Abstract
A non-polymeric or biological coating applied to a radially expandable interventional medical device in a collapsed, wrapped, or folded configuration, the coating applied within at least one fold. Properties of the coating material applied to the medical device are adjusted or varied to result in a desired combination of coverage of the surface of the medical device, drug loading, and coating thickness. The coating is sterile, and is capable of being carried by a sterile medical device to a targeted tissue location within the body following radial expansion. The therapeutic coating transfers off the medical device due in part to a biological attraction with the tissue and in part to a physical transference from the medical device to the targeted tissue location in contact with the medical device.
