Abstract
(EN) Provided are a stent (1), a stent kit and a stent delivery system (100). The stent (1), for use in the aorta, is characterized in that the stent is at least made of a first wire (3) and a second wire (4) of different diameters by means of weaving, and the stent (1) is configured to be at least partially compressible and extensible in the axial direction of the stent (1) in a natural release state, wherein the first wire (3) has a diameter of 20-150 μm, and the second wire (2) has a diameter of 150-800 μm. When the stent (1) is used in the treatment of aortic aneurysm lesions and/or aortic dissection lesions, the stent (1) provides low fluid permeability and a strong radial support force at the desired site in the aorta by means of the axial compressibility and extensibility of the stent, and is easily assembled into the delivery system (100) having a suitable diameter by means of the axial extensibility of the stent. Further provided are the stent kit comprising the stent (1), and the stent delivery system (100).
(FR) L'invention concerne une endoprothèse (1), un kit pour endoprothèse et un système de pose d'endoprothèse (100). L'endoprothèse (1), destinée à être utilisée dans l'aorte, est caractérisée en ce qu'elle est au moins constituée d'un premier fil (3) et d'un second fil (4) de diamètres différents au moyen d'un tissage, et l'endoprothèse (1) est conçue pour être au moins partiellement compressible et extensible dans la direction axiale de l'endoprothèse (1) dans un état de libération naturelle, le premier fil (3) présentant un diamètre de 20 à 150 µm, et le second fil (2) présentant un diamètre de 150 à 800 µm. Lorsque l'endoprothèse (1) est utilisée dans le traitement de lésions d'anévrisme aortique et/ou de lésions de dissection aortique, l'endoprothèse (1) assure une faible perméabilité aux fluides et une forte force de support radiale au niveau du site souhaité dans l'aorte au moyen de la compressibilité et de l'extensibilité axiales de l'endoprothèse, et est facilement assemblée dans le système de pose (100) présentant un diamètre approprié au moyen de l'extensibilité axiale de l'endoprothèse. L'invention concerne en outre le kit pour endoprothèse comprenant l'endoprothèse (1), et le système de pose d'endoprothèse (100).
(ZH) 一种支架(1)、支架套件及支架递送系统(100)。支架(1)用于主动脉中,其特征在于,支架由至少两种不同直径的第一丝(3)和第二丝(4)编织而成,支架(1)构造为在自然释放状态下沿支架(1)的轴向是至少局部可压缩的且可延伸的,其中第一丝(3)具有20~150μm的直径,且第二丝(2)具有150~800μm的直径。支架(1)在用于治疗主动脉瘤和/或主动脉夹层病变通过支架(1)的轴向可压缩和延伸性,在主动脉中有需要的部位提供低透液性和强径向支撑力,以及通过其轴向的可伸展性,容易地组装至具有合适直径的递送系统(100)中。还提供包括支架(1)的支架套件及支架递送系统(100)。
