<p>An improved endoscope prevents abrasion of a fiberoptic image guide (18) with a braid reinforced sheath (32). 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 (32) comprises a metal braid (42) disposed within a polyimide (40, 44) which effectively protects the image guide from abrasion against the endoscope components and substantially extends useful life.</p> |
