Abstract:
1. An endovascular prosthesis comprising: a first stent, the first stent comprising a first end, a second end, and an inner surface defining an inner lumen; a first graft, the first graft comprising a first end, a second end, and an outer surface; a first membrane, the first membrane being non-planar with a first end having a first width sufficient to extend across an entirety of the inner lumen of the first stent; a second end having a second width less than the first width where only the first end is engaged to the inner surface of the stent, the second end comprising a first peak formation comprising an apex, the apex comprising a first graft receiving member configured to receive a graft, wherein the first membrane is non-planar with and without a graft positioned within the first graft receiving member, the first membrane being engaged between the first and second ends of the first stent; the first graft being positioned within the first graft receiving member, a first portion of the first peak formation conforming to a portion of the outer surface of the first graft, the apex of the first peak formation being closer to the first end of the first graft than the first portion of the first peak formation is to the first end of the first graft; wherein the first end of the first stent, the first end of the first graft, and the apex of the first peak formation are directed in a first direction; the second end of the first stent and the second end of the first graft are directed in a second direction opposite the first direction, the first end of the first graft being closer to the apex of the first peak formation than the second end of the first graft.
