An endoscope sheath comprising: a proximal end; a distal end having a distal end region; a surface extending between and connecting the proximal end and the distal end; and a plurality of positioning devices located along the surface; wherein the 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 sheath and the distal end of the sheath when the endoscope is inserted inside the sheath; and wherein the distal end region of the sheath includes the plurality of positioning devices that secure the cylindrical end of the endoscope against a portion of an inner wall of the surface extending between the proximal end and the distal end so that a fluid barrier is created between the cylindrical end of the endoscope and the inner wall.

1. An endoscope sheath comprising: a proximal end;a distal end having a distal end region;a surface extending between and connecting the proximal end and the distal end; and a plurality of positioning devices located along the surface; 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 sheath;wherein the distal end region of the endoscope sheath includes the plurality of positioning devices that secure the cylindrical end of the endoscope against a portion of an inner wall of the surface extending between the proximal end and the distal end so that a fluid barrier is created between the cylindrical end of the endoscope and the portion of the inner wall,wherein the plurality of positioning devices are two or more hemispherical dimples that displace the cylindrical end of the endoscope against the portion of the inner wall,wherein the endoscope sheath includes an end stop, the end stop is located at the distal end of the endoscope sheath, the end stop prevents movement of the endoscope past the distal end of the endoscope sheath when the cylindrical end of the endoscope is received in the endoscope sheath;wherein the end stop is a planar wall that is located at the distal-most end of the sheath, the planar wall extends perpendicularly to a longitudinal axis of the endoscope sheath, the end stop extends from a first side of the surface towards a second opposing side of the surface and terminates at a straight edge that is located at the distal-most end of the sheath and is located between the first side of the surface and the second opposing side of the surface, andwherein the endoscope sheath includes an opening extending at an angle from the straight edge of the end stop at the distal-most end of the endoscope sheath towards the second opposing side of the surface and towards the proximal end of the endoscope sheath,wherein a full circumferential edge of the opening lies on a single plane, andwherein the two or more hemispherical dimples are located proximate to the opening on the second opposing side and displace the endoscope from the second opposing side of the surface to the first side of the surface so that the conduit is created at the second opposing side so that irrigation fluid is moved over a viewing lens of the endoscope and the angle of the opening substantially matches an angle of the viewing lens. 2. The endoscope sheath of claim 1, wherein the portion of the inner wall is circular and the inner wall has an arc length in contact with the endoscope of about 30 degrees or more. 3. The endoscope sheath of claim 1, wherein the conduit is defined between two of the dimples, the cylindrical end of the endoscope and another portion of the inner wall.
