REMOVABLE ANCHORED LUNG VOLUME REDUCTION DEVICES AND METHODS

摘要

An intra-bronchial device (100) may be placed and anchored in an air passageway (50) of a patient to collapse a lung portion associated with the air passageway. The device includes an obstructing member (110) that prevent s air from being inhaled into the lung portion, and an anchor (112) that ancho rs the obstruction device (110) within the air passageway. The anchor (112) may piercingly engage the air passageway wall. The anchor (112) may be releasabl e from the air passageway wall. The anchor (112) may be releasable from the ai r passageway for removal of the obstructing member (110). The anchor (112) may be releasable by collapsing a portion of the obstructing member (110), or by drawing the obstructing member toward the larynx. The obstructing member (11 0) may be a one-way valve.
