  • 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: 20190269535
    Abstract: A central airway stent removal device for use under direct visual observation with a flexible or ridged. The device includes an elongated shaft defining a central lumen configured to receive the endoscope and a hook mechanism attached to a distal end of the elongated shaft. The hook mechanism including a receiving platform extending away from the elongated shaft and a hook element at the distal end of the hook mechanism, the hook element defining a receiving slot having an entrance that opens towards the elongated shaft, in which the receiving slot is configured to receive an end of a stent intended to be removed from a body of a patient.
