Patent number: 12256982Abstract: A method for estimating a thickness of cardiac tissue undergoing ablation includes the steps of (a) applying a sequence of ablation pulses to a region of the cardiac tissue, so as to create a lesion, and (b) for a given ablation pulse in the sequence, an incremental depth added to the lesion due to the given ablation pulse is estimated. A cumulative depth of the lesion is estimated based on the cumulative depth prior to the given pulse, and on the incremental depth. An amplitude of an electrogram signal at the region is assessed after applying the given ablation pulse, and, if the amplitude exceeds a predefined threshold, an estimate of the thickness is set to be at least the cumulative depth.Type: GrantFiled: March 19, 2020Date of Patent: March 25, 2025Assignee: Biosense Webster (Israel) Ltd.Inventors: Assaf Govari, Andres Claudio Altmann
