First Claim
Patent Images
1. A method of performing percutaneous interbody spinal fusion on adjacent vertebrae of a patient comprising the steps of:
- creating a percutaneous access opening into the patient, the access opening being less than 10 mm wide; and
using indirect visualization, without retraction, to place a neural monitoring probe into the percutaneous access opening to establish a surgical path to an intervertebral disc via neural monitoring through the percutaneous access opening;
after establishing the surgical path via neural monitoring, creating a cavity in an intervertebral disc space of the adjacent vertebrae by inserting an instrument through the surgical path, without retraction;
after creating the cavity, evaluating the created cavity;
inserting an expandable container into the created cavity through the surgical path in a collapsed state, wherein the container in the collapsed state is sized to fit through the less than 10 mm wide percutaneous access opening without retraction of the access opening; and
after insertion the container into the cavity, filling the container with fill material through the surgical path via the percutaneous access opening, without retraction, wherein the fill material promotes bony fusion and stabilization of the adjacent vertebrae.

Abstract
A method of performing percutaneous interbody spinal fusion on adjacent vertebrae in a patient including the steps of: creating an access opening on the patient, the access opening being less than 10 mm wide, using indirect visualization: establishing a surgical path through the access opening via neural monitoring, creating a cavity in a disc space between the adjacent vertebra, evaluating the created cavity, inserting a container sized and configured to fit through the less than 10 mm access opening into the cavity and filling the container with fill material.

4. A method for performing percutaneous interbody spinal fusion on adjacent vertebrae of a patient comprising the steps of:
-
providing imaging equipment adapted to provide indirect visualization of the patient during the percutaneous interbody spinal fusion procedure and present images of the patient'"'"'s internal anatomy on a viewing screen visible to a surgeon performing the percutaneous interbody spinal fusion procedure; inserting a neural stimulating component into the patient'"'"'s tissues to aid the surgeon in creating a percutaneous surgical path through a less than 10 mm percutaneous access opening to a disc between the adjacent vertebrae; forming the less than 10 mm percutaneous access opening to a disc between the adjacent vertebrae; inserting at least one disc cavity creation tool through the percutaneous surgical path, the tool configured to create a cavity in an intervertebral disc space of the adjacent vertebrae; creating the cavity in an intervertebral disc space of the adjacent vertebrae with the at least one disc cavity creation tool; inserting a discectomy evaluation device through the percutaneous surgical path; inserting through the percutaneous surgical path an expandable container sized and in a collapsed state to fit through the less than 10 mm percutaneous access opening; filling the collapsed container intervertebral disc space through the percutaneous surgical path with fill material to expand the container and promote bony fusion to stabilize a spinal motion segment; and providing instructions for use of the container to perform percutaneous interbody spinal fusion on adjacent vertebrae of a patient. - View Dependent Claims (5, 16)

6. A method of performing percutaneous interbody spinal fusion on adjacent vertebrae of a patient comprising the steps of:
-
creating a percutaneous access opening in the patient, the access opening being less than 10 mm wide; establishing a surgical path through the percutaneous access opening, without retraction and without directly viewing the surgical path, to a vertebral disc of the patient between adjacent vertebrae to be fused; inserting at least one disc cavity creation tool through the surgical path and creating a cavity in an intervertebral disc space of the adjacent vertebrae; after creating the cavity in the intervertebral disc space, inserting an expandable container sized and configured to fit through the less than 10 mm access opening, without retraction, into the cavity; and filling the container after insertion into the cavity with fill material via the surgical path to promote bony fusion to stabilize a spinal motion segment. - View Dependent Claims (7, 8, 17)
