  • Patent number: 12023091
    Abstract: Devices and methods for tissue lesion assessment and/or creation based on dielectric properties are disclosed. In some embodiments, one or more probing frequencies are delivered via electrodes including an electrode in proximity to a tissue (for example, myocardial tissue). Measured dielectric properties (such as impedance properties), optionally together with other known and/or estimated tissue characteristics, are used to determine the lesion state of the tissue. In some embodiments, a developing lesion state is monitored during treatment formation of a lesion (for example, ablation of heart tissue to alter electrical transmission characteristics).

  • Publication number: 20240189024
    Abstract: A mechanism for providing a trigger signal that is usable to control the collection of electrode calibration data from a catheter. The trigger signal is responsive to a predictive indicator that indicates a likelihood that the catheter is in contact with the anatomical structure, and in particular examples, that the catheter is completely immersed in blood. The predictive indicator is generated using a ratio between two measurements that change responsive to touching the anatomical structure.

  • Publication number: 20240180623
    Abstract: Devices, systems, and methods for guiding a balloon therapy procedure by generating and outputting a visualization of the volumetric position of a balloon within an anatomical cavity are provided. For example, in one embodiment, a processor circuit is configured to control a plurality of electrodes to detect an electromagnetic field within the anatomical cavity, and determine, based on the detected electromagnetic field and a geometrical parameter associated with the balloon (e.g., size, shape of the balloon), a location of the balloon within the anatomical cavity. The processor circuit outputs a signal representation of a visualization of the balloon to guide placement of the therapeutic balloon. In some embodiments, the visualization is output to a display with a map of the anatomical cavity. The visualization may be updated based on detected movement of the balloon to provide a real time view of the location of the balloon within the anatomical cavity.

  • Patent number: 11854217
    Abstract: Systems, devices, and methods for co-registering electro-anatomical images are provided. In one embodiment of the present disclosure, treatment locations are displayed to the physician on an image of the remodeled heart by co-registering first and second electro-anatomical images based on: (1) a first electro-anatomical image of an anatomy, (2) treatment location data indicating treatment locations with respect to the first electro-anatomical image, (3) a second electro-anatomical image of the anatomy after the anatomy has remodeled, and (4) a non-rigid transformation that transforms the first electro-anatomical image to the second electro-anatomical image of the remodeled anatomy. The non-rigid transformation is applied to the treatment location data to map the treatment locations to the second electro-anatomical image of the remodeled anatomy.

  • Patent number: 11842456
    Abstract: Methods for creation and use (e.g., for navigation) of displays of flattened (e.g., curvature-straightened) 3-D reconstructions of tissue surfaces, optionally including reconstructions of the interior surfaces of hollow organs. In some embodiments, data comprising a 3-D representation of a tissue surface (for example an interior heart chamber surface) are subject to a geometrical transformation allowing the tissue surface to be presented substantially within a single view of a flattened reconstruction. In some embodiments, a catheter probe in use near the tissue surface is shown in positions that correspond to positions in 3-D space sufficiently to permit navigation; e.g., the probe is shown in flattened reconstruction views nearby view regions corresponding to regions it actually approaches. In some embodiments, automatic and/or easily triggered manual view switching between flattened reconstruction and source reconstruction views is implemented.

  • Patent number: 11806126
    Abstract: Methods and systems for position determination of an intrabody probe, targets of an intrabody probe, and or actions to be performed using an intrabody probe are described. In some embodiments, an anatomy being navigated and/or mapped is described by a rule-based schema relating different anatomically identified structures to one another according to their ability to help identify and/or locate one another. Additionally, in some embodiments, data recorded from the intrabody probe is processed according to schema rules in order to provide anatomical identification of the anatomical region which the intrabody probe is sampling, optionally without performing detailed mapping, and/or prior to the availability of detailed mapping of anatomical geometry.

  • Publication number: 20230338091
    Abstract: A mechanism for generating two or more contact indicators indicating whether an inflatable balloon of a balloon therapy catheter is in contact with the boundaries of an anatomical cavity. The mechanism obtains an anatomical model of the anatomical cavity, determines a location of a balloon therapy catheter with respect to the anatomical cavity, and uses this information, together with one or more geometric properties of the inflatable balloon, to derive the two or more contact indicators.

  • Patent number: 11793571
    Abstract: In some embodiments, data sensed and/or operational parameters used during a catheterization procedure are used in the motion frame-rate updating and visual rendering of a simulated organ geometry. The organ geometry is rendered as a virtual material using a software environment (preferably a graphical game engine) which applies simulated optical laws to material appearance parameters affecting the virtual material's visual appearance, as part of simulating a scene comprising the simulated organ geometry, and optionally also comprising simulated views of a catheter probe used for sensing and/or treatment. Optionally, measurements of and/or effects on tissue by sensing and/or commanded probe-tissue interactions are converted into material appearance changes, allowing dynamic visual simulation of intra-body states and/or events based on optionally non-visual input data.

  • Patent number: 11793576
    Abstract: Systems and methods are described for planning of catheter ablation procedures, and in particular for planning of the placement of lesions and/or parameters used in ablation. In some embodiments, planning is based on thermal and/or dielectric simulation of lesions, individualized to the anatomy of the particular patient. Optionally, a plan comprises planning of a path along which an ablation lesion is to be formed, the ablation lesion optionally comprising one or more sub-lesions. The plan is optionally optimized for one or more criteria including, for example: minimization of path length, minimization of sub-lesion number, simplification of catheter maneuvering, avoidance of collateral damage to non-target tissue, access to the target dependent on anatomy shape and/or catheter mechanics, and/or features of the target anatomy such as tissue wall thickness and/or fiber direction.

  • Patent number: 11744515
    Abstract: Methods for estimating of the effectiveness of catheter ablation procedures to form lesions, and particular lesions which together form an ablation segment of an ablation line. Lesion effectiveness parameters are received, and effectiveness, optionally the joint effectiveness, of corresponding ablations (optionally planned, current, and/or already performed) is estimated. In some embodiments, estimating is based on use by computer circuitry of an estimator constructed based on observed associations between previously analyzed lesion effectiveness parameters, and observed lesion effectiveness. Additionally or alternatively, estimators may be constructed based on analytic functions. The estimator is used by application to the received lesion effectiveness parameters.
