  • Patent number: 9445848
    Abstract: An implant to separate a vertebral cut has an upper portion, lower portion, and inner member. The inner member communicates with a swivelable coupling located at each end of the inner member. Each swivelable coupling also interacts with a respective one of the upper and lower portion, within an inner bore thereof. Movement of the inner member relative to one or both of the upper and the lower portions, via one or both swivelable couplings, translates the upper portion away from the lower portion, about a vertebral cut, to widen the vertebral cut and expand the spinal canal. Swivelable action of the couplings allows angulation of the inner member, relative to a longitudinal axis of the implant, to accommodate a natural lateral shift occurring during a widening of a vertebral cut.

  • Patent number: 4679957
    Abstract: A ball joint assembly having a primary ball and a primary bearing surface. The primary ball is coaxially attached to a main shaft which pivots near the point of contact between the primary ball and the primary bearing surface. The main shaft controls a coaxially connected secondary ball spaced apart from the primary ball and closely spaced from a secondary bearing surface, similar in orientation to the primary surface, so that the secondary ball floats freely at some predetermined distance from the secondary bearing surface. The secondary ball contacts a normally closed microswitch. As the primary bearing surface wears the main shaft rises bringing the secondary ball toward the secondary bearing surface and away from the microswitch. Eventually the secondary ball will contact the secondary bearing surface and the microswitch will be activated, causing a warning light to illuminate, thereby signalling wearout of the ball joint without catastrophic failure.
