ENDOVASCULAR GRAFT INCLUDING SUBSTRUCTURE FOR POSITIONING AND SEALING WITHIN VASCULATURE

摘要

An endovascular graft having an improved positioning mechanism capable of positioning and securing a bifurcated graft into a bifurcated vessel described. The graft can include a sleeve affixed to graft that is used in combination with a contralateral wire loop for placement of the graft within vasculature. The graft may include a structure for post deployment positioning into the bifurcated aneurysm area. Furthermore, the endovascular graft may be configured to form a sealing pocket that expands with induced fluid pressure and prevents fluid leaks at an attachment site.
