  • Publication number: 20170348115
    Abstract: An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone or vertebral discs. The device can have multiple flat sides that remain flat during expansi A method of repairing tissue is also disclosed. Devices and methods for adjusting (e.g., removing, repositioning, resizing) deployed orthopedic expandable support devices are also disclosed. The expandable support devices can be engaged by an engagement device. The engagement device can longitudinally expand the expandable support device. The expandable support device can be longitudinally expanded until the expandable support device is substantially in a pre-deployed configuration. The expandable support device can be then be physically translated and/or rotated.

  • Patent number: 8936627
    Abstract: Expandable support devices for tissue repair are disclosed. The devices can be used to repair hard or soft tissue, such as bone or vertebral discs. A method of repairing tissue is also disclosed. Surgical devices and methods for adjusting (e.g., removing, repositioning, resizing) deployed orthopedic expandable support devices are also disclosed. The expandable support devices can be engaged and surgically implanted by an engagement device and affixed to bone to provide stability and support for the devices. The expandable support devices are attachable to spinal fixation devices such as screws or plates, and may be used to support such devices when placed in weakened or damaged areas of bone.
