  • Patent number: 11202559
    Abstract: The present disclosure includes vision preservation systems for medical devices, such as cryospray devices for use with endoscopes. Exemplary embodiments provide a distal attachment in the form of a shroud or cap that mounts to the end of a flexible endoscope. A purging fluid supply mechanism is provided along the length of the endoscope, providing a channel for purging fluid, such as gas, to communicate between the endoscope tip and an external gas supply. The cap or shroud assembly incorporates a lens clearing flow field adjustment mechanism, such as nozzles, designed to direct warm (room temperature or higher) purging fluid across a lens at the scope tip. Another flow deflection mechanism, such as a guide or nozzle, may be included with the cap to direct purging fluid at an angle away from the lens.

  • Patent number: 11019986
    Abstract: A bronchoscopic sheath adapted to be fit over the outside surface of the proximal portion of a bronchoscope to assist with measuring or spacing of treatment. The measurement or spacing sheath is preferably made of braided polymer filament and is configured to collapse under tension and open/expand when the ends of the sheath are pushed towards one-another. Markings are provided on the sheath at regular intervals to reflect distance. The markings may be woven into the braid, or printed on the exterior of the braid. The proximal end of the sheath may be flared and the distal end may be tapered. Each end may be provided with a cuff that may be part of the braid, or a separate elastomeric material, or a thermally sealed edge with atraumatic tip.
