An RF treatment device according to the present invention includes one or two radio frequency electrode holders each having multiple electrodes arranged to create a transmural lesion through tissue. The treatment device is placed with one holder placed on the endocardial surface of the heart wall with the electrodes protruding towards the epicardial surface of the heart and the other optional holder placed on the epicardial surface of the heart with the electrodes protruding towards the endocardial surface of the heart forming a bipolar arrangement of equally spaced electrodes. The embodiments of the present invention are described for use in creating a transmural lesion in heart tissue to treat atrial fibrillation by blocking the passage of abnormal electrical currents through the heart. However, the devices and methods may also be used to create continuous transmural lesions in heart tissue and other body organs and tissues to treat other conditions. Although the invention is primarily described with respect to the application of RF bi-polar energy, the devices may also be used to apply other types of energy, such as cryo, ultrasound, microwave, heat, or other electrical means of providing an interruption to the abnormal electrical circuits at given regions.
