  • Multi-lobe artificial spine joint
    Patent number: 10098752
    Abstract: An artificial disc is provided which more closely matches the movement of the natural spine. The artificial disc uses one or more projections and corresponding recesses to provide a sliding articulation. The artificial joint is inherently stable in that compressive forces placed on the disc such as the weight placed upon the joint or the tension of surrounding tissues urges the joint towards a neutral position and not farther away from a neutral position.
    Type: Grant
    Filed: October 16, 2017
    Date of Patent: October 16, 2018
    Assignee: DIMICRON, INC.
    Inventors: Bao-Khang Ngoc Nguyen, David P. Harding

  • Thick sintered polycrystalline diamond and sintered jewelry
    Patent number: 9820539
    Abstract: Methods of forming larger sintered compacts of PCD and other sintered ultrahard materials are disclosed. Improved solvent metal compositions and layering of the un-sintered construct allow for sintering of thicker and larger high quality sintered compacts. Jewelry may also be made from sintered ultrahard materials including diamond, carbides, and boron nitrides. Increased biocompatibility is achieved through use of a sintering metal containing tin. Methods of sintering perform shapes are provided.

  • Use of Ti and Nb cemented in TiC in prosthetic joints
    Patent number: 8603181
    Abstract: An improved composition of titanium sintered titanium carbide is provided. The composition provides an improved degree of strength and toughness and improved compatibility with medical imaging. The composition provides good compatibility with sintered polycrystalline diamond, achieving a good mechanical fit in terms of the combined compressibility and thermal expansion during the sintering process to minimize stress or cracking between the substrate and the diamond layer.
