  • Patent number: 11826157
    Abstract: Embodiments of a method for removal and replacement of artifacts in electrophysiological data from muscular activity in the gastrointestinal tract of a patient are disclosed. The approach includes setting an artifact identification threshold based on the parameters of the data, assessing the full extent of the artifact in time, and replacing the values with ones that are neutral in the time series and minimizing the effect on a power spectrum of the data. More particularly, the method includes steps of identifying artifacts within the raw time series data, eliminating the identified artifacts, and replacing the artifacts with any of interpolated points or constant value points to create a clean time series data set representing valid gastrointestinal tract EMG signals.

    Abstract: A method for identifying and treating a neural pathway associated with chronic pain via nerve stimulation and brain wave monitoring of a mammalian brain is described. The method includes positioning a probe to stimulate a target nerve, wherein the target nerve is suspected of being a source of chronic pain; delivering a first nerve stimulation from the probe to the target nerve, wherein the first nerve stimulation is sufficient to elicit a chronic pain response in the brain; and monitoring for evoked potential activity in the brain as a result of the first nerve stimulation. The method can also include delivering second and third nerve stimulations to confirm the correct identification of the neural pathway and to treat the chronic pain, respectively. A system and apparatus for performing a procedure to identify and treat a nerve that is the source of chronic pain are also described.

  • Patent number: 11491276
    Abstract: Release of a neurological drug in a targeted region of a subject's brain by a drug delivery system (DDS) is intentionally caused by the subject watching or interacting with an audio/video-based task on an electronic display. The DDS is calibrated to release the neurological drug based on a particular pH, lactate level, blood flow, temperature, magnetic field, specific molecules released by brain cells, or other physiological factors within the target region. The interactive task produces the physiological factors in the brain in specific areas of pathology for which the drug is prescribed, and limits drug delivery at areas unaffected by illness where it could disrupt normal function, causing problematic side effects and preventing dose levels optimal for target impact. Feedback from the interactive task and associated cognitive probes also can adapt the interactive task or suggest new pharmacologic agents as the degree or primary focus of brain pathology changes during the course of treatment.

  • Patent number: 11041198
    Abstract: A method of forming a plurality of lipid bilayers over an array of cells in a nanopore based sequencing chip is disclosed. Each of the cells comprises a well. A salt buffer solution is flowed over the array of cells in the nanopore based sequencing chip to substantially fill the wells in the cells with the salt buffer solution. A lipid and solvent mixture is flowed over the array of cells to deposit the lipid and solvent mixture over at least some of the wells in the cells. A first portion of the cells, each having a lipid bilayer over its well, is detected. A second portion of the cells, each having a lipid membrane but not a lipid bilayer over its well, is detected. An electrical lipid-thinning stimulus is selectively applied to the second portion of the cells but not to the first portion of the cells.

  • Patent number: 10939867
    Abstract: A paralysis monitoring system can be utilized during various medical procedures. Generally, the system is used during procedures involving anesthesia, when general paralysis is necessary, e.g., during surgery that requires cutting through or mobilizing muscle tissue. The paralysis monitoring system stimulates a nerve with low voltage signals and can provide for continuous monitoring and recording of the evoked muscle activity throughout and after a procedure. By monitoring a quantitative response of the muscle activity to nerve stimulation, an anesthesiologist may adjust subsequent doses of a paralytic agent to achieve a desired level of paralysis.

  • Patent number: 10924869
    Abstract: A sound processing system measures one or more periauricular muscle signals from one or more periauricular muscles of a user. Additionally, the sound processing system computes, based on the periauricular muscle signals, an estimate of an angle corresponding to a direction of a current auditory attention locus of the user with respect to a reference point or plane. The sound processing system controls, based on the estimate of the angle, an operating characteristic of the sound processing system.

  • Patent number: 10814166
    Abstract: A wearable device has a core contraction sensor. Signals from the core contraction sensor are transmitted to a processor which analyzes the core contraction signals and determines if the user's core is contracted or relaxed. The processor can cause a computing device to output a sequence of tones in response to a core contraction signal. The sequence of tones can correspond to a song which can be played by performing a plurality of core contractions with durations that correspond to a duration of the notes in the song. Alternatively, the core muscles can be contracted to correspond to music heard by the user. The processor can output a score based upon the matching of the core contractions with the musical notes.
