摘要：
Devices, methods, and systems for the treatment of tissue using energy delivery. Specifically, certain embodiments may be used for the treatment of lung tissue, such as lung nodules, using RF ablation, via a catheter provided with a first electrode attached to a distal end of the catheter, wherein the first electrode is hollow, wherein the first electrode comprises a piercing tip configured to pierce through an airway wall and a second electrode received in a movable manner within the first electrode, wherein the second electrode is extendable from the first electrode to form a first extended configuration.
