Polymer coating techniques for drug-eluting stents.

As the use of coronary stents continues to expand worldwide, in-stent restenosis remains a major clinical problem for interventional cardiologists. However, recent clinical trials have shown that the drug-eluting stents are the most promising method for reducing the restenosis and allowing the injured vessel to heal. Further development work is focused on investigating the use of this technology with a range of drugs for the inhibition of restenosis.
