Abstract

A barrier layer and corresponding method of making provide anti-inflammatory, non-inflammatory, and anti-adhesion functionality for a medical device implantable in a patient. The barrier layer can be combined with a medical device structure to provide anti-adhesion characteristics, in addition to improved healing, non-inflammatory, and anti-inflammatory response. The barrier layer is generally formed of a naturally occurring oil, or an oil composition formed in part of a naturally occurring oil, that is at least partially cured forming a cross-linked gel. In addition, the oil composition can include a therapeutic agent component, such as a drug or other bioactive agent.
