Minimally invasive spinal disc stabilizer and insertion tool

摘要

The invention relates to a spinal implant to be inserted between two vertebra to support and stabilize adjacent vertebra and allow for physiological motion. One embodiment of the implant includes an upper assembly and a lower assembly, where the assemblies are adapted to articulate relative to one another. This implant also includes elongate elements that are deployable between a closed position and an open position. Portions of the implant can interlock to form various shapes. The invention includes an implantable device to support the vertebrae, and a minimally invasive method for inserting and deploying the device within the intervertebral space.
