Abstract
Apparatus, methods, and kits, are provided for use in combination with a conventional bronchoscope or other lung viewing scope. In particular, sheaths having an inflatable cuff at their distal end are provided to receive a viewing scope through a lumen thereof. The sheaths thus provide an inflatable cuff on a viewing scope assembly so that the scope can be used in procedures which require selective isolation of regions of a patient's lungs. In particular embodiments, the sheaths may include stop elements for properly positioning a viewing scope therein, pressure transducers for providing accurate lung pressure information during procedures, and the like. Methods for using and forming sheaths having inflatable cuffs are also described.
