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.

Abstract: The sheath includes a protruding section that protrudes from a ring-shaped distal end surface of a sheath body and a lifting part that lifts the protruding section within the pericardial cavity to a position separated from the surface of the heart toward the pericardium. The protruding section includes a pressing surface disposed toward the pericardium when the protruding section is lifted by the lifting part, and also includes an opening that is provided at a position facing the pressing surface in a radial direction and at which a distal end surface of the endoscope is capable of appearing in the radial direction as an endoscope bending section operates.

Abstract: An atrial appendage ligation surgical tool that includes: a tubular loop shaft having an inner hole that penetrates therethrough in a longitudinal direction; and a ligature loop that is in an inserted state in the inner hole of the loop shaft and formed of a wire that forms a loop closed with a knot at a distal end of the loop shaft, the loop being contractible in size by being pulled from a proximal end of the loop shaft. The ligature loop is given a tendency to form a flat ring-shaped loop having a size an atrial appendage is insertable when in a free state, and the knot is placed near an end of the loop in a long axis direction thereof.
