Abstract

A bronchoscopic sheath adapted to be fit over the outside surface of the proximal portion of a bronchoscope to assist with measuring or spacing of treatment. The measurement or spacing sheath is preferably made of braided polymer filament and is configured to collapse under tension and open/expand when the ends of the sheath are pushed towards one-another. Markings are provided on the sheath at regular intervals to reflect distance. The markings may be woven into the braid, or printed on the exterior of the braid. The proximal end of the sheath may be flared and the distal end may be tapered. Each end may be provided with a cuff that may be part of the braid, or a separate elastomeric material, or a thermally sealed edge with atraumatic tip.
