What changed

The USPTO published a patent application disclosing a method for identifying atrial fibrillation trigger sites using electrode signal correlation analysis. The system determines composite correlation scores for selected spatial locations in the heart based on correlations between signals from a selected electrode positioned at that location and signals from other electrodes. The electro-anatomical map displays these scores to indicate suspected AF trigger locations. Assignee: Biosense Webster (Israel) Ltd.; Inventors: Haim Rodriguez, Matityahu Amit.

This publication is a routine patent application notice with no compliance requirements for third parties. Entities developing cardiac mapping or ablation technologies should review the disclosed correlation methodology for potential overlap with existing development programs. Patent publications do not create regulatory obligations but may inform freedom-to-operate analyses.

Abstract

A composite correlation score associated with a selected spatial location in the heart is determined based on a plurality of individual correlation values, each of which is based on a correlation between a signal associated with a selected electrode positioned at the selected spatial location and a signal associated with another one of the plurality of electrodes when the selected electrode is positioned at the selected spatial location. Composite correlation scores associated other selected spatial locations in the heart are determined the same way. An electro-anatomical map of the heart is displayed which depicts information representative of the composite correlation score determined for the selected spatial locations, including information indicating that a spatial location is a suspected trigger of AF.
