摘要： A luminal stent (100) is provided, including a tubular main body (11) and a semi-releasing device (20) connected to the tubular main body (11). The tubular main body (11) includes a binding area (112) and a non-binding area (111) distributed in a circumferential direction. The semi-releasing device (20) includes a limiting rod (21) located outside the tubular main body (11), and binding lines (22) and limiting fasteners (23) arranged on the tubular main body (11). The binding lines (22) are arranged in the binding area (112). The binding lines (22) each include a fixed end (22a), a binding portion (22b) and a locking portion (22c) which are connected to one another. The fixed ends (22a) are fixedly connected to the tubular main body (11). Both the locking portions (22c) and the limiting fasteners (23) are detachably connected to the limiting rod (21). When both the locking portions (22c) and the limiting fasteners (23) are connected to the limiting rod (21), the binding lines (22) circumferentially constrain the binding area (112). By uniformly compressing a part of a circumferential area of the luminal stent (100), the luminal stent (100) can be in a semi-released state, thereby adjusting and positioning the luminal stent (100), and improving the accuracy of the axial and circumferential positioning of the luminal stent (100).

摘要： A lumen stent (100) includes a tubular stent and an imaging marker; the tubular stent includes a main body stent (11); the imaging marker includes a first marker (211) provided on the main body stent (11); and the shape of the first marker (211) provided on the main body stent (11) is asymmetrical at least along a longitudinal axis. A non-axisymmetric imaging marker is provided on the main body stent (11), and the position and orientation of the lumen stent (100) implanted in the body can be accurately and clearly displayed through the imaging marker, to allow the operator to observe and quickly judge and timely adjust, thereby shortening the operation time of the endovascular treatment and reducing the difficulty of the operation.

摘要： A lumen stent (100) and an implant are provided. The lumen stent includes a tubular body (11), an inner branch (12) and an outer branch (13) which are respectively communicated with the tubular body (11). The tubular body (11) includes a first body segment (111), a tapered segment (112) and a second body segment (113) which are connected in sequence. The tapered segment (112) is provided with an outer branch window (110b) and an inner branch window (110a). The proximal end of the outer branch (13) is connected to the outer branch window (1 10b). The distal end of the inner branch (12) is connected to the inner branch window (110a). The area of the inner branch window (110a) is larger than that of the outer branch window (1 10b). The beneficial effects are as follows: since the area of the inner branch window (1 10a) is larger than that of the outer branch window (1 10b), most of blood flow can rapidly pass through the inner branch (12), so that the blood flow pressure of the outer branch (13) is reduced, and the distal end of the outer branch (13) is prevented from tilting and touching an inner wall of a tumor cavity.
