  • Patent number: 12636422
    Abstract: A balloon dilation catheter includes a substantially rigid inner guide member and a movable shaft coupled to a balloon that is slidably mounted on the substantially rigid inner guide member. To treat a sinus cavity of a subject using the balloon dilation the substantially rigid inner guide member is advanced into a drainage pathway of the sinus (e.g., frontal recess or maxillary sinus) of the subject via a nasal passageway. The shaft and balloon are advanced in a distal direction over the substantially rigid inner guide member to place the balloon in the drainage pathway. The balloon is inflated to expand or otherwise remodel the drainage pathway.

  • Publication number: 20240023648
    Abstract: In an example, a mask includes a containment wall, a gasket, a nasal access in the containment wall, an inlet, and an outlet. The containment wall includes an inner surface, an outer surface opposite the inner surface, and a peripheral edge at an interface between the inner surface and the outer surface. The gasket is at the peripheral edge of the containment wall. The gasket can conform to the face of a wearer. The containment wall and the gasket define a chamber between the inner surface of the containment wall and the face of the wearer when the mask is worn by the wearer. The nasal access opening is aligned with a nose of the wearer when the mask is worn by the wearer. The inlet can receive a gas into the chamber. The outlet can exhaust out of the chamber the gas and aerosols exhaled by the wearer.
