  • Patent number: 10206729
    Abstract: A self-locking cable gripper includes a housing having a void which tapers between openings at the housing's top and bottom. A collapsible member having a central passage is adjacent the bottom opening. A pair of half jaws are between the collapsible member and the top opening, sized such that they move towards each other as the jaws are moved toward the bottom opening due to the taper of the void. The top and bottom openings, central passage, and inner surfaces of the jaws define a channel capable of receiving a cable passed through the housing from its bottom to its top opening. When the cable is pulled in the direction opposite that with which it was installed, the half jaws are drawn toward the housing's bottom opening such that their inner surfaces are urged towards each other, thereby locking the cable in place while it is under tension.

  • Publication number: 20160324646
    Abstract: A replacement device for resurfacing a joint surface of a femur and a method of making and installing such a device is provided. The custom replacement device is designed to substantially fit the trochlear groove surface, of an individual femur, thereby creating a “customized” replacement device for that individual femur and maintaining the original kinematics of the joint. The top surface is designed so as to maintain centrally directed tracking of the patella perpendicular to the plane established by the distal end of the femoral condyles and aligned with the center of the femoral head.

  • Patent number: 8771281
    Abstract: A replacement device for resurfacing a joint surface of a femur and a method of making and installing such a device is provided. The custom replacement device is designed to substantially fit the trochlear groove surface, of an individual femur. Thereby creating a “customized” replacement device for that individual femur and maintaining the original kinematics of the joint. The replacement device may be defined by four boundary points, and a first and a second surface. The first of four points is 3 to 5 mm from the point of attachment of the anterior cruciate ligament to the femur. The second point is near the bottom edge of the end of the natural articulatar cartilage. The third point is at the top ridge of the right condyle and the fourth point at the top ridge of the left condyle of the femur.
