Patent ID: 8652022

Claim:
A method of treating a treatment region within solid tissue of a patient using, a probe, the probe having a cannula and a handle, the cannula having a distal end, the method comprising introducing the cannula through tissue of the patient until the distal end of the cannula is located proximate to the treatment region, wherein a plurality of electrodes is disposed within the cannula while the cannula is introduced through the tissue; advancing the plurality of electrodes out of the distal end of the cannula into the treatment region; delivering energy through the plurality of electrodes; attaching the cannula to a probe holder and attaching the probe holder to an immobile object, wherein the probe holder and immobile object are both external to the patient to thereby substantially minimize movement of the treatment region with respect to the immobile object when the patient makes voluntary or involuntary movements that would otherwise cause movement of the treatment region with respect to the immobile object; and irradiating the treatment region with a therapeutically effective dose of an ionizing radiation from an externally located source while the plurality of electrodes remain at least partially advanced within the treatment region and while the cannula remains attached to the probe holder.
