Abstract:
1. A method of removing an organic film from a selected portion of an implantable medical device, comprising: using an infrared laser set at a first value for an operational parameter, tracing the perimeter of a selected portion of the implantable medical device to ablate an organic film along the perimeter of the selected portion, wherein the organic film comprises a polymer bonded to the implantable medical device with a primer compound and the polymer substantially transmits infrared radiation; using an infrared laser set at a second value for the operational parameter, scanning the selected portion of the implantable medical device to heat the surface of the device within the perimeter of the selected portion and thereby separate the organic film from the surface of the device within the perimeter of the selected portion; and mechanically removing the chemically separated organic film from the surface of the implantable medical device within the perimeter of the selected portion of the device to expose the selected portion.
