ABSTRACT:
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.
