    摘要： A non-polymeric or biological coating applied to radially expandable interventional medical devices provides uniform drug distribution and permeation of the coating and any therapeutic agents mixed therewith into a targeted treatment area within the body. 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. Thus, atraumatic local tissue transference delivery is achieved for uniform therapeutic agent distribution and controlled bio-absorption into the tissue after placement within a patient's body with a non-inflammatory coating.

    摘要： A non-polymeric or biological coating applied to radially expandable medical delivery device provides uniform drug distribution and permeation of the coating and any therapeutic agents mixed therewith into a targeted treatment area within the body. The delivery device is expanded using the pressure of an inflation fluid. After expanding the delivery device to a pre-determined size and shape, the inflation fluid weeps through the porous surface of the delivery device. The coating releases the delivery device and floats on the inflation fluid until bonding to the tissue due to its affinity for the tissue. Once the coating bonds or affixes to the tissue, through an absorption mechanism by the tissue cells of the coating material, the coating and any therapeutics contained therein are delivered to the tissue. The fluid can contain a therapeutic agent, or can be otherwise biocompatible and/or inert.
