Patent number: 11464437Abstract: 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.Type: GrantFiled: February 18, 2020Date of Patent: October 11, 2022Assignee: Biosense Webster (Israel) Ltd.Inventors: Shiran Eliyahu, Vladimir Rubinstein, Limor Provizor, Elias Shamilov, Herman-Eyal Lencovski, Inbal Dubiner

Patent number: 10898093Abstract: Apparatus for assessing scarring of cardiac tissue, consisting of a probe and a processor. The probe has one or more electrodes, which are configured to contact the tissue at a plurality of positions and to sense respective voltages in the tissue at the positions. The processor receives the respective voltages, and computes a triangular mesh that is representative of a surface of the tissue and that consists of multiple triangles having vertices corresponding to the positions contacted by the one or more electrodes. The processor calculates respective scar areas within the triangles by comparing the respective voltages sensed at the positions corresponding to the vertices to a predefined range of the voltages that is associated with scarring, and computes a sum of the respective areas. The processor compares the sum to a total area of the triangles so as to assess a degree of the scarring of the tissue.Type: GrantFiled: December 25, 2018Date of Patent: January 26, 2021Assignee: Biosense Webster (Israel) Ltd.Inventors: Michael Timofeyev, Tal Haim Bar-on, Gal Hayam, Inbal Dubiner
