Abstract
The present invention relates to stent structures having improved migration resistance. In particular, the invention relates to mesh stents, such as braided or twisted stent designs, where at least a portion of the stent is folded back over itself to form a multi-layered stent device. Such multi-layered portions provide for migration resistance, among other advantages.
