ABSTRACT:
Sterile disposable coverings for endoscopes and similar optical medical instruments are disclosed together with a method for preparing such coverings. By forming a heated polymeric film with a mandrel of appropriate shape and dimensions, relatively long-length, very small diameter, closely-fitting, thin-walled sleeves are produced, each having a thin, substantially inelastic, optically transparent window formed continuously integral with the sleeve at or proximate to the closed, distal end of the sleeve.
