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.

Selective coating of an implantable medical device

The emboli protection system provides one or more inflatable blocking balloons for isolation of a section of a blood vessel to prevent migration of emboli from the section during an interventional procedure, and fluid infusion and evacuation ports for flushing emboli from the isolated section. One embodiment provides for a distal blocking balloon catheter, over which an interventional device can be introduced, and a proximal blocking balloon catheter to be introduced over the interventional device for isolating a portion of a blood vessel to be treated. The blocking balloons can be perforated to provide the infusion ports, and thrombolytic inflation fluid may be used to break down and dissolve thrombus and plaque in the isolated portion of the blood vessel. The interventional therapeutic device such as an angioplasty balloon catheter may be incorporated into the distal blocking balloon catheter, or the distal and blocking proximal balloon catheters can be incorporated with the interventional therapeutic device together in one device. Infusion ports may also be provided in either or both of the distal and proximal blocking catheters.
