Modular stent graft assembly and use thereof

The modular type stent graft assembly object 10 of the present invention has the tubular graft 12 of the portion for main arteries, and the tubular graft 14 of the portion for ilia, and treats the abdominal aneurysm 90 which exploded. A main artery tubular graft has the attachment stent 30 for the origins on it, in order to attach a stent graft assembly object to a main artery from a kidney. The Nemoto portion 50 of the ilium partial graft 14 enters under the tip part 28 of the main artery stent graft 12, and it forms conformity by friction, applying compressive force towards the outside in the elastic domain 64 from there. The assembly object 10 of this 願発明 has the distribution system 100 of the graft 12 of the portion for main arteries of the size of four pieces, the distribution system 200 of the four partial grafts 14 for ilia, and the distribution system 250 containing the occlusion machine 80 of standard size, and can suit the size of many aneurysms now.
