  • Patent number: 8956682
    Abstract: The invention is directed to medical device coatings, such as coated guidewires and catheters, containing a visualization moiety providing color to the coating in ambient or applied light. The coating allows for visual or machine inspection of coating properties such as uniformity of coverage. In some embodiments the coatings include the visualization moiety and an activated UV photogroup, which is used to provide covalent bonding in the coating. The visualization moiety can be in particulate form and entrained in the coating, or can be covalently bonded to the hydrophilic polymer backbone. In other embodiments the visualization moiety includes a stilbene chemical group. Exemplary coatings include a hydrophilic vinyl pyrrolidone polymer, which can provide lubricity to the device surface, along with the colored properties.
