Abstract
A method of making a stent-graft is provided. The method includes mounting a stent on a mandrel so that the stent is stretched when it is on the mandrel. A graft layer is then adhered to the stent while it is mounted on the mandrel. When the stent-graft is removed from the mandrel, the stent contracts and the graft layer becomes partially wrinkled when the stent is in its expanded relaxed state.
