摘要:
Coatings, devices and methods are provided, wherein the contacting surface of a medical device with at least one contacting surface for contacting a bodily fluid or tissue, wherein long-lasting and durable bioactive agents or functional groups are deposited on the contacting surface through a unique two-step plasma coating process with deposition of a thin layer of plasma coating using a silicon-containing monomer in the first step and plasma surface modification using a mixture of nitrogen-containing molecules and oxygen-containing molecules in the second step. The two-step plasma coating process enables the implantable medical device to prevent both restenosis and thrombosis under clinical conditions. The invention also relates to surface treatment of metallic and polymeric biomaterials used for making of medical devices with significantly improved clinical performance and durability.
