Patent ID: 8021385

Claim:
A method of treating a lung, the method comprising: providing an air passageway 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, a resilient membrane coupled to the support members and when deployed in an air passageway the resilient membrane is dimensioned to communicate with a portion of the lung to preclude air from being inhaled, said air passageway device further comprising at least one anchor that anchors said obstructing member when said anchor is deployed, the at least one anchor positioned distal to the distal end of the obstructing member, 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 and the proximal tips to form a concave side and convex side, wherein the concave side faces the axial center of the obstructing member and the convex side faces a wall of the air passageway; placing said obstructing member in the air passageway with a delivery catheter; deploying said anchor; and disengaging said delivery catheter from said obstructing member, wherein said obstructing member substantially precludes air from being inhaled after said delivery catheter is disengaged from said obstructing member.
