Patent ID: 7736360

Claim:
A method of treating tissue comprising: positioning a treatment system adjacent to an anatomical site, where the treatment system includes an ablation device, a first elongate arm and a second elongate arm, where the ablation device and second elongate arms are coupled by a flexible member that couples the ablation device to a distal portion of the second elongate arm such that the ablation device, the second arm and the flexible member define a closed loop assembly extending from the first elongate arm; stabilizing the closed loop assembly within the anatomical site by manipulating both elongate arms to force the closed loop assembly against tissue; advancing the ablation device through the first arm and positioning the ablation device using the flexible member such that the stabilized closed loop assembly stabilizes the ablation device; treating a first region of tissue adjacent to the flexible member with the ablation device; and comprising placing at least one electrode against tissue to transmit and receive electrophysiological signals from the tissue where the least one electrode is located on the flexible member.
