Zusammenfassung:A method for ablating target tissue includes the steps of: (a) delivering an ablation balloon catheter to the target tissue, wherein the ablation balloon catheter includes a compliant balloon, a visualization device; and an electrode array that is visible to the visualization device, each electrode being configured to deliver ablation energy, wherein the electrode array is independently movable relative to the compliant balloon; (b) isolating the target tissue such that at least one electrode of the electrode array is in contact with the target tissue; and (c) delivering the ablation energy to those electrodes of the electrode array that are confirmed, using the visualization device, to be in contact with target tissue.
