Abstract

An intra-bronchial device may be placed and anchored in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes an obstructing member that prevents air from being inhaled into the lung portion, and an anchor that anchors the obstruction device within the air passageway. The anchor may piercingly engage the air passageway wall. The anchor may be releasable from the air passageway for removal of the obstructing member. The anchor may be releasable by collapsing a portion of the obstructing member, or by drawing the obstructing member toward the larynx. The obstructing member may be a one-way valve.
