Abstract: A gastrointestinal-tract constricting method comprises: while observing the gastrointestinal tract with an endoscope inserted into the gastrointestinal tract, placing a protection substance, which does not damage tissue, in at least one of a region between the mucosal layer and muscular layer of the gastrointestinal tract and a region in a mucosal surface of the mucosal layer so as to form a protection region that protects the mucosa basal layer from a medical substance that damages the tissue; and, after forming the protection region, supplying the medical substance to a mucosal surface in a target region, which is at a position different from the protection region in a circumferential direction of the gastrointestinal tract, or to a position between the mucosal layer and the muscular layer.

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 suppresses 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 to a gap between the spreading block and the mucosa basal layer while forming a contact surface between the spreading block and the substance along the circumferential direction of the gastrointestinal tract.

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.

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 gastrointestinal tract constricting method according to the present invention aims to constrict the gastrointestinal tract by contracting a desired region of the gastrointestinal tract by a simple and low-invasive procedure. The method includes forming spreading blocks while observing the gastrointestinal tract with an endoscope inserted into the gastrointestinal tract, the spreading blocks being formed at a position between a mucosa layer and a muscle layer and on both sides of a target region, which is to be damaged by a substance, in a circumferential direction of the gastrointestinal tract so that the spreading blocks block spreading of the substance in the circumferential direction of the gastrointestinal tract to prevent spreading of the substance to an outer side of the target region, and supplying the substance to a mucosal surface of the target region or to the position between the mucosa layer and the muscle layer after formation of the spreading blocks.
