    摘要： An apparatus and method related to a drug eluting stent with improved adhesion between a drug excipient coating and a stent substrate is described. In one embodiment of the present invention, an apparatus comprises a stent substrate formed of a metal and/or a polymer and having a surface modified by exposure to ultraviolet light and an atomic oxygen molecule. A polymeric material is coupled with the surface of the stent substrate. In another embodiment, a method includes providing a stent with an adhesive property that is associated with the surface of the stent. The adhesive property of the stent is modified by exposing the surface to ultraviolet light and an atomic oxygen molecule.
