PSA Cardiac Activation Detection Method and System
Summary
The USPTO granted Patent No. US12588856B2 to Biosense Webster (Israel) Ltd. covering methods for identifying and graphically indicating cardiac tissue locations exhibiting progressively slowing activation (PSA) based on cardiac signal analysis. The patent includes 14 claims and names eight inventors including Tal Haim Bar-On and Kumaraswamy Nanthakumar.
What changed
USPTO issued Patent US12588856B2 to Biosense Webster (Israel) Ltd. on March 31, 2026. The patent protects a method for detecting progressively slowing cardiac activation by receiving cardiac signals sensed via electrodes, identifying signal components from activations, annotating those components, calculating time differences between annotations and corresponding activations, and identifying tissue locations demonstrating PSA. An EP map is presented with graphical indication of PSA locations. The filing date was December 14, 2022, and the application number is 18080875.
Organizations developing cardiac mapping, EP mapping systems, or related diagnostic technologies should conduct freedom-to-operate analyses to assess whether their products may fall within the scope of the 14 claims. R&D teams designing electrode-based cardiac signal processing systems should review the annotated signal identification and time-difference calculation methodology to evaluate potential design-around options. Patent counsel should be consulted for validity opinions or licensing inquiries.
What to do next
- Conduct freedom-to-operate analysis for cardiac mapping products
- Review patent claims for design-around opportunities
- Consult patent counsel regarding licensing or validity

Abstract
A method includes receiving a cardiac signal that is sensed by electrodes at a location in a heart of a patient, the cardiac signal including signal components evoked by respective activations. The signal components in the cardiac signal are found and annotated. Respective time differences are calculated between the annotations and the corresponding activations. Based on the time differences, one or more cardiac tissue locations are identified, that demonstrate progressively slowing activation (PSA). An EP map of at least a portion of the heart is presented to a user, including providing a graphical indication of the one or more tissue locations that demonstrate the PSA.
