ABSTRACT:
This is directed to improving the gaseous exchange in a lung of an individual and particularly, this is directed to improving the gaseous exchange in individuals having chronic obstructive pulmonary disease. It generally includes fluidly connecting the lung to an extrapleural airway such as the trachea. In one variation, a conduit is deployed to place the lung and the trachea in fluid communication which allows trapped oxygen-reduced air to pass directly out of the lung and into the trachea. Removing nonfunctional air from the lung tends to improve the gaseous exchange of oxygen into the blood and decompress hyper-inflated lungs. Sealant and biocompatible adhesives may be provided on the exterior of the conduit to prevent side flow, leaks and to otherwise prevent air from entering spaces not intended to receive air such as the pleura space.
