Claims20
A medical implant comprising iridium oxide, the iridium oxide having a plurality of Ir—O σ bonds and a plurality of Ir═O π bonds, the iridium oxide having a ratio of the Ir—O σ bonds to the Ir═O π bonds that is greater than 1.3.
A medical implant comprising iridium oxide, the iridium oxide having a plurality of Ir atoms having a mean valance state of less than 3.4+.
A method for making a medical implant comprising:
- placing a medical implant or precursor thereof in a physical vapor deposition processing chamber;
- and
- depositing iridium oxide on the medical implant or precursor thereof using a power of at least 750 watts, and a total pressure of between 3 mTorr and 7 mTorr.
