摘要

A delivery system serves for delivering a surgical stent craft (6). The delivery system comprises a delivery sheath (3) and a push shaft (4) and a core bar (7) with a core bar hole. The core bar (7) is provided with a bullet-like tip (9) at its head. The other end of the core bar (7) extends into the push shaft (4) and is connected fixedly with the push shaft (4). The push shaft (4) is provided inside with a through hole through which an external guide wire (8) can extend from the tip (9). (Fig. 7)
