A drug-eluting stent (DES) is a type of stent that is placed in the body to help keep blood vessels open. It is coated with a medication that is slowly released over time to help prevent the formation of scar tissue, which can lead to a blockage of the vessel. The drug-eluting stent is most often used in the coronary arteries to help treat coronary artery disease (CAD). https://www.globalinsightservices.com/reports/drug-eluting-stent-market
