Patent number: 11850057Abstract: A method of alerting a user to an artificially induced neuromuscular response in a subject includes generating a mechanomyography (MMG) output signal corresponding to a mechanical motion of a muscle of a subject, applying a wavelet transform to the MMG output signal to determine a convolution coefficient for each of a plurality of daughter wavelets, summing the convolution coefficients determined across the plurality of daughter wavelets at each timestep across a plurality of timesteps to generate a net-convolution coefficient (NCC), identifying one or more peaks in the NCC via a peak finding algorithm, and alerting a user of an artificially induced neuromuscular response following the identification of one or more peaks in the NCC. Each daughter wavelet of the plurality of daughter wavelets is a time-scaled variant of a common mother wavelet, and the convolution coefficient is indicative of a similarity between the daughter wavelet and the MMG output signal.Type: GrantFiled: May 19, 2023Date of Patent: December 26, 2023Assignee: NEURALYTIX, LLCInventors: Christopher Wybo, David S.

Patent number: 10376209Abstract: 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.Type: GrantFiled: October 5, 2016Date of Patent: August 13, 2019Assignee: Innovative Surgical Solutions, LLCInventor: Christopher Wybo

Patent number: 10321833Abstract: 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.Type: GrantFiled: October 5, 2016Date of Patent: June 18, 2019Assignee: Innovative Surgical Solutions.Inventor: Christopher Wybo
