Patent ID: 8216229

Claim:
A method for ablating tissue with a probe assembly comprising an elongated shaft having a plurality of ablation electrodes carried by a distal end of the elongated shaft, each of the electrodes having a lumen therein, the probe assembly further comprising a handle member rotatable relative to the elongated shaft and containing a delivery port configured to communicate with a selected one of the electrode lumens, the method comprising: inserting a cannula having a lumen therein into a treatment region; advancing the elongated shaft distally within the lumen of the cannula such that one of the ablation electrodes penetrates a wall of a vessel adjacent to or in the treatment region; rotating the handle member relative to the elongate shaft to selectively place the delivery port in communication with the lumen of the electrode penetrating the wall of the vessel; inserting an occlusion element into the vessel via the lumen of the electrode penetrating the wall of the vessel; and delivering radiofrequency energy to the treatment region via at least one of the electrodes.
