Claim Text:
1. A surgical ablation probe, comprising: a cannula having a distal end and defining a longitudinal axis; a shaft disposed within the cannula and being movable along the longitudinal axis and relative to the cannula between a stowed position and a deployed position; an inner conductor disposed within the shaft, the inner conductor including a distal portion; a needle electrode electrically coupled to the distal end of the inner conductor; and a deployable ground plane assembly coupled to the distal end of the shaft and disposed within the cannula when the shaft is in the stowed position, wherein when the shaft is moved from the stowed position to the deployed position, the distal portion of the inner conductor and the deployable ground plane assembly extend past the distal end of the cannula thereby expanding deployable ground plane assembly radially from the distal end of the shaft.
