Abstract
A stent based drug delivery system. A biological agent of interest is entrapped within a matrix, which is loaded into channels on the surface of a stent. The matrix allows for release, usually sustained release, of the entrapped agent. The stent and matrix is sheathed with a covalently bound gel. In one embodiment of the invention, the stent is used to deliver therapeutic agents to a patient, providing the advantage of efficient delivery and sustained release of an agent at a localized site. In another embodiment of the invention, the drug delivery system is used for testing and comparison of candidate drugs in an in vivo setting.
