1. A method of treating a lung, comprising:
- providing a flow control device, the flow control device comprising a frame adapted to self-expand from a contracted configuration to an expanded configuration, the frame coupled to a membrane;
inserting the flow control device in a bronchial passageway such that the frame self-expands within the bronchial passageway and the membrane seals with a wall of the bronchial passageway so that the flow control element prohibits air from flowing past the flow control element in an inhalation direction within the bronchial passageway and also prohibits air from flowing past the flow control element in an exhalation direction within the bronchial passageway.

Abstract
An obturator for a bronchial tube or tubule of a human or animal lung comprises a blocking element (92) and a securing element (90). The blocking element serves to seal the tube or tubule against the passage of fluid past the obturator when the obturator is disposed in a bronchial tube or tubule. The securing element serves to retain the blocking element in position. The blocking element comprises a substantially cylindrical plug of biocompatible, resiliently deformable closed-cell foamed plastics material, such as PVC. The securing element comprises a stent having barbs (98) to engage and retain the blocking element. The stent also has anchors (100) to retain the stent in a bronchial tube or tubule. A method of treatment of emphysema or other lung conditions or diseases in human or animal patients comprises placing an obturator in a bronchial tube or tubule of the patient so as to seal the tube or tubule against the passage of fluid past the obturator.
