The system (100) may include a support shaft (115), an expansion member (120) coupled with a distal portion (150) of the support shaft (115), and an ablation structure (160) wrapped around the expansion member (120) less than a circumference of the expansion member (120) configured to engage the body lumens with varying sizes. The ablation structure (160) may include multiple separately wired or separately controlled longitudinal electrodes (169) , longitudinal electrode zones (161, 162), or both, such that each longitudinal electrode (169) or longitudinal electrode zone (161, 162) may be selectively enabled or selectively disabled. The expansion member (120) may include a single highly-compliant balloon, a single non-compliant balloon (1501), multiple non-compliant balloons (1501), or a multi-chambered (1504, 1506) non-compliant balloon (1501).1/19 100 120 15016 170 151 115 140 142 146 165 145 175 105 FIG.A
