Programmable elution profile coating for drug-eluting stents.(materials)

Despite good results in reducing in-stent restenosis during cardiac stenting procedures, a number of issues in the application of drug-eluting stents still challenge the industry. These include drug-elution kinetics and long-term biocompatibility. Some of the latest developments in these areas are described here.

Building on current progress

Coronary-stent implantation, that is, percutaneous transluminal coronary angioplasty has been proven to be superior to conventional balloon angioplasty for the treatment of diseased coronary arteries. However, the major
