Apparatus and method for ablating target tissue including a non-linear area of tissue in the left atrium of a patient. The method can include selecting an ablation apparatus having an ablator with a tissue engagement section, penetrating a chest cavity of the patient, and identifying the target tissue. The method can also include positioning the ablation apparatus adjacent to the target tissue so that the tissue engagement section can transfer ablation energy to the target tissue. The method can further include 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.
1. An ablation apparatus for ablating target tissue of a patient, the ablation apparatus comprising: an insertion tool having a proximal end, a distal end, and a lumen;an ablator including a conductor and a tissue engagement portion, the conductor having a source end extending from the proximal end
1. An ablation apparatus for ablating target tissue of a patient, the ablation apparatus comprising: an insertion tool having a proximal end, a distal end, and a lumen;an ablator including a conductor and a tissue engagement portion, the conductor having a source end extending from the proximal end of the insertion tool and a delivery end connected to the tissue engagement portion, the ablator removably inserted in the lumen, wherein the tissue engagement portion includes a skirt and the delivery end includes an adhesive tongue inside the skirt, the tongue moveable within the skirt to engage target tissue, and the skirt affixing the ablator to target tissue by a vacuum; andan energy source connected to the conductor;the insertion tool configured to be inserted into a patient so that the distal end is adjacent the target tissue;wherein the ablation apparatus is configured such that:the conductor is operable to urge the ablator out of the lumen to engage target tissue;energy conducted from the energy source to the ablator is configured to create a footprint on target tissue to reduce an overall mass of excitable tissue. 2. The ablation apparatus of claim 1 and further comprising a sensor connected to the ablator to sense the target tissue. 3. The ablation apparatus of claim 1 and further comprising a mapping tool to visualize the tissue engagement portion of the ablator. 4. The ablation apparatus of claim 1 wherein the insertion tool includes a catheter. 5. The ablation apparatus of claim 1 the skirt is configured to receive fluid for conducting the energy to the target tissue. 6. The ablation apparatus of claim 5 wherein the fluid is electrically conductive. 7. The ablation apparatus of claim 5 wherein the fluid is caustic. 8. The ablation apparatus of claim 5 wherein the fluid is thermally conductive. 9. The ablation apparatus of claim 1 wherein the ablator includes a chemical delivery system. 10. The ablation apparatus of claim 9 wherein the chemical delivery system is configured to provide at least one of diffusion, iontophoresis, mechanical injection, needle-less injection, and controlled slow-release delivery.
