Patent ID: 7434578

Claim:
A method of reducing the size of a lung by collapsing a target section of the lung, the method including the steps of: delivering within a lung air passageway leading to the target section an intra-bronchial valve device having an obstructing member supported on a support structure, the obstructing member being configured to preclude air from being inhaled into the target section, while allowing air to be exhaled from the target section, the valve device further comprising at least one anchor member carried by the support structure; deploying the valve device at a desired location within the air passageway so as to cause the at least one anchor member to move from a delivered state in which the anchor member is spaced from an air passageway wall to an anchored state in which the anchor engages the wall; and releasing the at least one anchor from engagement with the air passageway wall and removing the valve device from the desired location by engaging an anchor base aperture portion of an anchor base.
