Abstract
A stent is differentially coated to accommodate areas of high strain. A therapeutic coating is applied to only those areas of the stent that do not experience high strain. This allows a therapeutic coating to be chosen for its elution characteristics, for example, rather than for its ability to withstand high strain. An elastic coating may be applied to the areas of high strain. The elastic coating may or may not include a therapeutic agent.
