1. An ablation device for treatment of tissue comprising:

  • an ablation structure comprising three or more bipolar electrode zones, each electrode zone comprising an in-zone channel pair comprising a positive channel and a negative channel,wherein the ablation structure is configured such that, for any adjacent electrode zone pair comprising one electrode zone and another electrode zone adjacent to the one electrode zone, the positive channel of the one electrode zone is electrically distinct from the positive channel of the other electrode zone, and the negative channel of the one electrode zone is electrically distinct from the negative channel of the other electrode zone; and

    wherein the ablation structure comprises a total number of electrically distinct channels that is less than twice a total number of the three or more bipolar electrode zones.
