Abstract
A partially elastic protective sheath surrounding the insertion tube of an endoscope. The sheath is partially inflated while being installed on the endoscope and remains partially inflated during endoscopy. The sheath has an end cap with a gasket shaped to provide a seal around the insertion tube during installation and endoscopy. The sheath is provided with a window near its distal end positioned in front of the viewing window of the endoscope. The sheath may have one or more channels extending along its length to accommodate one or more biopsy or fluid tubes of the endoscope. The sheath may be used with either end-viewing endoscopes or side-viewing endoscopes.
