ABSTRACT:
A biopsy channel for a borescope or endoscope is formed of a thin-wall elastomeric tubular sleeve or sheath that is interference fitted over an expanded polytetrafluoroethylene (Teflon) liner. An end fitting can be formed of a metal or plastic tube, preferably with an internal chamfer. This can be secured by epoxy in either end of the channel, after suitably priming the elastomeric sleeve or sheath. This channel has high dimensional stability and can withstand bending to tight radii without kinking.
