Abstract
A lesion characterization process is disclosed. According to one aspect, a method includes obtaining measurements of at least one of an impedance magnitude, impedance phase, a temperature, and electrical properties of tissue of the lesion. The method further includes determining at least one lesion property including at least one of a depth of the lesion, percent transmurality of the lesion, lesion surface area and lesion volume based on at least one of the obtained measurements.
Claims24
A method comprising:
- obtaining measurements of a lesion, the measurements comprising a temperature and at least one of an impedance magnitude, impedance phase, and electrical properties of tissue of the lesion;
- performing a statistical analysis of the obtained measurements, wherein the statistical analysis does not include a force measurement;
- determining at least one lesion property including at least one of a depth of the lesion, percent transmurality of the lesion, lesion surface area and lesion volume based at least in part on the statistical analysis of the obtained measurements;
- and
- outputting the at least one lesion property.
A lesion characterization system for characterizing a lesion based on a plurality of measurements, the system comprising:
- processing circuitry configured to:
- obtain measurements of at least one of an impedance magnitude, impedance phase, a temperature, and electrical properties of tissue of the lesion;
- and
- perform a statistical analysis of the obtained measurements, wherein the statistical analysis does not include a force measurement;
- determine at least one lesion property including at least one of a depth of the lesion, percent transmurality of the lesion, lesion surface area, lesion volume, and lesion contiguity based at least in part on the statistical analysis of the obtained measurements;
- and
- output the at least one lesion property.
