An intra-bronchial device may be placed 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 to collapse the lung portion, and an anchoring device that anchors the obstructing member in the air passageway by engaging the obstructing member and the air passageway wall. The anchoring device may frictionally engage the obstructing member and the air passageway, or engage both by piercing. The engagement provided by the anchoring device may be releasable for removal of the obstructing member. The anchoring device may be balloon expandable from a first shape to a second shape that engages the obstructing member and the air passageway. The obstructing member may be a one-way valve. |
