5. A method of treating a spinal tumor, the method comprising:
obtaining an ablation device, the ablation device comprising:
a first electrode; and
a second electrode;
inserting a thermal energy delivery probe into a utility channel of the ablation device prior;
after inserting a thermal energy delivery probe into the utility channel of the ablation device, activating the ablation device such that an electrical current flows between the first electrode and the second electrode via spinal tissue of a patient; and
delivering bone cement through the utility channel of the ablation device, thereby filling an opening within a vertebra of the patient.
