Publication number: 20240148311Abstract: An example method includes storing reconstructed electrophysiological data sets for at least two baseline time intervals and at least one modulation time interval. The electrophysiological data sets are representative of electrophysiological signals reconstructed at locations across a respective surface of interest within a patient's body based on non-invasively measured electrophysiological signals for respective time intervals. The modulation time interval can overlap with modulating an arrhythmia or arrhythmogenic activity. The method can also include computing dominant frequency maps from the electrophysiological signals reconstructed for at least two baseline data sets and the at least one modulation data set. The method can also include analyzing the dominant frequency maps to determine an indication of dominant frequency stability across at least a portion of the surface of interest.Type: ApplicationFiled: October 24, 2023Publication date: May 9, 2024Inventors: David Calvo CUERVO, Omer BERENFELD

Publication number: 20240057919Abstract: Techniques are provided that identify and localize on to reentrant and ectopic patterns of electrical activation in the heart wall. These patterns may correspond to atrial fibrillation, ventricular fibrillation, or other heart arrhythmia conditions. The techniques detect these patterns of electrical activity using a multi-lead an intra-cavitary catheter that, along with a controller, is able to track, over a multi-dimensional cubic space, reentrant activity and identify filaments in the heart cavity. The intra-cavitary catheter includes multiple conducting poles positioned in a configuration relative to each other and functioning as either or both sensing and active poles for measuring electrical pathways in the heart wall and over the multi-dimensional space.Type: ApplicationFiled: November 1, 2023Publication date: February 22, 2024Inventor: Omer Berenfeld

Publication number: 20170251978Abstract: The present invention relates to a catheter and method for detecting electrical activity in an organ. The catheter comprises: a proximal end with connection means for connecting to a signal processing system and a distal end for being inserted into a patient's organ, at least 3 arms extending from the distal end, each arm comprising at least one electrode. The catheter further comprises a central electrode at the distal end of the catheter. The method comprises: inserting a multi-electrode catheter into a patient's organ; obtaining and conditioning a positioning signal for positioning the electrodes; obtaining causal information about the current location; processing and summarizing the causal information obtained together with causal information about previous locations; visually presenting a recurrence plot of all the causal information obtained; and then moving the catheter to a new location and repeating the method until obtaining a complete recurrence plot.Type: ApplicationFiled: September 9, 2015Publication date: September 7, 2017Inventors: Miguel RODRIGO BORT, Maria de la Salud GUILLEM SANCHEZ, Batiste Andreu MARTINEZ CLIMENT, Felipe ATIENZA FERNANDEZ, Omer BERENFELD

Patent number: 9037223Abstract: An atrial fibrillation classification system collects celectrocardiogram signals and converts them to a frequency, time, or phase domain representation for analysis. An evaluation stage extracts energy density profile over a range of frequencies, time intervals, or phases, which is then summed and normalized to form dispersion metrics. The system then analyzes the dispersion metrics, in their respective domains, to determine whether a patient is experiencing an arrhythmia and then to classify the type of arrhythmia being experienced.Type: GrantFiled: January 10, 2013Date of Patent: May 19, 2015Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Hakan Oral, Omer Berenfeld, Grant Kruger

Patent number: 7117030Abstract: A method and computer program product comprising an algorithm adapted to execute a method of identifying the spatial coordinates of a sustaining source of fibrillatory activity in a heart by computing a set of point-dependent dominant frequencies and a set of point-dependent regularity indices for a set of products of point-dependent unipolar discrete power spectra and point-dependent bipolar discrete power spectra, derived by spectral analyses of corresponding unipolar and bipolar cardiac depolarization signals simultaneously acquired from a set of points of the heart. A maximum dominant frequency is selected whose associated coordinates identify the point of the sustaining source of fibrillatory activity. The magnitude of the regularity index is interpreted to verify the identification of the spatial coordinates of the sustaining source of fibrillatory activity. When indicated, surgical intervention is directed to the spatial coordinates of the sustaining source of fibrillatory activity.Type: GrantFiled: December 2, 2004Date of Patent: October 3, 2006Assignee: The Research Foundation of State University of New YorkInventors: Omer Berenfeld, Jose Jalife, Ravi Vaidyanathan
