Patents by Inventor Cornelia Prinz

Cornelia Prinz has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Antibacterial and osteoinductive implant coating, method of producing such coating, and implant coated with same
    Patent number: 9492588
    Abstract: A calcium phosphate/copper coating for an implant is provided which includes highly porous calcium phosphate and predominantly discontinuously distributed copper. The highly porous calcium phosphate first forms a highly porous calcium phosphate layer in which the copper has been incorporated so as to be discontinuously distributed, to form the calcium phosphate/copper coating. Further provided are a method of producing such a calcium phosphate/copper coating and an implant coated therewith.

  • Method for producing an anti-infective coating on implants
    Patent number: 8828552
    Abstract: The invention relates to a method for producing an anti-infective coating on implants that contain titanium or are composed of titanium. The aim of the invention is to provide a coating method with which it is possible, for implants made of titanium or that contain titanium, to combine the optimization of the mechanical properties achieved with the anodic oxidation type II with the optimization of the anti-infective properties. According to the invention, the implants are anodically oxidized in an alkaline solution, then metal having anti-infective properties is electrodeposited on said surface, and afterwards the oxide layer containing metal is solidified.
