Abstract
An implantable medical device, such as a stent, is disclosed. The device includes a substrate and a polymeric layer including poly(methylmethacrylate) or poly(butylmethacrylate) supported by the substrate. The polymeric layer contains rapamycin. A barrier is over at least a portion of the polymeric layer to reduce the rate of release of rapamycin from the implantable medical device. The polymeric layer can additionally include poly(ethylene co-vinyl acetate).
