38. A method of regulating fluid flow to and from a region of an individual'"'"'s lung, comprising:
-
placing a flow control device in a bronchial passage in communication with the region, the flow control device having a first set of one or more deployable arms in a collapsed configuration; and
radially expanding the first set of one or more deployable arms into engagement with a wall of the bronchial passage to anchor the flow control device therein;
wherein the flow control device has a plurality of overlapping segments that are movable relative to one another and collectively form a seal with a wall of the bronchial lumen that can expand and contract in size. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)

52. A flow control device for placement in a body lumen comprising:
-
a frame comprising a plurality of struts connected to a distal hub, at least a portion of each strut biased outwardly from the distal hub; and
a membrane coupled to the struts thereby forming an umbrella shape, wherein the frame urges the membrane into engagement with a wall of the body lumen to form a seal therewith. - View Dependent Claims (53, 54, 55, 69, 70, 71, 72, 73)
