    • A delivery catheter having an inner catheter assembly, an inferior capsule catheter, and a capsule jacket assembly for use in deploying a graft having a compressible and expandable attachment systems in the thoracic region of an aorta. The graft is comprised of a tubular member having superior and inferior ends, each having an attachment system with wall engaging members secured thereto and is crimped along its midsection to resist kinking and elongation. The delivery catheter includes an inferior capsule assembly for releasably retaining the inferior attachment system of the graft and a superior capsule assembly for releasably retaining the superior attachment system of the graft as well as a releasing system for maintaining the attachment systems in a compressed configuration and for facilitating expansion of the attachment systems. The delivery catheter also includes an anti-elongation wire attached to the inner catheter assembly to prevent stretching of the delivery catheter during deployment of the graft within the aorta. Upon removing the attachment systems from the capsule, the releasing system functions to allow the attachment systems to assume their expanded configuration and engage the walls of the aorta. The graft and attachment systems remain in the vessel after the delivery catheter is withdrawn.
    • 具有内导管组件,下胶囊导管和胶囊护套组件的输送导管,其用于部署具有在主动脉的胸部区域中的可压缩和可扩张的附接系统的移植物。 移植物由具有上端和下端的管状构件组成,每个管状构件具有固定到其上的壁接合构件的附接系统,并沿其中部卷曲以抵抗扭结和伸长。 递送导管包括用于可释放地保持移植物的下部附接系统的下部胶囊组件和用于可释放地保持移植物的上部附接系统的上部胶囊组件以及用于将附着系统保持在压缩构型中的释放系统,并且 促进附件系统的扩展。 递送导管还包括附接到内导管组件的抗延伸丝,以防止在将主动脉内的移植物展开期间伸出导管。 在从胶囊中取出附接系统时,释放系统的作用是允许附接系统呈现它们的扩张构型并且接合主动脉的壁。 输送导管拔出后,移植物和附着系统保留在血管内。
