1. A device, comprising:

  • a catheter;

    an inflatable and/or expandable body coupled to the catheter;

    an electronic circuit disposed on the inflatable and/or expandable body, the electronic circuit comprising a plurality of components that accommodate expanding of the inflatable and/or expandable body, the plurality of components comprising;

    a plurality of electrodes, at least one electrode of the plurality of electrodes being a radiofrequency electrode configured to deliver a radiofrequency energy to a tissue proximate to the radiofrequency electrode; and

    a plurality of stretchable interconnects disposed on the inflatable and/or expandable body, wherein the plurality of stretchable interconnects electrically couples at least one of the plurality of electrodes to an external circuit;

    at least one flow sensor coupled to the catheter;

    at least one component coupled to the catheter and configured to perform an ablation procedure on a portion of a tissue proximate to the catheter; and

    an assessment module coupled to the at least one flow sensor and configured to receive data indicative of at least one flow measurement from the at least one flow sensor and provide an indication of the efficacy of the ablation procedure based on the data indicative of at least one flow measurement.
