MINIMALLY INVASIVE SYSTEMS, DEVICES, AND SURGICAL METHODS FOR PERFORMING ARTHRODESIS IN THE SPINE
First Claim
1. A system for percutaneous fusion of the spine comprisinga first instrumentation component that is sized and configured to achieve posterior percutaneous transpedicular access to an interior of a first targeted vertebral body through a pedicle of the vertebra,a second instrumentation component that is sized and configured to achieve percutaneous cephalad trans-disc access to an interior of a second targeted vertebral body at a next adjacent superior level to the first targeted vertebral body,a third instrumentation component that is sized and configured to achieve percutaneous disc cavity creation comprising a device for forming an enlarged cavity in the intervertebral disc space between the first and second targeted vertebral bodies, anda fourth instrumentation component that is sized and configured to achieve percutaneous disc cavity support comprising a support matrix placed in the enlarged cavity formed by the third instrumentation component and that is sized and configured to separate and hold the first and second vertebral bodies apart, to thereby distract nerve roots and relieve pressure on the nerves, and a device for conveying in a percutaneous manner a volume of a filling material into the support matrix that, over time, hardens to promote fusion of the targeted first and second vertebral bodies.

Abstract
Systems, devices, and methods achieve percutaneous fusion of the spine. The systems, devices, and methods percutaneously manipulate instrumentation to achieve posterior percutaneous transpedicular access to an interior of a first targeted vertebral body through a pedicle of the vertebra. The systems, devices, and methods percutaneously manipulate instrumentation through the achieved percutaneous transpedicular access, to achieve percutaneous cephalad trans-disc access to an interior of a second targeted vertebral body at a next adjacent superior level to the first targeted vertebral body. The systems, devices, and methods percutaneously manipulate instrumentation through the achieved percutaneous transpedicular access and percutaneous cephalad trans-disc access, to achieve percutaneous disc cavity creation comprising forming an enlarged cavity in the intervertebral disc space between the first and second targeted vertebral bodies. The systems, devices, and methods percutaneously manipulate instrumentation through the achieved percutaneous transpedicular access and percutaneous cephalad trans-disc access, to place a support structure in the enlarged cavity that achieves disc cavity support, into which a volume of a filling material is conveyed that, over time, hardens to promote fusion of the targeted first and second vertebral bodies.
