Radiopaque coating for biomedical devices

摘要

A medical device has a porous metallic coating that can withstand the high strains inherent in the use of such devices without delamination. A coating of the metal is applied to a medical device, such as a stent, by vapor deposition so that the thermomechanical properties of the stent are not adversely affected. The coating preferable has high emissivity. The coating is applied via a generally oblique coating flux or a low energy coating flux.
