| 摘要 |
An intraluminal device having an adhesive primer coat formed of a carbonaceous material and a lubricious top coat of a hydrophilic polymeric material. The invention also comprises the methods of making such intraluminal devices. The primer coat of the invention may comprise pure carbon, or a carbon based material such as a polymer. Preferably, the primer coat has a thickness of about 0.1 to about 2 mum. In a presently preferred embodiment, the primer coat is applied using chemical vapor deposition (CVD), but in certain embodiments, physical vapor deposition (PVD) may be suitable. The deposited primer coat forms an effective substrate for adhesion of the hydrophilic polymer top coat. |
