Abstract
Methods, systems, and devices for enhancing the efficiency and efficacy of energy delivery and tissue mapping. One system includes a treatment element having a plurality of electrodes and an energy generator that is configured to deliver electric energy pulses to the electrodes in a variety of patterns. For example, electrodes may be arranged in closely spaced pairs. The energy generator may deliver mapping energy to each electrode in each pair individually to map tissue and may deliver ablation energy to the electrodes in each pair together, such that each pair is treated like a single electrode, to deliver ablation energy, such as bipolar ablation energy between adjacent pairs. One system includes at least one concave electrode, the configuration of which concentrates the energy and drives it deeper into the tissue. One system includes neutral electrodes between active electrodes, the energy generator selectively coupling the neutral electrodes to alter the ablation pattern.
