ABDOMINAL AORTIC ANEURISM (AAA) LOW PROFILE SUPPORT STRUCTURE

摘要

An endoprosthesis for repairing and treating abdominal aortic aneurysms. The
endoprosthesis features an anchoring and sealing component (100) and low
profile bifurcated legs (104, 106). A biocompatible graft material is secured
to at least the bifurcated legs in order to provide two endoleg fluid flow
lumens or conduits. The bifurcated legs have staggered stent elements (118)
that nest to contribute to the low profile nature of the device and additional
longitudinal struts (300) between pair of the staggered stent elements to
increase the longitudinal stiffness of the bifurcated legs while maintaining
the patency of the lumen created thereby.
