Abstract:
A coating and a method of coating an implantable medical device, such as a stent, is disclosed. The coating compensates for regions of higher stress and resulting strain due to the geometry of the device. Certain embodiments may include a nonuniform coating on the device in which a strain on the nonuniform coating is less than a strain on a uniform coating when the device is placed under an applied stress during use. Other embodiments may include a coating with a greater resistance to strain on higher strain regions of the device.
