Abstract: A tissue collector includes: an elongated sheath; a bag; a wire bending portion; and an extending portion which is arranged at the distal end portion of the sheath so as to protrude forward from the distal end portion along the longitudinal axis and enter an inside of the bag. The extending portion intersects with the opening surface that is defined by an opening end of the opening portion. The extending portion is configured to be capable of extending inside the bag from an opening surface toward the bottom portion.

Abstract: A medical device includes a long shaft member, a curved portion configured to be curved, a support member that is configured to be deformed along a curved shape of the curved portion, a guide member that extends from a distal end of the curved portion, and a linear member that includes a connection portion connected to the guide member, the linear member being inserted into the support member, and that pulls the guide member in accordance with a change of the curved shape. A central axis of the guide member is positioned apart from the central axis of the support member. The linear member which protrudes from the support member is inclined with respect to a longitudinal axis of the guide member and is connected to the connection portion.

Abstract: An endoscopic treatment method includes: inserting an endoscope into a digestive tract; forming a damaged area in at least a portion of the digestive tract along a circumferential direction by performing cauterizing while keeping a mucosal layer by observing with the endoscope; and forming an incomplete stenosis in the digestive tract, while restoring the damaged area, wherein the damaged area is formed by causing damage to a mucosal base layer, the mucosal base layer having an interface that contacts a submucosal layer.

Abstract: A clip unit includes: an arm portion including arms extending from a proximal end portion to a distal end portion so as to be openable and closeable; a holder than can hold the arms in a closed state by accommodating the proximal end portion of the arm portion; and a thread grip attached to at least one of the arms and positioned between the arms. In a state where the arms are spread open, a dimension of the thread grip in the opening/closing direction of the arms is equal to or larger than a distance between the arms in the closed state. The thread can be elastically deformed in the closed state.
