Abstract
A method of ablating tissue includes positioning a treatment device proximate to a target tissue area. The treatment device has an expandable treatment element. The expandable treatment element is inflated with a refrigerant during an inflation phase such that at least a portion of the expandable treatment element is in contact with the target tissue area. A first pressure measurement of the inflated expandable treatment element is recorded and compared to a predetermined pressure threshold. The refrigerant is circulated within the expandable treatment element during an ablation phase to reduce a temperature of the target tissue area to a temperature sufficient to cryoablate the target tissue area. A second pressure measurement of the expandable treatment element is recorded during the ablation phase and compared to the predetermined pressure threshold.
