摘要：
Embodiments of the disclosure include lubricious coatings. In an embodiment the disclosure includes a lubricious coating for a medical device including first and second coated layers. The first coated layer is between the second coated layer and the device surface and includes a vinyl pyrrolidone polymer and a photo reactive group. The second coated layer is in direct contact with the first coated layer and is a top coating that includes an acrylic acid polymer. The second coated layer can optionally include photoreactive groups. The coating was found to have a very low number of particulates (e.g., 10 mm or greater) which is very desirable for in vivo use.
