Abstract

Systems and methods are disclosed for treating back pain associated with a vertebral body of a patient. The system may include an external energy source configured to be positioned at a location external to the body of the patient, a linear configured to drive translation of the external source in one or more axes, a computer coupled to the external source and linear drive and programming executable on said computer for determining a target treatment site within or near the vertebral body based on acquired imaging data, positioning a focal point of the external energy source to substantially coincide with the target treatment site, and delivering a treatment dose of therapeutic energy at said target treatment site, wherein the treatment dose is configured to modulate a nerve within or near the vertebral body.

First claim

What is claimed is:

1. A method for treating back pain associated with a vertebral body of a patient, comprising:
imaging a vertebral body to generate one or more images of the vertebral body;
locating, based on said images, a portion of a sinuvertebral nerve within an epidural space associated with the vertebral body;
identifying one or more nerve branches associated with the vertebral body and emanating at a first end at a junction with the sinuvertebral nerve at a location external to the vertebral body and that course medially from the junction under a posterior longitudinal ligament,
percutaneously guiding a delivery assembly to the location external to the vertebral body,
wherein the delivery assembly comprises at least one lumen for advancing an imaging device and for advancing a treatment device;
isolating the one or more nerve branches for treatment,
wherein isolating the one or more nerve branches comprises verifying that the one or more nerve branches course under the posterior longitudinal ligament;
delivering the treatment device to the external location via the delivery assembly; and
denervating the one or more isolated nerve branches at a position at or near the junction with the sinuvertebral nerve,
wherein denervating the one or more isolated nerve branches comprises operating the treatment device at the position at or near the junction with the sinuvertebral nerve.

2. The method of claim 1 , further comprising dilating a space under the posterior longitudinal ligament to allow visualization of a foramen leading to the vertebral body prior to denervation of the one or more nerve branches.

3. The method of claim 1 , wherein the step of denervating the one or more isolated nerve branches comprises altering a conductive property of the one or more nerve branches.

4. The method of claim 1 , wherein the step of denervating the one or more isolated nerve branches comprises severing conduction across the one or more nerve branches.

5. The method of claim 3 , wherein altering a conductive property of the one or more nerve branches comprises one or more of: stimulation, alteration, blocking, or elimination of conduction across the one or more nerve branches sufficient to provide a therapeutic effect within or related to the vertebral body.

6. The method of claim 3 , wherein altering a conductive property of the one or more nerve branches comprises one or more of: heating, cooling, radiating, agitating, or altering the chemical composition of the one or more nerve branches sufficient to provide a therapeutic effect within or related to the vertebral body.

7. The method of claim 3 , wherein altering a conductive property of the one or more nerve branches comprises cutting or crimping the one or more nerve branches.

8. The method of claim 1 , wherein said denervating is effected by at least one of radiofrequency, ultrasound, radiation, steam, microwave, or laser.
