Abstract:
The present invention relates compositions for delivering therapeutic agents from a medical device including an expandable and collapsible structure and methods employing them. A lipid coating including one or more fatty acids increases the amount of therapeutic agent released from the device at the delivery site. The therapeutic agent can be in a matrix including a hydrophilic polymer or an amphiphilic polymer. Release and adhesion coatings can also facilitate delivery of therapeutic agent.
