Researchers at the University of Catania, Italy, have announced the results of a 55 patient study of a new artery stent coated with inert nanoscale Polyzene (R)-F.  Preliminary results indicate almost complete healing after 30 days.  The antithrombotic surface is 40 nm thick and is bacterial resistant.  Scientists believe the nanocoating "hides" the stent from the body allowing it to incorporate into the body and heal faster. The new stent evidently offers substantial benefits over current drug-eluting stents in which clots have been known to form.  Source: azonano.
