  • Patent number: 10966734
    Abstract: A surgical instrument includes a first member defining an axis and having a scraping surface configured to scrape tissue. A second member includes a cutting surface that is rotatable relative to the first member. The second member has a maximum length defined by opposite end surfaces of the second member. The end surfaces are each disposed within the first member. A third member includes an outer surface defining at least a portion of a passageway configured for disposal of the scraped tissue. The third member is fixed with the first member. The cutting surface is rotatable relative to the third member to transfer the scraped tissue along the axis. Systems and methods are disclosed.

  • Publication number: 20200315813
    Abstract: A surgical implant and a method for the making the surgical implant is provided. The surgical implant includes various granules incorporated into an upper surface and a lower surface of a body portion thereof. The granules can be pressed into the upper surface and the lower surface via physical force using at least one mold portion. The physical force applied by the at least one mold portion can deform and/or extrude the upper surface and the lower surface to impregnate these surfaces with the granules. The granules can provide the implant with bioresorbable and/or mechanically-reinforced properties.

  • Patent number: 9770338
    Abstract: A prosthetic system for implantation between upper and lower vertebrae comprises an upper joint component. The upper joint component comprises an upper contact surface and an upper articulation surface. The system further includes a lower joint component. The lower joint component comprises a lower contact surface and a lower articulation surface configured to movably engage the upper articulation surface to form an articulating joint. The articulating joint is adapted for implantation within a disc space between the upper and lower vertebrae, allowing the upper and lower vertebrae to move relative to one another. The system further includes a bridge component extending posteriorly from one of either the upper or lower joint components and from the disc space. The bridge component has a distal end opposite the one of the either upper or lower joint components. The distal end of the bridge component comprises a connection component adapted to receive a fastener.
