  • Publication number: 20200061242
    Abstract: 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.

  • Patent number: 10516169
    Abstract: An apparatus and method is described to coat small and large quantities of solid particles using atomic layer deposition, with increased material utilization and decreased cycle times. The resulting higher coating efficiency ALD process is achieved by a controlled pressure differential acting across a rotating porous vessel that contains a plurality of solid particles. The apparatus is comprised of two coaxial cylindrical porous vessels with a means for one to rotate, and a two stage rotary feedthrough with a specialized hollowed out shaft, which enables both rotation of the vessel and reactant, purge, and product gas transport across a particle bed that undergoes mixing.
