Abstract: A sheath for protecting an endoscope probe projecting from an endoscope head. The sheath comprises: an elongate tube with a bore for receiving the endoscope probe; a clamp at or near a proximal end of the sheath for gripping the endoscope head or the endoscope probe; and a window which is bonded to a distal end of the elongate tube. The window is formed from an elastomeric material. An endoscope probe is inserted into the bore of the elongate tube so that it engages the window, and a force is applied so that the window is pressed and stretched against the elongate tube. The application of force causing a wall thickness of at least part of the window to decrease. The clamp comprises a resilient member with an elongate opening which can be opened to admit the endoscope probe by compressing the resilient member in line with the length of the elongate opening.

Abstract: A sheath assembly for protecting an endoscope insertion tube projecting from an endoscope head. The sheath assembly comprises: a resilient elongate tube comprising a bore for receiving the endoscope insertion tube; a resilient fitting for gripping the endoscope head; and a connector comprising a proximal end attached to the resilient fitting and a distal end attached to the tube. The connector and the resilient fitting are formed from different materials, the material forming the connector having a higher elastic modulus than the material forming the resilient fitting. The higher stiffness of the connector enables it to transmit axial forces evenly and efficiently to the fitting. The connector has a pair of laterally extending wings which provide a convenient and ergonomic point to grip the connector, making it easier to fit the assembly onto the endoscope head.
