    • An electrosurgical probe including a probe body which defines a longitudinal probe axis. The electrosurgical probe also includes a first and second conductive electrode, each disposed along the probe axis. The surface area of the first conductive electrode is greater of the surface area of the second conductive electrode. The ratio of the surface area of the first conductive electrode to the surface area of the second conductive electrode may be adjustable. Another aspect of the present invention is an electrosurgical probe having a probe body which defines a single longitudinal probe axis. The electrosurgical probe of this aspect of the invention further includes more than two electrodes operatively disposed at separate and distinct positions along the axis of the probe body. The electrodes may be selectively connected to one of or a combination of a stimulation energy source, an ablation energy source or a ground for either energy source. Another aspect of the present invention is a method of placing an electrosurgical probe such as described above for specific ablation procedures.
    • 电外科探头,其包括限定纵向探针轴的探针体。 电外科探头还包括沿着探针轴线设置的第一和第二导电电极。 第一导电电极的表面积大于第二导电电极的表面积。 第一导电电极的表面积与第二导电电极的表面积之比可以是可调节的。 本发明的另一方面是具有限定单个纵向探针轴线的探针体的电外科探针。 本发明的这个方面的电外科探头进一步包括多于两个电极,其操作性地设置在沿着探针主体的轴线的分离和不同位置。 电极可以选择性地连接到刺激能量源,消融能源或用于任一能量源的地面之一或组合。 本发明的另一方面是放置如上所述的用于特定消融手术的电外科探针的方法。
