  • Neural Sleeve for Neuromuscular Stimulation, Sensing and Recording

    US20150306373A1 · Oct 28, 2015
    Inventors: Chad E. Bouton, J Friend, Gaurav Sharma, Nicholas V. Annetta, Steve Risser
    The present disclosure relates to neuromuscular stimulation and sensing cuffs. The neuromuscular stimulation cuff has at least two fingers and a plurality of electrodes disposed on each finger. More generally, the neuromuscular stimulation cuff includes an outer, reusable component and an inner, disposable component. One or more electrodes are housed within the reusable component. The neuromuscular stimulation cuff may be produced by providing an insulating Substrate layer, forming a conductive circuit on the Substrate layer to form a conductive circuit layer, adhering a cover layer onto the conductive circuit layer to form a flexible circuit, and cutting at least one flexible finger from the flexible circuit. The neuromuscular stimulation cuff employs a flexible multi electrode design which allows for reanimation of complex muscle movements in a patient, including individual finger movement.
  • Systeme für die neürale überbruckung des nervensystems

    EP3302688A1 · Jun 2, 2016
    Inventors: Chad E. Bouton, Nicholas V. Annetta, David Friedenberg, Gaurav Sharma
    The present disclosure relates generally to systems, methods, and devices for interpreting neural signals to determine a desired movement of a target, transmitting electrical signals to the target, and dynamically monitoring subsequent neural signals or movement of the target to change the signal being delivered if necessary, so that the desired movement is achieved. In particular, the neural signals are decoded using a feature extractor, decoder(s) and a body state observer to determine the electrical signals that should be sent.
  • Closed Loop Deep Brain Stimulation Systems and Methods

    WO2016196790A1 · Dec 7, 2016
    Inventors: Chad E. Bouton, Gaurav Sharma, Bradley Glenn

    The present disclosure relates generally to systems, methods, and devices for closed loop deep brain stimulation. In particular, a neural signal is measured and provided to software. The software includes a feature generator and a brain network model that takes the neural signal and estimates other neural signals that are not directly measured, and operates as a model of the brain. The software determines a stimulation signal to be sent to stimulating electrodes. Estimated signals by the brain network model are continuously compared to actual signals from the brain. The closed loop feedback system advantageously allows for electrical stimulation levels and patterns to be continuously updated while delivered to a patient.

  • Non-Invasive Eye-Tracking Control of Neuromuscular Stimulation System

    WO2017/205476Al · May 23, 2017
    Inventors: David Friedenberg, Gaurav Sharma, Chad E. Bouton

    A non-invasive control system for neuromuscular stimulation includes an 100 eye-tracking device, an electrical stimulation device, and software that interprets the eye movements of the user to determine an intended movement and sends electrical signal(s). Eye Tracking to the stimulation device to achieve the intended movement. For example, the stimulation. Device 110 device may be a sleeve with electrodes worn on a paralyzed limb, with the intended movement being the movement of the limb.

  • Implant with Reactive Oxygen Species Scavenging Coating

    US20180078681A1 · Mar 21, 2018
    Inventors:

    A chronically implanted medical device is disclosed that has an outermost layer formed from a conjugate of a polymer with lipoic acid, the conjugate having free 1, 2 - dithiolane groups. It is contemplated that this layer scavenges reactive oxygen species, i. e. acts as an antioxidant, and thus reduces inflammation and other adverse effects around the implant itself.
