. The elongate medical device includes a distal end portion configured to explore an intracorporeal treatment area of a subject, and the distal end portion includes an electrode. The non-invasive mechanical sensor is configured to provide a mechanomyography output signal corresponding to a monitored mechanical response of a muscle innervated by the nerve. The processor is in communication with the electrode and the sensor, and is configured to provide a plurality of electrical stimuli to the electrode. Each of the plurality of stimuli is provided when the electrode is located at a different position within the intracorporeal treatment area. The processor determines the likelihood of a nerve existing at a particular point using the magnitudes of each of the stimuli and the detected response of the muscle.

  • Patent number: 10376208
    Abstract: A nerve mapping system includes a plurality of electrodes, a sensor, and a processor in communication with each of the plurality of electrodes and the sensor. Each electrode is disposed on the distal end portion of one or more elongate medical devices configured to extend within an intracorporeal treatment area of a subject. The sensor is in communication with a muscle of a subject, and is configured to provide an output signal corresponding to a monitored response of the muscle. The processor receives an indication of the location of each electrode and an indication of a magnitude of the monitored muscular response. Using these parameters, the processor determines a distance to the nerve from the location of each of the plurality of electrodes, and constructs a virtual model of the nerve using the determined distance to the nerve at each of the plurality of locations.

  • Patent number: 10376209
    Abstract: A method of locating a nerve within an intracorporeal space includes advancing a distal end portion of a stimulator toward an anatomical target within the intracorporeal space, and periodically applying a first electrical stimulus from a first electrode disposed on a central axis of the stimulator. If a muscular response to the first electrical stimulus is detected, a locating electrical stimulus is then applied from a plurality of locations offset from the central axis of the stimulator, and a magnitude of the response of the muscle is monitored. A distance between the nerve and each of the plurality of locations is determined from the magnitude of the muscular response, and from a magnitude of the locating electrical stimulus provided at each of the plurality of locations. The location of the nerve is then triangulated from the determined distance at each of the plurality of locations.

  • Patent number: 10321833
    Abstract: A method of locating a nerve within an intracorporeal treatment area of a subject includes providing a first electrical stimulus at a first location within the intracorporeal treatment area, providing a second electrical stimulus at a second location within the intracorporeal treatment area, and providing one or more additional electrical stimuli at the second location. The first electrical stimulus does not induce a threshold response of a muscle innervated by the nerve, whereas the second electrical stimulus does induce a response of the muscle. The one or more additional stimuli each have a current magnitude less than the first stimulus and are used to determine a minimum current magnitude that is required to induce the threshold response of the muscle at the second location. This minimum current magnitude is then used to determine a distance from the second location to the nerve.
