Abstract
A thin-walled prosthesis is provided that includes a tubular graft formed of a monofilament fiber. The graft has sufficient strength and durability to withstand loads applied during deployment and while implanted and sufficiently low permeability to prevent excessive leakage of body fluids through the material or to provide a sufficient seal, for example, so as to prevent aneurysm pressurization. A preferred embodiment of the present invention relates to a tubular grafts constructed of monofilament fibers for endoluminal placement within a body lumens, including blood vessels, and for the treatment of abdominal and other aneurysms.
