1. A system for coating an implantable medical device with a coating composition, comprising:
a reservoir holding a coating composition;
an applicator including a coating surface and a porous region in fluid communication with the coating composition in the reservoir, wherein the porous region is capable of conveying the coating composition from the reservoir to the coating surface, the applicator further including:
a first section having a porous region disposed in the coating composition in the reservoir, and
a second section having a porous region in fluid communication with the porous region of the first section, the second section being disposed over the first section so as to provide a sealed space between the second section and the coating composition in the reservoir, wherein the second section includes the coating surface to coat the implantable medical device;
a support element to support an implantable medical device in close proximity to or in contact with the coating surface of the applicator;
a temperature controller in communication with the applicator, the support element or the reservoir for heating or cooling the coating composition; and
a pressurizing device in communication with the applicator or the reservoir for enhancing the conveyance of the coating composition from the reservoir to the coating surface wherein the pressurizing device is in fluid communication with the sealed space.
