Abstract: The present invention relates to a vascular stent that includes an expandable stent defining an interior compartment, a first polymeric layer exposed to the interior compartment defined by the stent, the first layer comprising an agent that promotes re-endothelialization, an agent that inhibits thrombosis, or a combination thereof, and a second polymeric layer at least partially external of the stent, the second layer being adapted for contacting a vascular surface and being characterized by pores that are substantially impermeable to vascular smooth muscle cell migration. Method of making and using the vascular stent are also disclosed.

Abstract: A respirable one-ply, two-ply or multi-ply barrier fabric including one web comprising an electrostatically charged melt blown fibers nonwoven or a nanofiber/melt blown fibers nonwoven having a weak cationic emulsifier to reduce surface energy of the fibers so as to minimize penetration and wetting by oily mists and to thereby preserve the effectiveness of electrostatic charges applied to fibers. Also disclosed is a two-layer or multi-ply barrier fabric which has at least one barrier fabric layer which is impermeable to liquids such as water and body fluids, but which allows the transport of moisture vapor through the micropores or by chemical absorption of water through a monolithic membrane, which may have additional barrier layers to include melt blown and nanofiber/melt blown composites.
