  • Patent number: 10123881
    Abstract: An electronically assisted artificial vertebral disc having an upper disc plate and a lower disc plate is disclosed. An actuator imparts movement to at least one of the upper and lower disc plates. A control device controls the actuator and the amount of movement between the disc plates. The actuator includes a plurality of either linear actuators or rotary actuators that are driven by electric motors in response to the control device. The control device includes at least a first sensor for detecting the position of the actuator and at least a second sensor for detecting the spatial orientation of at least one of the upper and lower disc plates. The control device also preferably includes a microprocessor that calculates the desired positions of the upper and lower disc plates and provides a control signal to the actuator to drive the upper and lower disc plates to their desired positions.

  • Patent number: 10045864
    Abstract: A trial implant system including a trial implant configured to be temporarily inserted into an intervertebral space defined by a superior vertebral body and an inferior vertebral body is disclosed. The trial implant may include a superior plate and an inferior plate coupled to the superior plate. The superior plate may have a first mating portion that defines a first articulating interface and the inferior plate may have a second mating portion that defines a second articulating interface. The second articulating interface may be configured to interact with the first articulating interface of the superior plate such that at least one of the superior plate and the inferior plate is capable of movement relative to the other. The first and second articulating interfaces may be primary or auxiliary articulating interfaces. For example, the first and second articulating interfaces may be corresponding curved surfaces or they may be corresponding engagement features.

  • Patent number: 9883945
    Abstract: An intervertebral disc is provided having an upper plate, a lower plate, and a core. The upper and lower plates include outer vertebral body contacting surfaces which are provided with attachment enhancing features to ensure bone integration. The attachment enhancing features shown include one or more fins, serrations and teeth. An opposite surface of the plates from the vertebral body contacting surfaces is formed with a recess which serves as a bearing surface for the core. In order to form an intervertebral disc with a lower disc height, at least one of the recesses is provided opposite a corresponding dome shaped portion on the vertebral body contacting surfaces. This allows the plates to be formed with a thinner profile for a smaller overall disc height. In addition to providing a lower overall height to the artificial disc, the dome shaped portion of the plates also provides a more anatomically shaped outer vertebral body contacting surface.
