Coating a stent may include continuously rotating the stent in one direction while spraying a first coating layer followed by continuously rotating the stent in another direction while spraying a second coating layer, wherein the first layer is preferentially distributed over a side surface of the stent struts and the second layer is preferentially distributed over an opposite side surface of the stent struts. The overall coating distribution combining both layers may be evenly distributed over the two side surfaces of the stent struts.
