A stent assembly, comprising: a. a stent jacket, comprising an expansible mesh structure, having a retracted state and a deployed state, and further wherein in the deployed state, the expansible mesh structure defines apertures, and the expansible mesh structure is formed of fibers of a diameter between about 5 micrometers and about 25 micrometers, the diameter having a property of forming a substantially stable layer of endothelial cells, covering the fibers, thus reducing platelet aggregation； and b. an expansible stent, operatively associated with the stent jacket, the stent jacket being located on the exterior of the expansible stent.
