Abstract
A method for fabricating a coating for an implantable medical device is provided comprising applying a first polymer on at least a portion of the device to form a first layer of the coating and applying a second polymer on at least a portion of the first layer to form a second layer of the coating. The second polymer has a lower degree of hydration than the first polymer.
