摘要：A low profile, abdominal aortic aneurysm exclusion device with iliac vesselextensions. A sectional, bifurcated stent forms part of an endoluminal prosthesis toeliminate or reduce the risk of rupture of aortic aneurysms. An apparatus and a methodfor introducing the bifurcated stent in sections into the vasculature and assembling thesections in situ to form a “scaffold” for introduction of material to re-endothelializeand/or occlude the aneurysm cavity. After trans-stent embolization of the aneurysmcavity with thrombogenic material, laminar flow stimulates endothelialization of the stentlumen. Subsequent organization and fibrosis of the persistent thrombus reinforces thewire-mesh or etched metal tubular scaffold comprising the stent and serves to stabilizeand shrink the aneurysm. A single stent deployed with the same method may be used innon-bifurcated vessels.
