Abstract: A treatment tool for an endoscope includes: a sheath; a balloon provided at a distal end of the sheath, and configured to be expandable from a folded initial shape to an unfolded inflated shape; an inner shaft configured to protrude from a distal end of the balloon through an inside of the balloon; a middle marker; and at least one or more positioning markers provided on the inner shaft independently of the middle marker. The balloon has a proximal end-side region, a distal end-side region, and a middle part. At least one of the positioning markers is positioned on the inner shaft at same a longitudinal position as the proximal end-side region.

Abstract: A treatment tool for an endoscope of the present invention includes a sheath, a balloon provided at the sheath and configured to be expandable to an inflated state from a reduced diameter state by injecting a fluid, a shaft member inserted through an inside of the balloon and configured to extend along a longitudinal axis of the sheath from a distal end of the balloon to a proximal end thereof, and an adhering portion provided on a side of an inner surface of a central portion of the balloon in a direction of the longitudinal axis, formed of an adhering material applied or adhered to the shaft member and configured to hold the central portion in a state in which the central portion is reduced in diameter.
