Abstract
A method of reducing the size of a lung by collapsing a target section of the lung includes delivering within a lung air passageway leading to the target section an intra-bronchial device. The device is deployed in a desired location and then the device is removed from the desired location. The device can be removed by gripping a portion of the device with a retractor device, which is used to draw the device proximally. Proximal movement releases anchors of the device from the passageway and the anchors can be collapsed into a removal configuration.
