Patent ID: 7875048

Claim:
An intra-bronchial device for placement in an air passageway of a lung, the device comprising: a generally umbrella-shaped obstructing member configured when deployed to substantially seal and preclude air from being inhaled into an air passageway while allowing fluid to flow past and around the obstructing member in an expiratory direction through the air passageway; a first anchor positioned distally of the mid-point of the obstructing member and terminating at a plurality of first anchor tips; a second anchor positioned proximally of the mid-point of the obstructing member and terminating at a plurality of second anchor tips; and a support structure having a distal end and a proximal end, the support structure positioned between the first anchor and the second anchor, wherein at least one of the first anchor tips is positioned distally to the distal end of the support structure; wherein the first and the second anchors are configured to prevent substantial migration of the device within the air passageway when the anchors are deployed, and are releasable to permit removal of the device from said passageway.
