  • Patent number: 8454988
    Abstract: Osteogenic bone implant compositions that approximate the chemical composition of natural bone are provided. The organic component of these implant compositions is osteoinductive despite the presence of the inorganic component and, further, is present in an amount sufficient to maximize the regenerative capabilities of the implant without compromising its formability and mechanical strength. The composition may be an osteoinductive powder, including demineralized bone matrix (DBM) particles, a calcium phosphate powder, and, optionally, a biocompatible cohesiveness agent. The powder may be combined with a physiologically-acceptable fluid to produce a formable, osteoinductive paste that self-hardens to form a poorly crystalline apatitic (PCA) calcium phosphate having significant compressive strength. The bone implant materials retain their cohesiveness when introduced at an implant site and are remodeled into bone in vivo.

  • Patent number: 5337608
    Abstract: A drive roller torque reference cartridge for calibrating a drive force tester. The reference cartridge uses a magnetic hysteresis brake assembly to controllably resist the rotation of the cartridge drive roller. The magnetic hysteresis brake assembly includes a cylindrical permanent magnet within the drive roller and a coaxial remanently magnetizable sleeve surrounding the drive roller. The drag created by the reference cartridge is substantially independent of the temperature and rotational speed of the drive roller.
