1. A method of ablating target tissue including a non-linear area of tissue in a left atrium of a patient, the method comprising:

  • selecting an ablation apparatus having an ablator with a tissue engagement section;

    penetrating a chest cavity of the patient;

    identifying the target tissue;

    positioning the ablation apparatus adjacent to the target tissue so that the tissue engagement section can transfer ablation energy to the target tissue; and

    energizing the tissue engagement section with ablation energy in order to create a footprint on the non-linear area of tissue in the left atrium and to reduce an overall mass of excitable tissue in the left atrium.
