A stent graft device for providing flow diversion through a body lumen, the body lumen having a luminal wall defining a luminal interior, the stent graft comprising:
- a substantially tubular stent structure;
- a substantially tubular, porous mesh structure coaxially disposed over and affixed to at least a portion of the stent structure;
- and
- substantially tubular graft material disposed over and affixed to at least a portion of the stent structure and a portion of the mesh structure, the graft material and the mesh structure being oriented such that an end portion of the mesh structure extends past an end portion of the adjacent graft material, the stent structure and the graft material being configured to create a first seal between the stent graft device and the luminal wall of the body lumen, the substantially tubular stent structure and the mesh structure being configured to create a second seal between the stent graft device and the luminal wall.
