Multi-probe system using bipolar probes and methods of using the same

A method of lesioning for targeting a region of a vertebral body of a patient, the method comprising:

• inserting a first introducer assembly into a first target location of the vertebral body to provide a first trajectory to access the vertebral body, the first introducer assembly including a first cannula;
• inserting a second introducer assembly into a second target location of the vertebral body to provide a second trajectory to access the vertebral body, the second introducer assembly including a second cannula;
• inserting a first bipolar probe through the first cannula of the first introducer assembly, the first bipolar probe having a proximal end, an opposite distal end, and a first mid-longitudinal axis extending through the proximal end and the distal end thereof, the first bipolar probe including a first active tip at the distal end of the first bipolar probe, the first active tip including at least two electrodes;
• inserting a second bipolar probe through the second cannula of the second introducer assembly, the second bipolar probe having a proximal end, an opposite distal end, and a second mid-longitudinal axis extending through the proximal end and the distal end thereof, the second bipolar probe including a second active tip at the distal end of the second bipolar probe, the second active tip including at least two electrodes;
• positioning the first active tip of the first bipolar probe within the vertebral body;
• positioning the second active tip of the second bipolar probe within the vertebral body;
• supplying power to the first bipolar probe to create a first lesion formed ablating bone around the first active tip;
• and
• supplying power to the second bipolar probe to create a second lesion formed by ablating bone around the second active tip,
• wherein a first plane parallel to a cranial-caudal axis of the patient extends along the first mid-longitudinal axis of the first bipolar probe, a second plane parallel to the cranial-caudal axis of the patient extends along the second mid-longitudinal axis of the second bipolar probe, a third plane perpendicular to the first plane extends along the first mid-longitudinal axis, a fourth plane perpendicular to the second plane extends along the second mid-longitudinal axis, the first plane and the second plane intersect one another within the vertebral body, and the third plane and the fourth plane are parallel to one another and to a transverse plane of the patient, and wherein a first coronal plane extends through each of the first bipolar probe and the second bipolar probe, and the first bipolar probe and the second bipolar probe, after positioning of the first active tip and the second active tip within the vertebral body, overlap one another in directions aligned with the cranial-caudal axis in the first coronal plane.
