Abstract

Devices, systems, and methods are employed to perform an atherectomy in an identified region to restore patency to arterial lesions. A bioactive material is introduced into the identified region before, after or during performing the atherectomy. The bioactive material can be introduced, e.g., on a balloon coated with the bioactive material, which is expanded in contact with the identified region to deliver the bioactive material. The bioactive material can be, e.g., at least one of a restenosis-inhibiting agent, a thrombus-inhibiting agent, and an anti-inflammatory agent.
