  • Publication number: 20230000473
    Abstract: According to embodiments, a substantially coaxial arrangement of a camera, a light source, and an ultrasonic sensor can be positioned in an housing of a system that can be deployed from the tool port of a standard bronchoscope. Illumination from the light source facilitates positioning of the system by an operator using information from the camera. The ultrasonic system can determine when an object to be biopsied is adjacent to a biopsy needle.

  • Publication number: 20220104797
    Abstract: The disclosure describes a lung biopsy system including an elongated housing extending from a proximal end to a distal end, at least one biopsy needle guide lumen extending within the housing, the guide lumen configured to enable deployment of a biopsy needle and extending from a proximal portion of the housing to a biopsy port in the housing, the biopsy port being positioned proximal to the distal end, a camera configured to be arranged in the housing to obtain optical data relating to a position of the system, a light source configured to be arranged in the housing adjacent to the camera to produce illumination for the camera; and one or more electrodes carried by the housing and positioned adjacent to the biopsy port, the one or more electrodes configured to measure an impedance of a surrounding tissue of a patient.

  • Publication number: 20190374374
    Abstract: A graphical user interface is used to provide training to conduct vocal exercises and provide feedback in order to reduce snoring and/or obstructive sleep apnea. The vocal exercises are associated with, for example, strength, coordination, and endurance for muscles and nerve control associated with sleep apnea or snoring. This summary is not intended to describe each embodiment or every implementation of the subject matter hereof. The figures and the detailed description more particularly exemplify various embodiments.

  • Patent number: 8686171
    Abstract: The present invention relates to methods and apparatus for producing alkyl esters from lipid feed stocks, such as plant oils and/or animal fats, and systems including the same. In an embodiment, the invention includes a process for producing alkyl esters including mixing a lipid feed stock with an alcohol to form a reaction mixture; and contacting the reaction mixture with a catalyst under supercritical conditions for the alcohol, the catalyst comprising an unmodified metal oxide selected from the group consisting of alumina, titania, zirconia, and hafnia, and removing residual free fatty acids from the reaction mixture. Other embodiments are included herein.
