ABSTRACT:
In one embodiment of the present invention a coating topology, or engineered surface architecture that may be referred to as a microdroplet deposited engineered surface architecture is provided. A plurality of drops are placed on the stent with the purpose, of building up individual units of coating material on the outer stent surface. This architecture results in a coating that uses less material, i.e., polymer, solvent, medicine, while at the same time providing for better, and determinable, drug kinetics, approaching 100% delivery and better mechanical operation of the coating binding to the stent.
