A stent (or stent graft) locating device 10 comprises a number of leading wires 1, a pushing rod 6 for holding the number of leading wires in its circumferential direction and a sheath 7 for loading the pushing rod 6. The pushing rod is composed of an inner tube 6A and an outer tube 6B, a hollow portion of said inner tube is used as a guiding wire channel and another sectional ring-shaped hollow portion between said inner tube and said outer tube is used as a leading wire channel 6D. The pushing rod may be constructed of a single tube , a hollow portion of said tube is used as a guiding wire channel 6b, 6C and a plurality of leading wire channels 6c are arranged in a body of said tube at approximate regular intervals in its circumferential direction. The pushing rod 6 may have a plurality of leading wires 1 which are scattered at approximate regular intervals in the circumferential direction, a plurality of crossing leading wires 2 which are scattered in the circumferential direction, or a plurality of leading wires 1 and a plurality of auxiliary leading wires 3 which are scattered at approximate regular intervals in the circumferential direction. These wires are derived from the tip of a leading wire channel(s) 6D, 6c. The pushing rod may have plural lead-in wires 5 which are derived from the tip of the leading wire channel and engaged with the knees 11a at the terminal of the stent at approximate regular intervals by detachable engaging means (5a, 5b). <IMAGE> |
