Abstract

A stent graft comprises two stent segments connected to open ends of a graft, arranged along the length thereof without overlap, reducing the transverse size and facilitating deployment. It may include longitudinal struts, sliding stent, additional stent segments, removable stent(s), etc. Various methods are employed for deployment.Other stent graft deploying methods comprise independently introducing and maneuvering graft and stent segments to the repair site from one or more introduction sites, and assembling the stent graft at the repair site. Intravascular and/or extravascular deployment hardware may be employed. Additional sealing and/or structural stent segments may be deployed. Branched grafts may be deployed. Removable stent segment(s) may be employed for positioning the graft and then later removed.A stent anastomosis for securing/sealing a graft end is disclosed. A branched stent graft including two branch stent grafts deployed side-by-die within a main stent graft is disclosed.
