1. A method of accessing and ablating tissue within a vertebral body involving internal cooling, the method comprising:
inserting a first stylet within a first cannula;
percutaneously inserting the first stylet and the first cannula through skin of a patient;
advancing the first stylet and the first cannula within the vertebral body using a transpedicular approach through a first pedicle using real time image guidance;
removing the first stylet from the first cannula;
inserting a first channeling tool through the first cannula to create a first working channel beyond a first path formed by the first stylet within the vertebral body using real time image guidance;
removing the first channeling tool from the first cannula;
identifying a treatment zone within the vertebral body;
inserting a first radiofrequency probe through the first cannula to the treatment zone within the vertebral body using real time image guidance,
wherein the first radiofrequency probe comprises a bipolar probe having a first two electrodes, wherein the first two electrodes comprises a first active electrode and a first return electrode,
wherein the first radiofrequency probe has a diameter between 1 mm and 5 mm;
inserting a second stylet within a second cannula;
percutaneously inserting the second stylet and second cannula together through skin of the patient;
advancing the second stylet and the second cannula within the vertebral body using a transpedicular approach through a second pedicle using real time image guidance;
removing the second stylet from the second cannula;
inserting a second channeling tool through the second cannula to create a second working channel beyond a second path formed by the second stylet within the vertebral body using real time image guidance;
removing the second channeling tool from the second cannula;
inserting a second radiofrequency probe within the vertebral body through the second cannula and to the treatment zone using real time image guidance,
wherein the second radiofrequency probe comprises a bipolar probe having a second two electrodes, wherein the second two electrodes comprises a second active electrode and a second return electrode,
wherein the second radiofrequency probe has a diameter between 1 mm and 5 mm,
wherein the first and second radiofrequency probes are coupled to a connector that integrally couples the first and second radiofrequency probes to a single generator,
causing energy within a frequency range between 400 kHz and 600 kHz to be delivered to the treatment zone within the vertebral body using the first and second radiofrequency probes for a duration of time sufficient to ablate a basivertebral nerve at the treatment zone,
wherein the first radiofrequency probe and the second radiofrequency probe each comprise a plurality of diagnostic devices configured to provide diagnostic information relating to the treatment zone,
wherein the plurality of diagnostic devices comprise one or more sensors; and
causing cooling fluid to circulate through one or more lumens of at least one of the first and second radiofrequency probes to provide cooling.
