Abstract:
This specification describes technologies relating to an intervertebral disc prosthesis used to strengthen and stabilize the spine. Implementations of the technology described herein comprise a surgical device that is implanted through a small surgical incision into a portion of a human intervertebral disc, various support tools used to insert such a surgical device, and a method by which the device is used to strengthen and stabilize the spine.

Claim (Index 20):
A method of implanting an intervertebral disc implant to preserve motion between adjacent vertebrae, comprising:\n penetrating an annulus fibrosus using a first tool to form an access opening with an initial size through the annulus fibrosus without excising any portion of the annulus fibrosus; introducing a plurality of dilators with successively larger diameters over the first tool to gradually increase the size of the access opening from the initial size to a final desired larger size without excising any portion of the annulus fibrosus; placing an outer cannula over an outermost dilator of the plurality of dilators until its distal end reaches the distal margins of the annulus fibrosus; removing the sequential dilators and the first tool from the outer cannula; performing a percutaneous nuclectomy through the outer cannula and the access opening while leaving the annulus fibrosus substantially intact to create a void defined by the annulus fibrosus; percutaneously delivering a deflated multi-chamber implant through the outer cannula into the void defined by the annulus fibrosus; and inflating the implant using an inflation style, wherein the chambers of the multi-chamber implant are inflated with at least two materials, at least one of which comprises a curable silicone.
