Abstract
Provided is a stent graft (1) comprising: a framework portion (B) having a ductal shape and which is expandable and contractable radially of the stent graft, and a membrane portion (GF) disposed along the framework portion. The membrane portion (GF) comprises a bent guide portion (RU) comprising a regular arrangement of textured structures formed radially of the stent graft. The bent guide portion is composed so as to have priority over other sections of the membrane portion in deforming when the stent graft bends.
