Q: What is "duckbill" mechanism?

Answer: "Duckbill" mechanism is applied in the IntraBronchial Valve (IBV) which allows air and secretions to pass through a central orifice that opens during exhalation but stay close on inhalation preventing air to enter. It is a kind of a non-surgical version of  lung volume reduction surgery (LVRS) for severe emphysema.
