  • Publication number: 20240188879
    Abstract: A system and method of detecting eye movements of a subject for the diagnosis of neurological disorders. The method includes tracking eye movements of the subject, identifying microsaccades from the tracked eye movements, and characterizing microsaccade dynamics of the identified microsaccades to determine one or more parameters, such as microsaccade direction, microsaccade velocity, microsaccade magnitude, microsaccadic peak velocity-magnitude relationship, microsaccade duration, and intersaccadic intervals. The method also includes comparing the one or more determined parameters with a corresponding control parameter, assessing the comparison to determine differences between the one or more determined parameters and the corresponding control parameters, and generating a report including the diagnosis of neurological disorder based on the assessment.

  • Patent number: 11850166
    Abstract: Various embodiments of an expandable interbody cage device configured to reduce subsidence into an endplate of a vertebral body by including a plurality of arms that engage the cortical tissue of the vertebral body. The plurality of arms increase the surface area and improve distribution of force, especially around stronger parts of the endplate such as the cortical bone at the rim of the endplate. The expandable interbody cage device maintains a low or slim profile while in a “closed” configuration during insertion between vertebrae and is further operable to laterally expand into an “open” configuration that increases the surface area of the expandable interbody cage device after insertion to securely engage the expandable interbody cage device between the vertebra. The expandable interbody cage device further includes one or more ports and/or cavities in which bone graft material can be disposed within.

  • Patent number: 11771902
    Abstract: Disclosed herein are methods, systems, and apparatus for treating a medical condition of a patient, involving detecting a physiological cycle or cycles of the patient and applying an electrical signal to a portion of the patient's vagus nerve through an electrode at a selected point in the physiological cycle(s). The physiological cycle can be the cardiac and/or respiratory cycle. The selected point can be a point in the cardiac cycle correlated with increased afferent conduction on the vagus nerve, such as a point from about 10 msec to about 800 msec after an R-wave of the patient's ECG, optionally during inspiration by the patient. The selected point can be a point in the cardiac cycle when said applying increases heart rate variability, such as a point from about 10 msec to about 800 msec after an R-wave of the patient's ECG, optionally during expiration by the patient.

  • Patent number: 11759134
    Abstract: Systems and methods for detecting deceptive intent of a subject include observing eye movements of the subject and correlating the observed movements to known baseline neurophysiological indicators of deception. A detection system may record eye movement data from the subject, compare the eye movement data to a data model comprising threshold eye movement data samples, and from the comparison make a determination whether or not the subject is lying. The detection system may create an alert if deception is detected. The eye movements detected include saccadic and intersaccadic parameters such as intersaccadic drift velocity. Measurements may be collected in situ with a field testing device, such as a non-invasive, non-contact device attached to the subject's computing device and configured to non-obtrusively record the eye movement data.
