A stent-graft assembly is provided for a variety of medical treatments. The stent-graft assembly includes a stent disposed between an inner layer of graft material and an outer layer of graft material. The graft layers are effectively secured to the stent by attaching the graft layers together through openings in the structure of the stent. Relative movement between the graft layers and the stent is made possible by providing unattached margins between the attached areas of the graft layers and the edges of the stent openings. |
