摘要： Devices and related methods are directed to altering gaseous flow within a lung to improve the expiration cycle of, for instance, an individual having Chronic Obstructive Pulmonary Disease. More particularly, conduits maintain collateral openings or channels through the airway wall so that air is able to pass directly out of the lung tissue to facilitate both the exchange of oxygen ultimately into the blood and/or to decompress hyper-inflated lungs. The conduits include a center section with a passageway extending through the center section. The conduits further include a distal cage structure which has a passageway and at least one opening in fluid communication with the center section passageway. The medical kits disclosed herein are also directed to maintain collateral openings through airway walls.

摘要： Devices and methods are directed to improving the gaseous exchange in a lung (118) of an individual having, for instance, chronic obstructive pulmonary disease. More particularly, conduits (200) may be deployed in the lung to maintain collateral openings or channels (112) surgically created through airway (100) walls. This tends to facilitate both the exchange of oxygen ultimately into the blood and decompress hyper-inflated lungs. The conduit (112) includes a radially expandable center section having a first end, a second end, and a passageway extending from the first end to the second end. A control segment may be associated with the conduit to limit the degree of radial expansion. The conduit further includes a plurality of deflectable members extending from the ends of the center section. A tissue barrier may coaxially surround the conduit such that tissue ingrowth is prevented.
