What changed

The United States Patent and Trademark Office (USPTO) has issued patent US12582320B2, titled 'Assessment of a vessel.' This patent, granted on March 24, 2026, covers a method for assessing a vessel by obtaining pressure measurements at two different locations, identifying leading and trailing characteristics from these measurements, and subsequently calculating a pressure ratio. The application was filed on July 7, 2020, under application number 16922269, with 11 claims.

This patent grant represents a new intellectual property right for a specific medical technology. While it does not impose direct regulatory obligations on companies, it may affect the competitive landscape for medical device manufacturers and pharmaceutical companies involved in diagnostic or surgical technologies related to vessel assessment. Companies operating in this space should be aware of this patent to ensure they do not infringe on the granted claims, particularly if developing similar assessment methods or devices.

Abstract

One method for assessing a vessel can include obtaining a set of first location pressure measurements at a first location in the vessel over a first time period and a set of second location pressure measurements at a second location in the vessel over the first time period. This method can further include identifying a first leading characteristic associated with one or more pressure measurements in the set of first location pressure measurements, a second leading characteristic associated with one or more pressure measurements in the set of second location pressure measurements, a first trailing characteristic associated with one or more pressure measurements in the set of first location pressure measurements, and a second trailing characteristic associated with one or more pressure measurements in the set of second location pressure measurements. And, this method can include calculating a pressure ratio using pressure measurements between the identified characteristics.
