SurModics doesn't want to scratch the surface of the medical device market -- it just wants to coat it with its own special agent. The company's medical device unit makes special coatings that make the devices easier to use, less traumatic to the body, and even useful in delivering drugs to patients. The company's Bravo polymer coating is used on Cordis' drug-coated coronary stent (among other products) and delivers drugs that prevent re-narrowing of the artery. SurModics' in vitro diagnostics (IVD) unit handles diagnostic test and research kits and products. Three scientists formed the company in 1979.
