What changed

The United States Patent and Trademark Office (USPTO) has issued patent US12582321B2 to CARDIOSTORY INC. for a method, device, and system for assessing cardiac diastolic function. The patent, filed on May 20, 2019, and granted on March 24, 2026, describes a non-invasive technique that acquires thoracic body surface vibration information, preprocesses it to derive hemodynamics-related information, determines key parameters, and generates an indicating parameter to assess cardiac diastolic function.

This patent grant signifies the protection of intellectual property related to cardiac monitoring technology. While not a regulatory mandate for healthcare providers, it may influence the development and commercialization of diagnostic tools in cardiology. Companies developing or utilizing similar technologies should be aware of this patent to avoid potential infringement. No immediate compliance actions are required for healthcare providers based solely on this patent grant.

Abstract

A cardiac diastolic function assessment method, for use in the field of cardiac monitoring. The method comprises: noninvasively acquiring vibration information of the thoracic body surface of a subject; preprocessing the vibration information to generate hemodynamics-related information; determining a first parameter and a second parameter on the basis of the hemodynamics-related information; generating an indicating parameter on the basis of the first parameter and of the second parameter, and assessing the cardiac diastolic function of the subject on the basis of the indicating parameter.
