1. a kind of for treating the ablating device of the tissue in different size of body lumen, comprising:

  • Support shaft;

    Expansion member, the expansion member couple with the distal part of the support shaft;

    Ablation structure, the ablation structure include multiple longitudinal electrode regions,Wherein;

    The ablation structure is less than wrapping up circumferentially around the expansion member for the expansion member;

    AndThe ablation structure and the expansion member are configured to engage at least part of the different size of body lumen;

    AndAt least part at least one longitudinal electrode region is configured to selectively activate or disable, at least partly baseTreatment is provided in the identification for the first area previously melted and the determination of second area to be ablated, described to be ablatedThe determination in two regions by being provided in the visual detector of expansion member, using related to one or more lumen circumferential direction measured valuesThe selecting module of the look-up table of connection uses impedance measurement and ratio of the probe sensor between first area and second areaRelatively carry out.
