  • Patent number: 10285749
    Abstract: A method, system, and device for predicting lesion quality. Specifically, lesion quality may be predicted based on an assessment of pulmonary vein occlusion using saline injection and evaluation of temperature measurements recorded by a thermocouple located distal to the cryoballoon of the treatment device. The quality of the occlusion may be rated based on the time it takes the temperature recorded by the thermocouple to increase from approximately 2° C. to approximately 38° C., the rate of temperature change over a predetermined time period, and/or the rate of dissipation within the pulmonary vein of the saline with a volume of contrast medium. For example, the quality of the occlusion may be rated as being good, fair, or poor. This assessment may be quickly and easily communicated to an operator.
