The EU approved the first drug-coated balloon for treatment of in-stent restenosis nearly a decade ago, but U.S. physicians continue to have their hands tied in treating the fairly common problem. Results from Boston Scientific Corp.’s investigational device exemption trial for its Agent paclitaxel-coated balloon presented in San Francisco at Transcatheter Cardiovascular Therapeutics could finally put the tool in the hands of cardiologists. The device demonstrated a nearly 50% reduction in the risk of target lesion revascularization and target vessel myocardial infarction compared to conventional balloon angioplasty.
