Abstract: An airway valve apparatus 10 for at least partially sealing an airway 30 of a subject 40 comprising: a hub 50; a plurality of anchor struts 60 disposed about and in communication with the hub; a plurality of support struts 70 disposed about and in communication with the hub; one or more membranes that are in communication with the plurality of anchor struts, the plurality of support struts, or both; and wherein the anchor struts include one or more anchor elements 62 disposed at a distal end of the anchor struts, the one or more anchor elements configured to engage a wall 32 of the airway.

Abstract: Devices and methods for occluding airways in at least one direction are disclosed. In some cases, the devices include anchoring mechanisms configured to keep an operative portion of the device (e.g., a valve) in position along a length of a lumen in which the device is deployed. The anchoring mechanisms can include anchors configured to settle into the lumen walls with little or no axial movement of the operative portion of the device. In some embodiments, the anchoring mechanisms include a secondary set of anchors configured to engage with the lumen wall to reduce, inhibit, or prevent axial movement of the operative portion of the device when the primary anchors settle into the walls of the lumen.
