1. A medical device for spinal tumor ablation, the medical device comprising:
a first tubular conductor;
a tubular insulator extending through the first tubular conductor, wherein the tubular insulator comprises an exposed portion at a distal end of the tubular insulator, wherein the exposed portion of the tubular insulator is distal of the first tubular conductor,
a second tubular conductor extending through the tubular insulator such that a distal portion of the second tubular conductor is disposed distal of the insulator, wherein the second tubular conductor forms a utility channel that extends from a proximal opening of the second tubular conductor to a distal opening at a distal end of the second tubular conductor; and
a port disposed proximal of the second tubular conductor, wherein the port is configured to provide access to a proximal opening of the utility channel;
wherein a portion of the utility channel is used for at least one of obtaining a biopsy sample, positioning temperature sensors, or delivering cement to a vertebra of a patient.
