A device, system, and method for treating an area of tissue and evaluating lesion formation and quality. The system may include a medical device having a plurality of mapping electrodes on a treatment element, the plurality of mapping electrodes being configured to record from the area of tissue at least one of unipolar impedance measurements, bipolar impedance measurements, local electrical activity, and pace threshold measurements before, during, and after circulation of the cryogenic fluid within the treatment element. These measurements may be transmitted to a control unit having processing circuitry configured to compare pre-treatment measurements, in-treatment measurements, and/or post-treatment measurements to each other and/or to threshold values to determine occlusion and/or lesion quality, such as lesion transmurality.

A device for determining muscle condition of a region of tissue. The device comprises an electrical impedance myography (EIM) portable probe bearing an electrode array. The electrode array comprises excitation electrodes used to apply multi-frequency electrical signals to the region of tissue and pickup electrodes that are used to collect electrical signals resulting from the application of the multi-frequency electrical signals to the region of tissue. To improve accuracy and reproducibility of EIM measurements, the electrode array is reconfigurable to select different subsets of excitation and pickup electrodes so that the electrodes are oriented differently with respect to muscle fibers. Additional devices may be associated with the EIM probe to measure such parameters as temperature, moisture content of the region, quality of contact of electrodes of the electrode array with a surface of the region and pressure with which the EIM probe is applied to the region. The EIM measurements may be adjusted based on these parameters. Also, ultrasound and electrical impedance tomography measurements may supplement the EIM measurements for more complete analysis of the muscle condition.
