  • Multi-lobe artificial spine joint
    Patent number: 8603169
    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: April 12, 2012
    Date of Patent: December 10, 2013
    Assignee: Dimicron, Inc.
    Inventors: Bao-Khang Ngoc Nguyen, David P. Harding

  • THICK SINTERED POLYCRYSTALLINE DIAMOND AND SINTERED JEWELRY
    Publication number: 20110146348
    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.
