Patent ID: 8308743

Claim:
A clipping device comprising: a sheath member to be inserted in the body of the patient; an actuating wire received in the sheath member so as to be longitudinally movable relative to the sheath member; a clip unit attached to the clipping device in advance and having a tissue clip for clipping in the body of the patient and a coupling member arranged at a distal end of the actuating wire; wherein: the coupling member includes a first end fastened to the distal end of the actuating wire to be immovable in an axial direction of the actuating wire and a direction deviating from the axial direction and a second end attached to the tissue clip; and when applying the tissue clip, the second end of the coupling member is deformable upon exertion of a force in a proximal direction at the first end of the coupling member that is greater than a predetermined amount so as to prevent a subsequent attachment of the second end to another tissue clip.
