Abstract
According to an aspect of the present invention, implantable or insertable medical devices are provided, which contain polymeric release regions that control the release of one or more therapeutic agents. The polymeric release regions, in turn, contain one or more polymers that contain one or more rigid, nonplanar polycyclic molecular structures. The therapeutic agent is disposed beneath or within the polymeric release region.
