    Abstract: An apparatus for ablating at least a portion of an interior of a body structure includes a catheter with a catheter interior and a port formed in a body structure of the catheter. An ablation energy delivery device is at least partially positioned in the catheter interior. The ablation energy delivery device is configured to be advanced through the port into the interior of the body structure to a selected tissue site and deliver an ablation energy to the selected site. The ablation energy delivery device is configured to be coupled to an ablation energy source. A sensor is coupled to the ablation energy source. The sensor is positionable in the interior of the body structure and measures an impedance of at least a portion of the selected tissue site. A conductive medium introduction member is coupled to a source of a conductive medium and the catheter. A feedback control means is coupled to the sensor and the conductive medium source. The feedback control means provides a controlled delivery of the conductive medium to the selected tissue site in response to a level of measured impedance. A cable coupled to the ablation energy delivery device.

    Abstract: An apparatus for treating air way obstructions, includes a first arm including a proximal end and a distal end, the first arm distal end is inserted into the throat and positioned adjacent to a back surface of the tongue. A second arm has a proximal end and a distal end. The second arm is positioned under the jaw. A coupling member couples the first arm with the second arm, permitting rotational movement of each arm about a longitudinal axis of the coupling member. A plurality of RF electrodes are positioned in the first arm. The plurality of RF electrodes are advanced into the back of the tongue and retracted out of the tongue and into the first arm, ablating a selected area of the back of the tongue.
