  • Orthopedic implant extension
    Patent number: 6953479
    Abstract: A stem extension for surgical implants such as tibial or femoral knee implants. The stem extension is interposed between the stem and its load bearing component (i.e., tibial tray or condylar component) and angularly orients the attached stem relative to the load bearing component to facilitate positioning of the stem in the bone canal and alignment of the load bearing component with the mechanical axis of the leg. The extension includes a female taper that engages the load bearing component. The extension also includes a male taper having a longitudinal axis oriented at an angle relative to the longitudinal axis of the female taper. Engagement of the male taper with the stem thereby orients the stem at an angle relative to the longitudinal axis of the load bearing component.

  • Purge system and method for accelerating environmental stress tests
    Publication number: 20040000200
    Abstract: A method of actively transporting atmosphere, including gases and other fluids, to and from an inner compartment of a sealed system. The purged atmosphere is replaced with another atmosphere having target characteristics. A vacuum purge system pulls atmosphere from the sealed system, while a pressure-based system pushes atmosphere into the sealed system. Humidity corrosion tests are accelerated over prior methods because purged atmosphere is actively transported out of the sealed system and characteristic atmosphere is actively transported into the sealed system.
