The world market for medical device coatings could exceed $7.5bn by the year 2015, according to a new report by US firm Global Industry Analysts.

The growth would be triggered mainly by a rapid increase in the incidence of hospital-acquired infections (HIAs)caused by bacterial contamination of medical devices, and other factors including emphasis on reduced hospital stays, increasing awareness of benefits of coated medical devices, and an increase in joint replacement surgeries.

Coatings for medical devices are thin layers of materials applied on medical devices to enhance their safety and performance, by helping reduce friction between devices and tissues and providing surface coverage, wetting, uniform adhesion, wear-resistance and coating homogeneity.

North America is the world leader in this market where HAIs are becoming a major healthcare issue, promoting the use of catheters with antimicrobial coatings, according to the Coatings for Medical Devices: A Global Strategic Business report.

Another factor for the market’s growth is drug-eluting stents, which have been proven to reduce the recurring revascularisation procedures required for treating restenosis.
