Abstract

An improved endoscope prevents abrasion of a fiberoptic image guide with a braid reinforced sheath. Abrasion of fiberoptic image guides within articulating endoscopes quickly wear through a conventional fiberoptic mantle, decreasing the useful life of the endoscope. Preferably, the sheath comprises a metal braid disposed within a polyimide, which effectively protects the image guide from abrasion against the endoscope components and substantially extends useful life.
