<p>A method of treating bone tissue (e.g., a tumor, such as an osteoid osteoma) is provided. The method comprises introducing an ablation probe into bone tissue, deploying at least one ablative element transversely from the probe into the bone tissue, and conveying ablation energy from the ablative element(s) to ablate the bone tissue. In one method, the ablative element(s) comprises a pair of ablative elements, in which case, the ablative elements are transversely deployed from the ablation probe in opposite directions. In another method, the ablative element(s) comprises a plurality of ablative elements, in which case, the ablative elements are transversely deployed outward from the ablation probe in a plane. The ablation energy conveyed from the ablative element(s) may have a non-spherical profile, e.g., an elongated profile, to match a non-spherical profile of the bone tissue to be treated.</p> |
