System and method for performing percutaneous spinal interbody fusion
First Claim
Patent Images
1. A method of performing percutaneous interbody spinal fusion on adjacent vertebrae of a patient, the method comprising:
- creating a percutaneous access opening into the patient;
using indirect visualization, without retraction, to establish a surgical path to an intervertebral disc through the percutaneous access opening;
after establishing the surgical path to the intervertebral disc through the percutaneous access opening, creating a cavity in the intervertebral disc by inserting an instrument through the surgical path, without retraction of the percutaneous access opening;
evaluating the cavity created in the intervertebral disc without retraction of the percutaneous access opening;
inserting an implantable device into the created cavity through the surgical path in an undeployed state, wherein the device in the undeployed state is sized to fit through the percutaneous access opening without retraction of the percutaneous access opening; and
after inserting the implantable device into the cavity, filling the device with fill material through the surgical path via the percutaneous access opening, without retraction of the percutaneous access opening, 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 a percutaneous access opening on the patient, using indirect visualization to establish a surgical path through the access opening via neural monitoring, creating a cavity in a disc space between the adjacent vertebra, without retraction, evaluating the created cavity, inserting a container sized and configured to fit through the access opening into the cavity and filling the container with fill material.

6. A method for performing percutaneous interbody spinal fusion on adjacent vertebrae of a patient, the method comprising:
-
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; forming a percutaneous surgical path to an intervertebral disc between the adjacent vertebrae; inserting at least one disc cavity creation tool through the percutaneous surgical path; creating the cavity in an intervertebral disc space of the adjacent vertebrae with the at least one disc cavity creation tool; evaluating the cavity created in the intervertebral disc; inserting through the percutaneous surgical path an expandable implant in an undeployed state; filling the collapsed expandable implant through the percutaneous surgical path with fill material to expand the expandable implant within the cavity in the intervertebral disc space to promote bony fusion of the adjacent vertebrae to stabilize a spinal motion segment; and providing instructions for use of the expandable implant to perform the percutaneous interbody spinal fusion procedure. - View Dependent Claims (7, 8, 9, 10, 19)

11. A method of performing percutaneous interbody spinal fusion on adjacent vertebrae of a patient, the method comprising:
-
creating a percutaneous access opening in the patient; establishing a percutaneous surgical path through the percutaneous access opening, without retraction of the percutaneous access opening and without directly viewing the surgical path, to a vertebral disc of the patient between the adjacent vertebrae to be fused; inserting at least one disc cavity creation tool through the percutaneous surgical path and creating a cavity in an intervertebral disc space of the adjacent vertebrae; evaluating the cavity created in the intervertebral disc space; after evaluating the cavity in the intervertebral disc space, inserting an expandable device sized and configured to fit through the access opening, without retraction of the percutaneous surgical path, into the cavity; and filling the expandable device, after insertion into the cavity, with fill material via the surgical path, wherein the fill material promotes bony fusion to stabilize a spinal motion segment. - View Dependent Claims (12, 13, 14, 15, 16, 17, 20)
