1. An endoscope sheath comprising:
a proximal end defining a proximal opening along a longitudinal axis of the endoscope sheath;
a distal end defining a distal opening along the longitudinal axis of the endoscope sheath;
an inner wall extending between and connecting the proximal end and the distal end; and
a plurality of positioning devices located along the inner wall, the plurality of positioning devices including two distal positioning devices equally spaced apart around the inner wall and three proximal positioning devices equally spaced apart around the inner wall, wherein the distal positioning devices and the proximal positioning devices are circumferentially offset such that circumferential positions of the distal positioning devices do not overlap with circumferential positions of the proximal positioning devices when viewed from the distal end of the endoscope sheath;
wherein the endoscope sheath is configured to:
(1) receive all or a portion of an endoscope having a cylindrical end; and
(2) provide a conduit for communicating fluid between the proximal end of the endoscope sheath and the distal end of the endoscope sheath when the endoscope is inserted inside the endoscope sheath; and
wherein the plurality of positioning devices is configured to create a circumferential gap between an outer surface of the endoscope and the inner wall of the endoscope sheath and to prevent distal advancement of the endoscope beyond the distal end of the endoscope sheath.
