Spinal motion preservation assemblies adapted for use in a spinal motion segment are disclosed including the process for delivering and assembling the spinal motion preservation assemblies in the spinal motion segment via an axial channel created with a trans-sacral approach. Many of the spinal motion preservation assemblies make use of a dual pivot. A number of different embodiments of spinal motion preservation assemblies are disclosed which include at least one component adapted for elastic deformation under compressive loads. The disclosed mobility preservation assemblies provide for dynamic stabilization of the spinal motion segment. Other variations and implementations of the teachings are disclosed, including the sheathed delivery of membranes in order to protect the membranes before and during deployment.
A membrane delivery tool for delivering a membrane to be used in a prosthetic nucleus wherein the delivery tool is adapted to have a membrane attached to the delivery tool and then covered by a movable sheath so that the membrane may be protected as the delivery tool is introduced into a patient's body and the sheath may be removed to expose the membrane when the membrane is in position to receive prosthetic nucleus material within an intervertebral disc space.
A driver for delivering an insert to a bone anchor, the bone anchor having an internal cavity with a set of internal threads, the driver adapted to rotate with respect to a bone anchor that is anchored in a vertebral body in order to engage external threads on the insert with the internal threads in the bone anchor and axially advance the threadably engaged insert within the bone anchor while simultaneously preventing the bone anchor from rotating with respect to the vertebral body.
A driver for delivering an insert to an implanted bone anchor the driver adapted to positively engage the insert through use of an expanding mandrel which is selectively expanded and released through an adjustment means that is on the portion of the driver that is not inserted into a body during the delivery of the insert to the implanted bone anchor.
A threaded sleeve with a distal end with a set of external threads for establishment of a threaded engagement with a set of internal threads in an implanted bone anchor, and a proximal end with a set of internal threads for engagement with a distraction driver that moves axially through the interior of the implanted bone anchor and pushes an object away from the implanted bone anchor and the threadedly engaged threaded sleeve.
A method of delivering a motion preservation assembly into a vertebral motion segment, the method comprising:
