STENT GRAFT FIXATION COUPLING

摘要

A small vessel stent graft (30; 62) with a fixation coupling (10; 50) that has a hyperboloid shape positioned at or near the proximal end of the graft (30; 62). The coupling (10; 50) may be deployed within the fenestration (42; 65) of a fenestrated graft (40; 60) to provide multi-directional movement without compromising the integrity of the sealing zone.
