A protective covering (30) for a medical instrument, such as an endoscope (10), is described. The covering (30) includes an elongated hollow sheath (36) having a wall of flexible material. The sheath (36) is substantially gas and water impervious. The sheath (36) further includes auxiliary access tubes associated with the sheath (36) for providing a variety of functions, such as instrument manipulation, and fluid removal. The distal end (38) of the sheath (36) is provided with a cap (40) having an optically clear window (48) to allow the lens portion of the medical instrument (10) to operate. |
