摘要:
The present embodiments provide stent-grafts. In one embodiment, a stent has proximal and distal ends, a plurality of strut segments disposed between the proximal and distal ends that enable expansion of the stent from a compressed state to a deployed state, and a series of distal apices disposed at the distal end of the stent. At least a portion of a first distal apex overlaps with graft material. First and second sutures are each coupled between a portion of the first distal apex and the graft material. The first and second sutures are positioned at different longitudinal zones that lack an axial overlap with one another.
