1. A treatment system for accessing and ablating a basivertebral nerve within a vertebral body of a patient, the system comprising: a radiofrequency generator; a fluoroscopic imaging device; a first outer cannula; a first inner stylet adapted to be inserted within the first outer cannula, the first inner stylet comprising a sharp tip adapted to facilitate penetration into the vertebral body; a first channeling tool adapted to be inserted through the first outer cannula after removal of the first inner stylet in order to create a first working channel beyond a first path formed by the first inner stylet within the vertebral body; a first radiofrequency probe adapted to be inserted through the first outer cannula after removal of the first channeling tool to a treatment zone within the vertebral body under real time image visualization performed by the fluoroscopic imaging device, wherein the first radiofrequency probe comprises a bipolar probe having a first two electrodes, wherein the first two electrodes comprise a first active electrode and a first return electrode, wherein the first active electrode is positioned at a distal tip of the first radiofrequency probe, wherein the first return electrode is spaced apart proximally from the first active electrode, wherein the distal tip of the first radiofrequency probe is adapted to traverse through bone tissue of the vertebral body, wherein the first radiofrequency probe has a diameter between 1 mm and 5 mm, a second outer cannula; a second inner stylet adapted to be inserted within the second outer cannula, the second inner stylet comprising a sharp tip adapted to facilitate penetration into the vertebral body; a second channeling tool adapted to be inserted through the second outer cannula after removal of the second inner stylet in order to create a second working channel beyond a second path formed by the second inner stylet within the vertebral body; a second radiofrequency probe adapted to be inserted within the vertebral body and advanced to the treatment zone under real time image visualization performed by the fluoroscopic imaging device, wherein the second radiofrequency probe comprises a bipolar probe having a second two electrodes, wherein the second two electrodes comprise a second active electrode and a second return electrode; wherein the second active electrode is positioned at a distal tip of the second radiofrequency probe, wherein the distal tip of the second radiofrequency probe is adapted to traverse through bone tissue of the vertebral body, wherein the second return electrode is spaced apart proximally from the second active electrode, wherein the second radiofrequency probe has a diameter between 1 mm and 5 mm, wherein the first and second radiofrequency probes are electrically coupled to a connector that integrally couples the first and second radiofrequency probes to the radiofrequency generator, wherein the radiofrequency generator is configured to apply radiofrequency energy within a frequency range between 400 kHz and 600 kHz to the first and second radiofrequency probes for a duration of time sufficient to ablate a basivertebral nerve within the treatment zone, wherein the first radiofrequency probe and the second radiofrequency probe each comprise one or more diagnostic devices configured to provide diagnostic information in connection with treatment, wherein the one or more diagnostic devices comprise one or more sensors and one or more cameras, and wherein the first and second radiofrequency probes each comprise one or more lumens configured to facilitate circulation of cooling fluid; and a fluid source configured to facilitate the circulation of the cooling fluid through the one or more lumens of the first and second radiofrequency probes.
