The invention discloses a stent retractor/distractor which includes a radially flexibly enlargeable, pipe-shaped sheath which is divided up in the circumferential direction in at least two sections, namely one stiffening section and one enlarging section with differing radial flexibilities, which are connected with each other in one piece of material. The stent retractor/distractor defined in that way is made on the whole by a laser or water jet cutting procedure, preferably from a pipe blank. 本发明公开种支架牵开器/撑开器，其具有径向柔性可扩大的、管道形护套，所述护套在圆周方向上分成至少两个区段，即具有不同径向柔韧性的个加强区段和个扩大区段，所述加强区段和所述扩大区段彼此连接成件材料。以那种方式定义的所述支架牵开器/撑开器总体上借助于激光或水射流切割程序、优选地由管道坯料制成。
