The present disclosure provides systems, apparatuses and methods that provide probe-cavity location and motion data based on probe location and respiration data.

Probe-cavity motion modeling

A method includes assigning, to first voxels in a model of tissue of a chamber of a heart, respective first values of a parameter at respective locations on the tissue, the first voxels representing the locations, respectively. Some of the locations are on an endocardial surface of the tissue, and others of the locations are on an epicardial surface of the tissue. The method further includes assigning respective second values to second voxels in the model, a subset of which represent a portion of the tissue between the endocardial surface and the epicardial surface, by interpolating the first values. Other embodiments are also described.

Volumetric LAT map

A system includes a processor and a display. The processor is configured to: (i) receive a first dataset corresponding to a first property of an organ of a patient, and a second dataset corresponding to a second property of the organ, (ii) assign a first visual attribute to the first property and a second visual attribute to the second property, and (iii) produce a map of the organ including an overlay of the first and second visual attributes. The display is configured to display the map.

Visualizing multiple parameters overlaid on an anatomical map

A method includes receiving or generating a volume map of at least a portion of a cavity of an organ of a body including a plurality of mapped locations, and a point cloud of locations in the cavity marked for treatment. The volume map is updated by removing a portion of the mapped locations, so that the locations marked for treatment fall on a surface of the volume map. Using the updated volume map, a map of at least a portion of the cavity is generated, the map including the locations marked for treatment. The map is displayed to user.

Automatic mesh reshaping of an anatomical map to expose internal points of interest

A system includes a display and a processor. The processor is configured to: (i) receive a dataset including multiple data points, each data point corresponding to one or more properties of an organ of a patient, (ii) produce, based on a clustering criterion, at least a cluster including two or more of the data points, and (iii) produce and present on the display, a map of the organ and at least an object indicative of the cluster. In response to selection of the object by a user, the processor is configured to produce and present on the display, a two-dimensional (2D) table including the one or more properties of each of the clustered data points.

Multi-layered visualization of data points over heart map

A system and method for Brugada syndrome epicardial ablation comprising preparing an endocardial duration map; preparing a baseline epicardial duration map comprising at least one or more areas of delimination; and when some of the areas of delimination are greater than 200 ms, performing epicardial ablation of the areas of delimination greater than 200 ms. The method may further comprise preparing an updated epicardial duration map after performing epicardial ablation, and determining whether or not a BrS pattern appears in the updated epicardial duration map; and when the BrS pattern appears, performing epicardial ablation. The method may further comprise preparing an updated epicardial duration map after performing epicardial ablation, and determining whether or not an abnormal EGM exists in the updated epicardial duration map; and when the abnormal EGM exists, performing epicardial ablation. The method may further comprise preparing an updated epicardial map comprising maintaining anatomical volume data and adding electroanatomical data.

Analyzing and mapping ECG signals and determining ablation points to eliminate Brugada syndrome

Methods, apparatus, and systems for medical procedures are disclosed herein and include sensing a plurality of tissue electrical potentials at an organ area of an organ, by one or more electrodes on a catheter, determining a number of peak electrical potentials from the plurality of first tissue electrical potentials such that the a peak electrical potential exceeds a potential threshold, determining a first visual characteristic based on the number of peak electrical potential and displaying a rendering of the organ comprising the organ area such that the rendering of the first organ area comprises the first visual characteristic.

Enhanced visualization of organ electrical activity

A probe having a contact force sensor is inserted into a cardiac chamber and an image of the blood pool is generated. A portion of the blood pool is removed from the image to retain a remaining portion of the blood pool. A determination is made that the distal segment of the probe is within the remaining portion of the blood pool, and responsively to the determination the contact force sensor is manually zeroed.

Assistive manual zeroing visualization

A medical display processing device and a method of reusing data includes acquiring, over time via electrodes, electrical signals each acquired via one of the electrodes and indicating electrical activity at a location of a portion of patient anatomy in a 3D space. Electrical signal data, corresponding to the electrical signals, is filtered according to first filter parameter settings and first mapping information is generated for displaying a map of the portion of patient anatomy and the filtered electrical signal data. An indication of a region of the portion of patient anatomy on the map is received and second mapping information is generated for displaying, at the region on the map, a portion of the electrical signal data previously filtered from display.

Data reuse for filling in missing data points

Methods, apparatus, and systems for medical procedures are disclosed herein and include receiving a first electrical activity at a first time for a plurality of points on an intrabody surface. A first cluster of points is identified from the plurality of points, based on the first electrical activity, the first cluster of points each exhibiting electrical activity above an activity threshold. A second electrical activity is received at a second time for the plurality of points on the intra-body surface. A second cluster of points is identified from the plurality of points, based on the second electrical activity. The first cluster of points and the second cluster of points are determined to be related based on a propagation threshold. A first visual indication for a first propagation route is provided from the first cluster of points to the second cluster of points.

Visual route indication for activation clusters

Methods, apparatus, and systems are provided for facilitating the navigation of a catheter between first and second locations within a subject based on display of serial images corresponding to positions of the catheter at successive incremental times. Image production includes sensing catheter positions to produce location data for each time increment. For each position P, the corresponding location data is processed to respectively produce an image Ireflecting the position of the catheter at a time T. Each image Iis successively displayed at a time equal to T+d, where d is an image processing visualization delay. Upon a condition that the catheter is displaced to a selected interim location between the first and second locations, the processing of the location data is switched from being performed by a first process associated with a first visualization delay to a second process associated with a second different visualization delay.

Enhanced catheter navigation methods and apparatus

Image processing is carried out by accepting an array of voxels that include data representing a physical property of a 3-dimensional object, segmenting the array of voxels into a plurality of regional subarrays of voxels that respectively satisfy predetermined criteria, transforming the subarrays into respective triangular meshes, the meshes having triangles that surround the subarrays and intercept the outer voxels of the subarrays, and rendering the triangular meshes on a display
