    • The application provides a system that distributes along the length of a stent those forces exerted on the stent during release of the stent from a sheath. The system includes a catheter inner member (110), a stent (120) , and a sheath (130). Multiple longitudinally spaced protrusions (115a, b, c) extend from the outer surface of a distal portion of the inner member. Complementary longitudinally spaced apertures (125a, b, c) are formed in the wall of the stent. The stent is mounted on the inner member with the inner member protrusions received within the stent apertures. The sheath encloses the stent and is movable with respect to the stent. The system is assembled by aligning the protrusions and apertures and radially compressing the stent about the inner member. The resulting interlocked protrusions and apertures allow the stent to be withdrawn from a radial compression device into the sheath by pulling on the inner member.
    • 该应用提供了一种系统,其沿着支架的长度分布在支架从护套释放期间施加在支架上的力。 该系统包括导管内部构件(110),支架(120)和护套(130)。 多个纵向间隔的突起(115a,b,c)从内部构件的远端部分的外表面延伸。 互补的纵向间隔的孔(125a,b,c)形成在支架的壁中。 支架安装在内部构件上,内部构件突起容纳在支架孔内。 护套包围支架并且可相对于支架移动。 通过对齐突起和孔并且围绕内部构件径向压缩支架来组装系统。 所产生的互锁的突起和孔允许通过拉动内部构件将支架从径向压缩装置拉出到护套中。
