1. An air passageway device, the device comprising:

  • an obstructing member having a distal end and a proximal end, the obstructing member comprises a support assembly having a plurality of support members, the plurality of support members extending in a proximal direction from the distal end of the obstructing member;

    a resilient membrane coupled to the plurality of support members and when deployed in an air passageway the resilient membrane is dimensioned to communicate with a portion of a lung to preclude air from being inhaled and to allow air to be exhaled;

    the air passageway device further comprising at least one anchor that anchors said obstructing member when said at least one anchor is deployed, the at least one anchor positioned entirely distal to the distal end of the obstructing member and configured to pierce into a wall of the air passageway;

    the plurality of support members comprising proximal tips that are curved toward an axial center of the obstructing member, the plurality of support members curved between the distal end of the obstructing member and the proximal tips;

    a central support structure having a distal end and a proximal end, the distal end of the central support structure coupled to the distal end of the obstructing member, the proximal end of the central support structure extending in the proximal direction through the obstructing member to provide a surface for gripping the air passageway device for removal; and

    the air passageway device configured to be collapsible for insertion into a delivery catheter and to expand upon deployment from the delivery catheter.
