Abstract: Acceleration of the endothelialization process on implantable medical devices having at least one blood-contacting surface is achieved by a microscale pattern of sub-sections of EC-inductive coatings or EC-conductive coatings and nano/macro textured surfaces. The EC-inductive coating and EC-conductive coating can be applied either on the entire surface of the blood-contacting surface or selective placed on the blood-contacting surface, for example, in particular patterns. In this regard, the EC-conductive and EC-inductive coatings can be selectively placed relative to the textured surface to achieve a desired pattern of texture surface to coatings.
