1. A method of isolating a portion of the left atrium with a device having first and second electrode support members and first and second electrodes respectively carried by the first and second electrode support members, the method comprising the steps of:
- positioning the first and second support members adjacent to respective atrial walls that are spaced from one another;
moving the first and second support members towards one another until the atrial walls are in contact with one another; and
transmitting energy to the atrial walls with at least one of the first and second electrodes.

3. A method as claimed in claim 1, wherein the step of moving the first and second support members towards one another until the atrial walls are in contact with one another comprises pivoting the first support member relative to the second support member until the atrial walls are in contact with one another.
-
4. A method as claimed in claim 1, wherein the step of moving the first and second support members towards one another until the atrial walls are in contact with one another comprises manipulating a handle until the atrial walls are in contact with one another.
-
5. A method as claimed in claim 1, wherein the step of transmitting energy to the atrial walls with at least one of the first and second electrodes comprises transmitting the energy from the first electrode to the second electrode through the atrial walls.
-
6. A method as claimed in claim 1, wherein the step of transmitting energy to the atrial walls with at least one of the first and second electrodes comprises coagulating atrial wall tissue.
-
7. A method as claimed in claim 6, wherein the step of transmitting energy to the atrial walls with at least one of the first and second electrodes comprises fusing the atrial walls to one another.
-
8. A method as claimed in claim 1, wherein the step of positioning the first and second support members adjacent to respective atrial walls that are spaced from one another comprises positioning the first and second support members adjacent to respective atrial appendage walls that are spaced from one another.
