MODULAR STENT GRAFT EMPLOYING BIFURCATED GRAFT AND LEG LOCKING STENT ELEMENTS

摘要

A modular stent graft system and associated surgical methods are provided that incorporates an external stent-based locking mechanism to prevent disarticulation of the legs from the bifurcated graft as well as other features that overcome many of the difficulties of the prior art associated with delivering and securing the bifurcated grafts to the intended deployment site within the human aorta.
