Abstract: A gastrointestinal-tract constricting method includes, while observing the gastrointestinal tract by inserting an endoscope into the gastrointestinal tract, forming a spreading block that blocks infiltration of a substance, which damages a mucosa basal layer of the gastrointestinal tract, into the muscular layer underlying the mucosa basal layer, the spreading block being formed along a circumferential direction of the gastrointestinal tract and between the mucosa basal layer and the muscular layer; and supplying the substance along the circumferential direction of the gastrointestinal tract and to a surface of the mucosa that lies within a region that overlaps an inner side of the gastrointestinal tract with respect to the spreading block out of the entire circumference of the gastrointestinal tract in a transverse section of the gastrointestinal tract.

Abstract: A suture-fixing system includes an endoscope, a sheath, a suture-fixing tool, a lead-in tool, an engaging portion, a suturing instrument, and an operating portion. The engaging portion is capable of forming an encircled area extended in a loop shape or a U-shape. The encircled area can pass through the suturing instrument. The suturing instrument is capable of having the first delivery member and the second delivery member protrude from the endoscopic channel. The operating portion moves the first delivery member from a position in which the first delivery member and the second delivery are closed to a position passing through the encircled area while the first delivery member and the second delivery member protrude from the endoscopic channel and the encircled area portion protrudes from the distal end of the endoscope.

Abstract: A drug supply device includes: a tube body; a first expansion member configured to be expanded to a first outer diameter and a second expansion member configured to be expanded to a second outer diameter that is greater than the first outer diameter, the first expansion member and the second expansion member being positioned on a distal-end side of the tube body; and a masking member that extends between the expansion members and that is connected to outer surfaces of the expansion members at two ends thereof. The tube body includes an outlet that opens between the expansion members and a channel that is in communication with the outlet, the masking member is formed in an arc shape in a lateral cross-section that is orthogonal to the longitudinal axis, and the masking member stretches between the expansion members in a state in which the expansion members are expanded.
