摘要:
Methods, systems, and devices for providing treatment to a tissue in body lumens are described. The system may include a support shaft, an expansion member coupled with a distal portion of the support shaft, and an ablation structure wrapped around the expansion member less than a circumference of the expansion member configured to engage the body lumens with varying sizes. The ablation structure may include multiple separately wired or separately controlled longitudinal electrodes, longitudinal electrode zones, or both, such that each longitudinal electrode or longitudinal electrode zone may be selectively enabled or selectively disabled. The expansion member may include a single highly-compliant balloon, a single non-compliant balloon, multiple non-compliant balloons, or a multi-chambered non-compliant balloon.
