Researchers investigate differences in coatings of drug-coated balloon catheters

Drug-coated balloon catheters to open narrowed blood vessels and to deliver drugs to the impacted sites are used frequently for the treatment of peripheral arterial disease. Scientists believe improvement of the coatings could lead to better designs and improved outcomes. Now for the first time, researchers at Boston University School of Medicine (BUSM) have examined these coatings at microscopic levels in hopes of producing more efficient alternatives for treating arterial disease.
