    摘要： An implant comprises an elongate member, and anchors distributed along the elongate member. A gripper comprises a locking element that, in a locked state thereof, inhibits sliding of the elongate member through the gripper by clamping the elongate member. A tool is configured to, while (i) the elongate member extends proximally from a proximal-most of the anchors, and through the gripper, and (ii) an unlocker is positioned within the gripper in a manner that obstructs the locking element from assuming the locked state: (A) advance transluminally toward the proximal-most anchor, and (B) tension the elongate member by pulling the elongate member proximally through the gripper while the unlocker obstructs the locking element from assuming the locked state. The tool is also configured to subsequently facilitate the locking element clamping the elongate member via withdrawal of the unlocker from the gripper. Other embodiments are also described.

    摘要： The invention relates to an implant for arranging and expanding in the human gastrointestinal tract for the purpose of lining a section of the gastrointestinal tract in order to prevent the resorption of supplied nourishment in said section, having a first end section (1) which, as a securing section, allows the fixation of the implant in the human stomach/gastrointestinal tract and/or to an applicator (10); a tubular section which adjoins the first end section (1), comprising a longitudinal section (2) which extends in the provided expansion direction, a transition section (3) which adjoins the longitudinal section (2), and an inverted section (4) which runs within the longitudinal section opposite the provided expansion direction; and a second end section (8). According to the invention, a region of the inverted section (4) and a region of the longitudinal section delimit a flow channel (5), via which a fluid (15) blown into the tubular section can penetrate the transition section (3) in order to exert pressure thereon, wherein the inverted section (4) radially delimits a cavity (6) and has a closure section (7) which forms the second end section (8) and axially delimits the cavity (6).

    摘要： This covered stent 100, which is released from a sheath 200 and placed in a lumen in a living body, is provided with: a tubular skeleton portion 11 which is stretchable in the axial direction and is expandable in the radial direction substantially perpendicular to the axial direction; and a stretch restriction portion 2 for restricting stretching of the skeleton portion in the axial direction. The stretch restriction portion is formed from a material different from that of the skeleton portion and restricts stretching of the skeleton portion in the axial direction when the skeleton portion is contracted in the radial direction while being stored in the sheath.
