Abstract
A method of modifying the surface of a medical device to release a drug in a controlled way by providing a barrier layer on the surface of one or more drug coatings. The barrier layer consists of modified drug material converted to a barrier layer by irradiation by an accelerated neutral beam derived from an accelerated gas cluster ion beam. Also medical devices formed thereby.
