Estimating the term…
An intra-bronchial device placed and anchored in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes a support structure, an obstructing member carried by the support structure that reduces ventilation to the lung portion by preventing air from being inhaled into the lung portion, and at least one anchor carried by the support structure that anchors the obstruction device within the air passageway. The anchor may engage the air passageway wall by piercing or friction, include a stop dimensioned for limiting the piercing of the air passageway wall, and may be releasable from the air passageway for removal of the intra-bronchial device. The anchors may be carried by a peripheral portion of the support structure, or by a central portion of the support structure. The obstructing member may be a one-way valve.
