Abstract
Devices and methods for ablating a selected tissue volume, such as for ablating tumor, are disclosed. In certain embodiments, the ablation devices include a low-conductivity, tissue-piercing tip, an adjustment mechanism for selectively adjusting the length of an exposed portion of the electrode, for producing ablation volumes of desired geometry. In other embodiment, the methods allow the adjustment of the length of the exposed electrode portion be carried out by moving an insulative sleeve along the electrode.
