Abstract: Provided is an endoscope sheath including an elongated body having flexibility, the body having a first lumen through which an endoscope passes in a longitudinal direction of the body and a second lumen through which a guide wire passes in the longitudinal direction. A direction in which the second lumen opens at the distal end of the body gradually diverges from a direction in which the first lumen opens at the distal end, in a forward direction from the distal end.

Abstract: Even if atrial-appendage tissue is damaged due to an excessive force unintentionally exerted during ligation of the atrial appendage, the effect of the damage is minimized. Provided is an atrial-appendage ligation treatment tool that is used, together with an atrial-appendage ligation tool having a ligation part, to perform atrial-appendage ligation treatment. The atrial-appendage ligation treatment tool includes: a compressing portion that is introduced, separately from the ligation part, to a cardiac sac through a sheath penetrated through a pericardium and that compresses the atrial appendage from outside to occlude an internal space therein; and a shaft that is disposed in the sheath in an inserted manner and that supports, at a distal end thereof, the compressing portion.
