    • A stent delivery and deployment system for use primarily with self-expanding stents, incorporating a traction tube extending over the length of the diametrically compacted and constrained stent and everting back over itself, with the outer everted portion of the traction tube preferably extending to the proximal end of the delivery system. A constraining sleeve is provided between the inner, non-everted portion and outer, everted portion of the traction tube, the constraining sheath extending over the length of the constrained stent prior to deployment and diametrically constraining the diametrically compacted self-expanding stent. The application of tension to the proximal end of the traction tube causes the constraining sheath to move in a proximal direction, freeing the constrained stent as it moves and allowing the stent to deploy against the wall of the body conduit within which it is located during the deployment process.
    • 主要用于自扩张支架的支架输送和展开系统,其包括在直径紧凑且受约束的支架的长度上延伸的牵引管,并且其牵引管的外转部优选地延伸到近端 送货系统结束。 约束套筒设置在牵引管的内部未弯曲部分和外部弯曲部分之间,约束护套在展开之前在约束支架的长度上延伸并且直径约束径向压实的自扩张支架。 向牵引管的近端施加张力导致约束护套在近端方向上移动,当被约束的支架移动时释放被约束的支架,并允许支架在其中位于其内的身体导管的壁部分 部署过程。
