摘要：
A sheath assembly for an endoscope includesan elongate tubular body and a plug. The endoscope has ahandle portion and a scope portion extending therefrom to atip. The body includes first (40) and second (42) wall sectionsand extends along a longitudinal axis between first andsecond distal openings located at distal and proximal endsthereof, respectively. The first wall section (40) extends radiallyabout the longitudinal axis to define a scope lumen (44).The scope portion is receivable in the scope lumen with thedistal and proximal ends. The second wall section (42) extendsradially about a portion of the first wall section (40) andlongitudinally between second distal and proximal end openings.The first and second wall sections define an integral suctionlumen (50) in fluid communication with a first source ofnegative pressure. The plug is mated with the distal end openingand includes a lens surface through which energy is transmissible.
