Abstract:
1. An intra-bronchial device for placement in an air passageway of a patient, the device comprising: a support structure comprising a longitudinal axis extending between a distal end and a proximal end, a central member extending longitudinally from the distal end to the proximal end through an axial center of the device, the central member configured to be engaged by a removal device; an obstructing member comprising a resilient membrane that precludes fluid flow through said resilient membrane, the obstructing member being carried by the support structure and the obstructing member preventing air from being inhaled into a lung portion to collapse the lung portion, at least a portion of the central member being surrounded by the resilient membrane; and at least a first anchor at the distal end and a second anchor at the proximal end, the first and second anchors carried by the support structure that anchor the device within the air passageway when the anchors are deployed, the first anchor comprises a first tip and a second tip, and a distance defined between the first tip and the second tip when the anchors are deployed, and the first and the second anchors being configured to fold toward the longitudinal axis in a direction that moves the anchors away from the obstructing member without increasing the distance when the central member is engaged by the removal device.
