Abstract: A cardiac simulation method includes storing, in a memory, a measured electrophysiological (EP) map of at least part of wall tissue of a heart of a patient. Based on the stored EP map, simulated electrical activity in response to computer-simulated pacing, which simulates actual electrical activity that would occur across the wall tissue of the heart of the patient in response to actual pacing, is calculated in a processor. Based on the simulated electrical activity calculated in the processor, one or more candidate locations on the wall tissue of the heart at which arrhythmia is suspected of originating are identified and indicated to a user.

Abstract: A method for treatment evaluation includes applying energy through a probe to ablate tissue at a plurality of sites in an organ in a body of a patient, thereby creating lesions in the tissue including at least first and second lesions at respective first and second, mutually-adjacent sites. Location coordinates and respective treatment parameters are recorded at each of the sites with respect to the applied energy. Based on the recorded treatment parameters, respective measures of size of the lesions are computed, including at least respective first and second measures of the first and second lesions. An indication of contiguity between at least the first and second lesions is generated responsively to the first and second measures and to a distance between the location coordinates of the first and second sites.

Abstract: A medical analysis system, includes at least one catheter to be inserted into a body-part having a tissue surface, and comprising sensing electrodes to contact and receive electrical signals from the tissue surface, and processing circuitry to receive unipolar signals from individual ones of the plurality of the sensing electrodes, compute a combined far-field and mid-field signal based on summing and filtering ones of the received unipolar signals received from at least a pair of sensing electrodes disposed around a point of interest, compute a far-field signal as a weighted average of the received unipolar signals, weighted according to respective distances of the sensing electrodes from the point of interest, and compute and output a mid-field signal, representative of electrical activity below the tissue surface at the point of interest, based on subtracting the computed far-field signal from the computed combined far-field and mid-field signal.

Abstract: A tool positioning system for use in a medical procedure is provided which includes a medical tool configured to be navigated to a target tool location within a portion of an organ of a patient. The medical tool includes a sheath having a tube defined by a sheath wall, the sheath extending a length in a proximal-distal direction and an inflatable balloon coupled to the sheath and configured to move along the length of the sheath in the proximal-distal direction. When the inflatable balloon is inflated at a target balloon location along the length of the sheath, the inflated balloon is fixed at the target balloon location. The tool positioning system also includes memory configured to store location of the tool in a three dimensional (3D) space and at least one processor configured to generate mapping information for displaying locations of the tool in the 3D space.

Abstract: 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 Pi, the corresponding location data is processed to respectively produce an image Ii reflecting the position of the catheter at a time Ti. Each image Ii is successively displayed at a time equal to Ti+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.

Abstract: A method is described herein. The method is implemented by an optimization engine executed by a processor. The optimization engine receives data that includes performance metrics of mapping and ablation procedures. In turn, the optimization generates procedure expected outcomes for the mapping and ablation procedures based on the data and success predictions for a current ablation procedure utilizing the procedure expected outcomes. The optimization engine, also, outputs an ablation recommendation based on the success predictions.

Abstract: 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.

Abstract: A method of occlusion detection is disclosed. The method comprises the steps of positioning a medical tool coupled to a distal portion of a distal end of a delivery catheter at a target cavity within a patient. The medical tool includes an expandable balloon, and at least one sensor. The expandable balloon is expanded when positioned at the target cavity. The expandable balloon includes a membrane formed of a plurality of irrigation pores. Fluid is introduced into the target cavity either by injection or through the pores, or both. Using a sensor, a characteristic of blood is detected with the target cavity. The characteristic of blood is processed to determine the presence or absence of an occlusion within the cavity.

Abstract: The presently disclosed subject matter includes computer methods and computer systems that enable to select and provide a suitable treatment for AF patients that increases the likelihood of long-term amelioration of AF conditions, and thereby enhances treatment of AF patients. The disclosure provides methods and systems for analysis of the condition of AF patients and the tailoring of personalized treatment regimens based on various AF features obtained from the patients, and the determination of a treatment selected from at least PVI only and PVI plus. To overcome technical difficulties resulting from scarcity of data a machine learning model that is trained using physician recommendation rather than observed treatment outcome is disclosed.
