| Zusammenfassung: | A treatment system includes a guide sheath provided with a pre-curved portion that has been preliminarily curved in a direction intersecting a longitudinal axis at a distal end of a tubular sheath body having the longitudinal axis, and an overtube forming a first lumen through which the guide sheath is passed and a second lumen through which an endoscope is passed, in which a cross-sectional shape of an inner peripheral surface defining the first lumen has a shape configured to house the guide sheath in a state where the pre-curved portion remains curved. |
