Abstract: A disposable sheath device for use with an endoscope is disclosed. The endoscope has a body with an insertion tube having optics at its distal end. The disposable sheath device has a primary lumen and at least one secondary lumen attached to the primary lumen along a length of the lumen. The primary lumen is for covering and protecting the insertion tube from bodily contamination. The secondary lumen is for accommodating a desired tool. The secondary lumen has an insert substantially commensurate in length to the secondary lumen and the insert has a slit longitudinally along its length. The slit permits radial expansion to accommodate tools having a radius larger than that of the secondary lumen, which preferably is made of a flexible material that expands. A connector is attached to the proximal end of the primary lumen and connects to he body of the endoscope. The connector extends longitudinally to accommodate different length insertion tubes.
