Abstract: 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.

Abstract: Embodiments of a sizing device that can be used to measure the size of airways lumens, such as those connected to lungs. The sizing device can have different expandable elements in order to accurately and consistently measure the particular dimensions of a lumen. In some embodiments, markings viewable by a user can be used to determine the particular size.

Abstract: A medical device system for the delivery of energy to a region of a patient's anatomy is provided. An introducer tube defines a lumen therein and bears a first electrode. A second electrode is movable within the lumen between a retracted position and an extended position. In the retracted position, the second electrode is substantially disposed within the lumen. In the extended position, the second electrode extends at least partially beyond the distal end of the introducer tube. In one form, the introducer tube is configured to substantially hold the second electrode within the lumen in a predetermined orientation in the extended position, and the introducer tube prevents the second electrode from substantially rotating within the lumen of the introducer tube during movement into the extended position. In one form, the introducer tube is more flexible in a first plane than in a second plane.
