Compliant coatings for insertable medical articles are provided. In some aspects, the coating includes a diene polymer-containing layer, and a second coated layer that includes another polymer. The coating can be formed by coupling the polymer of the second coated layer to the first coated layer via latent reactive groups, such as photoreactive groups. In other aspects, the insertable medical article has a coating that provides different functional features to different surfaces of the article. The medical article can have a cylindrical shape with an interior surface having a first coating, and an exterior surface with a second coating, wherein the article also includes a plurality of openings.
L'invention porte sur des revêtements élastiques s'appliquant à des articles médicaux insérables. Selon certaines formes d'exécution, le revêtement comprend une couche contenant un polymère diène, et une seconde couche comprenant un autre polymère. Pour former le revêtement, on couple le polymère de la seconde couche à la première couche par des groupes réactifs latents, tels que des groupes photoréactifs. Selon d'autres formes d'exécution, l'article médical insérable comporte un revêtement dont les différentes surfaces présentent diverses caractéristiques fonctionnelles. L'article médical peut avoir une forme cylindrique dont la surface interne comporte un premier revêtement et la surface externe un second revêtement, l'article comprenant également une pluralité d'orifices.
