摘要：
In some implementations, a method of ablating body tissue includes (a) locating an inflatable balloon portion of a cryotherapy balloon catheter at a treatment site internal to a patients body, and inflating the inflatable balloon portion (b) employing electrodes that are disposed on an expandable surface of the inflatable balloon portion to electrically characterize body tissue at the treatment site (c) ablating the body tissue by supplying a cryotherapy agent to the inflatable balloon portion to cool the body tissue to a therapeutic temperature (d) employing the electrodes to determine whether the ablating caused desired electrical changes in the body tissue and (e) repeating (c) and (d) when it is determined that the ablating did not cause the desired electrical changes.
