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.

1-11. (canceled)
An implantable medical device comprising:
- a first section and a second section, wherein the first section has higher strain than the second section when the device is placed under an applied stress during use;
- and
- a nonuniform coating on the device, wherein a strain on the nonuniform coating is less than a strain on a uniform coating when the device is placed under the applied stress during use.
13-24. (canceled)
A method of selectively coating an implantable medical device comprising:
- forming a nonuniform coating on an implantable medical device comprising a first section having higher strain than a second section when the device is placed under an applied stress during use, wherein a strain on the nonuniform coating is less than a strain on a uniform coating when the device is placed under the applied stress during use.
