Abstract:
1. A method for producing a self expanding stent-graft device that comprises providing a stent having a fully compacted diameter, a fully expanded diameter, and an intermediate diameter between the fully compacted diameter and the fully expanded diameter; orienting the stent at its fully expanded diameter; forming an elastomeric cover on the stent to form the stent-graft; orienting the stent at its intermediate diameter at a temperature less than the temperature that would induce the stent to self-expand; and re-flowing the elastomeric cover at a temperature less than the temperature that would induce the stent to self-expand to be substantially wrinkle-free at such intermediate diameter, wherein the stent-graft is substantially wrinkle-free when self expanding from the intermediate diameter to the fully expanded diameter of the stent.
