  • Patent number: 10675086
    Abstract: A method and system for presenting information representative of lesion formation is provided. The system comprises an electronic control unit (ECU). The ECU is configured to acquire a value for an ablation description parameter and/or a position signal metric, wherein the value corresponds to a location in the tissue. The ECU is further configured to evaluate the value, assign it a visual indicator of a visualization scheme associated with the parameter/metric corresponding to the value, and generate a marker comprising the visual indicator such that the marker is indicative of the acquired value. The method comprises acquiring a value for the parameter/metric, and evaluating the value. The method further includes assigning a visual indicator of a visualization scheme associated with the parameter/metric corresponding to the value, and generating a marker comprising the visual indicator.

  • Patent number: 8700129
    Abstract: A medical device can be localized by providing at least three non-colinear localization elements (e.g., electrodes) thereon. Once placed in a non-ionizing localization field, three adjacent localization elements, at least one of which will typically be a spot electrode, may be selected, and the non-ionizing localization field may be used to measure their locations. A cylinder is defined to fit the measured locations of the selected localization elements. The cylinder is rotationally oriented using the measured location of a spot electrode. Location and rotational attitude information may be used to construct a three-dimensional representation of the medical device within the localization field. The electrodes may be provided on the medical device or on a sheath into which the medical device is inserted. The invention also provides systems and methods for identifying and calibrating deflection planes where the medical device and/or sheath are deflectable.
