US Patent Issued on April 21 for "Apparatus for providing indices of elasticity or stiffness of an artery" (Canadian Inventor)

ALEXANDRIA, Va., April 21 -- United States Patent no. 12,605,074, issued on April 21.

"Apparatus for providing indices of elasticity or stiffness of an artery" was invented by Trevor Tucker (Ottawa).

According to the abstract* released by the U.S. Patent & Trademark Office: "An apparatus for measuring stiffness of a blood vessel such as an artery acquires a flow velocity waveform which is used to determine Natural Resonant Frequency and Pulse Wave Velocity for an arterial location. Pulse Wave Velocity is an established index of arterial stiffness while Natural Resonant Frequency is an index of arterial stiffness. The apparatus includes a flow velocity waveform detecting unit, a flow velocity and timing data extraction unit, and natural re...
