The present invention is related to a low profile endolumenal prosthesis. The prosthesis comprises a radially expandable tubular wire support and an expanded PTFE membrane. The density, wall thickness and intranodal distance of the ePTFE are selected to inhibit the formation and nourishment of a viable neointima on the inner surface of the prosthesis, through the ePTFE membrane.

Endolumenal vascular prosthesis with neointima inhibiting polymeric sleeve

Disclosed is a tubular endoluminal vascular prosthesis, useful in treating, for example, an abdominal aortic aneurysm. The prosthesis comprises a self-expandable wire support structure having a tubular main body support and first and second branch supports. The support structure may include sliding links to permit flexibility while maintaining patency of the central lumen. The branch supports may articulate with the main body to permit the branches to pivot laterally from the axis of the main body throughout a substantial range of motion. Exoskeleton components or barbs may be provided to resist migration and endoleaks.
