Patent number: 10806562Abstract: A low-profile stent graft has a Type-III endoleak suppression effect, avoiding the problem with a stent graft which uses an extra-thin graft incurring enlarged needle holes or needle hole parts in a suture part. The stent graft has a proximate end, a distal end, and a lumen which is positioned between the proximate end and the distal end. The stent graft is formed by coupling a cylindrical graft to a stent with a suture. The cylindrical graft is formed from a fabric having a thickness of 10-90 ?m. The elastic modulus of the suture is 40 cN/dtex or less.Type: GrantFiled: March 31, 2016Date of Patent: October 20, 2020Assignee: Asahi Kasei Kabushiki KaishaInventors: Tetsuko Takahashi, Junichi Kojima
