Sheath and method for reconfiguring lung viewing scope
First Claim
1. A method for accessing and occluding a lung passageway, said method comprising:
- providing a viewing scope comprising a flexible elongated body, an optical viewing element, and a light transmitting bundle;
providing a sheath comprising a flexible tubular body having a proximal end, a distal end, at least a first lumen therethrough, and at least a first inflatable cuff disposed near the distal end;
introducing the viewing scope into the lumen of the flexible tubular body of the sheath to form an assembly where a viewing end of the viewing scope is located at the distal end of the sheath;
introducing the assembly of the viewing scope and sheath to a lung passageway so that the inflatable cuff lies adjacent to a target location in the passageway;
inflating the cuff to temporarily occlude the target location; and
advancing a plug element through a lumen of the view scope to the target location.

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.
