ENDOLUMINAL PROSTHESIS SYSTEM

摘要

An endoluminal prosthesis system may include a main graft and an extension graft. The main graft may include a tubular main body having a sidewall, open proximal and distal ends, a lumen, and a fenestration in the sidewall. The extension graft may include a tubular extension body, and tubular first and second extension legs. Each of the first and second extension legs may extend from the extension body and include a lumen in fluid communication with the extension body lumen. The extension graft may be deployable within the main graft such that the extension body extends through the fenestration in the sidewall of the main body. Each of the first and second extension legs may extend outward away from the main graft. An auxiliary guide such as an auxiliary cannula and/or auxiliary guide wire may be preloaded in the extension graft and extend through the lumen of each of the second extension leg and the extension body.

1. An endoluminal prosthesis system comprising:
a main graft comprising a tubular main body having an open proximal end, an open distal end, a sidewall, a lumen extending longitudinally between the proximal end and the distal end, and a fenestration in the sidewall between the proximal open end and the distal open end; and an extension graft comprising, a tubular extension body, a tubular first extension leg, and a tubular second extension leg, the extension body comprising an open first end, a second end, and a lumen extending longitudinally between the first end and the second end, each of the first extension leg and the second extension leg extending from the extension body and each comprising a first end, a second end, and a lumen in fluid communication with the lumen of the extension body; wherein the extension graft is deployable within the main graft such that the extension body extends through the fenestration in the sidewall of the main body and each of the first extension leg and the second extension leg extends outward away from the main graft.
