| 摘要 |
The present invention provides methods and apparatus for plasma treatment of tubing surfaces. In one aspect, the invention provides a method for treating a tubing surface which calls for generating a gaseous plasma within a spatially localized region of space by electron cyclotron resonance (ECR), and exposing the surface to this plasma for a selected time period to treat the surface. Subsequent to the plasma treatment, the treated surface can be optionally coated with a selected compound, such as a bioactive material, e.g., anti-biotic or anti-coagulants.
