  • Patent number: 10646234
    Abstract: Instruments and methods that allow for a minimally invasive way to probe, locate, and cut a meniscus during a meniscectomy procedure. The instrument is a single hybrid probe/cutter instrument provided with both probing and cutting means that allow probing and cutting of the meniscus with the same hybrid instrument. A minimally invasive technique for probing and cutting (resecting) a torn area of a meniscus by employing the single, hybrid probing/cutting instrument is also provided. The technique provides a consistently good-quality meniscus with improved cosmetic results, and is simple and easily reproducible, strong, and time-saving for meniscal repairs.

  • Patent number: 10064983
    Abstract: Techniques, mixtures and improved porous materials (interconnected porous constructs) that are capable of maintaining a sufficient porosity while conferring improved mechanical and physical strength to the final construct. A sacrificial construct (for example, a sacrificial material such as polymethyl methacrylate (PMMA)) is used to obtain an inverse porosity of the construct it was molded into. The process provides a less porous end material that may be used as an arthroplasty device or surgical implant (for example, an interference screw of suture anchor) among many other applications. The process employs a sacrificial material to reduce the porosity of the final construct to about 35%.

  • Patent number: 9295556
    Abstract: A femoral implant for total hip replacement includes a cage screw, a femoral head and a base plate provided between the cage screw and the femoral head, to minimize the stress transferred from the femoral head to the bone. The femoral implant may optionally include devices for lateral fixation (for example, internal and/or external screws for lateral fixation) and a device for minimizing micro-motion that is integral to, and extends from, the cage screw.

  • Patent number: 7943677
    Abstract: A method to create interconnected porosity in materials that can be poured or injected into a cast. The process allows the arrangement of interconnected volumetric porosity to be directed in materials that are poured or injected into a cast. This process allows a manufacturer to tailor porosity with any size, shape, and configuration with the dissolvable material used to create the pores. This procedure can be applied to medical materials to direct bone growth or implant attachment. These resulting porous materials can include, but is not limited to short fiber reinforced epoxy or epoxy.
