A novel medical device thin film coating is disclosed. The coating may be produced by sputtering, CVD, MOCVD, or ALD. The conformal coating has dual antimicrobial and osseointegrative properties and comprises TiO2 and Ta2O5 or intermediate phases. The TiO2 provides antimicrobial properties via photocatalytic behavior in the visible or near visible light region and the Ta2O5 provides improved osseointegration. The TiO2 and Ta2O5 may be doped with other cations. The coating combination may also be patterned into opened regions of one coating material on a continuous layer of the other coating material by using a partially decomposable organic patterning material between the layers.
