Abstract: Embodiments disclosed herein are directed to 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: A device for tissue sampling that comprises a needle, a stylet and a sealing member. The needle comprises a distal tip, a proximal end, and one or more interior portions. The needle extends along a longitudinal axis extending between the distal tip and the proximal end. The stylet is moveably supported within the one or more interior portions of the needle. The sealing member Is moveably supported within the one or more interior portions of the needle and substantially conforms to the one or more interior portions, The distal tip is configured to obtain a tissue sample. The stylet and the sealing member are movable, along the longitudinal axis away from the distal tip so that a local vacuum is created at the distal tip so that obtained tissue samples can be aspirated into the needle.
