MULTI-LAYERED RADIOPAQUE COATING ON INTRAVASCULAR DEVICES

摘要

Intravascular devices having a radiopaque layer theron for visualization are provided. The devices further includes a capping layer on the radiopaque layer to prevent exposure of the radiopaque material to surrounding tissues. A method of coating the device is also provided. The method includes using a unbalanced magnetic field magnetron to generate, from a source, metal atoms for coating and bombarding ions for compression deposited metal atoms to the surface of the device.
