The present invention provides compositions and methods for an improved coating for medical devices. Provided is a biofunctional coating composition comprising at least one binding domain that has binding specificity for a metallic surface material of a medical device, and at least one binding domain that has binding specificity for cells of endothelial cell lineage. Methods for coating a metallic surface of a medical device, and for manufacturing of a medical device, comprise contacting the metallic surface to be coated with the biofunctional coating material in an amount effective to form a coating, and may further comprise contacting the coated surface with cells of endothelial cell lineage to bind the cells of endothelial cell lineage to the coated surface.

La présente invention concerne des compositions et des procédés pour un meilleur revêtement de dispositifs médicaux. L'invention concerne une composition de revêtement biofonctionnel comprenant au moins un domaine liant qui a une spécificité de liaison vis-à-vis d'une matière de surface métallique d'un dispositif médical et au moins un domaine liant qui a une spécificité de liaison vis-à-vis de cellules d'une lignée de cellules endothéliales. Des procédés servant à recouvrir une surface métallique d'un dispositif médical et à fabriquer un dispositif médical consistent à mettre la surface métallique à recouvrir en contact avec la matière de revêtement biofonctionnel en quantité efficace pour former un revêtement et peuvent en outre consister à mettre la surface recouverte en contact avec des cellules d'une lignée de cellules endothéliales pour fixer les cellules de la lignée de cellules endothéliales à la surface recouverte.
