Abstract
A surgical sheath for use in endoscopic trans-nasal or intra-ocular surgery is made of a braid material. The sheath may be manufactured by placing a length of braided tube material over a mandrel. The braid material is conformed to the shape of the mandrel and is then heat set. An atraumatic end may be made by folding or rolling one or both ends of the sheath. A coating may also optionally be applied to the braid material. The sheath reduces collateral trauma to the tissues in the surgical pathway.
