Abstract
A method of manufacturing a coated medical device, includes applying a first low-friction coating to a surface of the medical device. The first low-friction coating includes a first colored pigment, such as a relatively light colored pigment. After applying the first low-friction coating, a suitable laser and laser energy is selectively applied to different areas of the coated medical device. The laser ablates or removes the first low-friction coating (at the different areas of the medical device) to leave the bare metal substrate of the medical device exposed. After selectively removing one or more portions of the first low-friction coating, a second low-friction coating is applied to the exposed bare metal substrate of the medical device and suitably cured. The second low-friction coating includes a second colored pigment, such as a relatively dark colored pigment, wherein the second colored pigment contrasts the first colored pigment of the first low-friction coating.
