    Abstract: A cell necrosis apparatus includes an introducer with a tissue piercing distal end. An RF electrode device includes a first RF electrode with a tissue piercing distal end, a second RF electrode with a tissue piercing distal end, and a third RF electrode with a tissue piercing distal end. The first and second electrodes each have an exterior non-insulated energy delivery surface and an exterior opposing insulated surface. The first, second and third RF electrodes are deployable from the introducer with the first and second RF electrodes exterior non-insulated energy delivery surfaces facing and surrounding the third RF electrode.

    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.
