Abstract: A method for performing a medical procedure, includes, coupling a probe to tissue in an organ of a patient. Ablation energy is applied to the tissue using the probe. A model of an evolution of steam pressure in the tissue, caused by the ablation energy, as a function of time is estimated. Based on the model, an occurrence time of a steam pop event caused by the steam pressure is predicted, and the predicted occurrence time of the steam pop event is indicated to an operator.

Abstract: A method includes positioning body-electrodes in galvanic contact with a body of a patient and positioning a mapping-tool, having a mapping-electrode, in a plurality of regions in the body. The method further includes tracking the mapping-tool at different positions in each of the regions using a location-measuring system, and for each region, generating a respective set of calibration-currents between the body-electrodes and the mapping-electrode at the different positions in the region. A respective relation is derived for each region between the respective set of the calibration-currents and the different positions, and is used in determining the location of an investigation-tool in response to the different respective relations and investigation-tool-currents.

Abstract: An apparatus includes an interface and a processor. The interface is configured for exchanging signals with: (i) a probe, which is inserted into a body of a patient and includes a flexible distal-end assembly, wherein the distal-end assembly comprises a magnetic position sensor and two or more intra-body electrodes, and, (ii) multiple body-surface electrodes attached externally to the body of the patient. The processor is configured to estimate, based on the signals exchanged with the probe, a spatial displacement of the magnetic sensor between consecutive measurements, and to estimate a position of the distal-end assembly in the body based on (i) the signals exchanged with the intra-body electrodes and the body-surface electrodes, (ii) a-priori known spatial relationships between two or more of the intra-body electrodes of the probe and (iii) the estimated spatial displacement of the magnetic sensor.
