摘要：
Methods, apparatuses, and systems are described for minimizing various leakage effects of multi-zone ablation devices. Apparatuses may include an ablation device for treatment of tissue including an ablation structure with a plurality of bipolar electrode zones. Each of the zones may include an in-zone channel pair comprising a positive channel and a negative channel. The ablation structure may be configured such that, for any adjacent electrode zone pair comprising a first electrode zone and a second electrode zone adjacent to the first electrode zone, the positive channel of the first electrode zone is electrically distinct from the positive channel of the second electrode zone, and the negative channel of the first electrode zone is electrically distinct from the negative channel of the second electrode zone. Moreover, the ablation structure may be arranged such that a total number of electrically distinct channels that is less than twice a total number of the plurality of electrode zones.
