Abstract
A method of using an airway assembly in an airway generally comprises providing an airway assembly having an outer tube, an inner tube disposed coaxially with the outer tube, and a seal disposed on the inner tube. The seal is inserted into the airway. The seal is moved from a collapsed position to an expanded position where the seal engages the airway. Fluid is moved through the inner tube and the seal. An additional embodiment provides the airway assembly placed in a first status. The airway assembly is inserted into an airway when the airway assembly is in the first status. The outer tube is moved with respect to the inner tube to place the airway assembly in a second status. The outer tube is moved with respect to the inner tube to place the airway assembly in a third status.
