Abstract
Disclosed herein are medical devices, such as implantable medical devices (e.g., stents), comprising at least one coating covering at least a portion of the device comprising dry film. The dry film comprises at least one lipid bilayer and at least one pharmaceutically effective agent. Upon exposure to an aqueous fluid, liposomes are released comprising lipids from the dry film encapsulating the pharmaceutically effective agent. The film can contact the device directly or can be coated on a substrate, such as a ceramic.
