Coatings onto medical devices are increasing as recent advances seek to improve the capabilities of existing devices or enable new approaches. Included are radiopaque coatings on stents, silver based anti-microbial coatings to improve bio-compatibility and tribological layers having low friction and high hardness. Many of these devices have complicated shapes making uniform coating challenging and require precise composition and morphological control. Directed vapor deposition can apply conformal coatings of metals and ceramics onto these parts using non line-of-sight deposition. The ability to vary the coating porosity (from highly porous to completely dense) creates addition flexibility.
