The European Patent Organization granted a patent to professor Albinas Stankus and dr. Žydrūnas Lukošius of Klaipėda University for their invention Device and System for Measuring the Blood Pressure and Augmentation Index of the Carotid Artery.

The newly patented invention is a medical device to be used by researchers in the areas of cardiology, neurology, and the circulatory system. Its specific purpose is to measure blood pressure and augmentation index in the carotid artery.

Compared to other devices with a similar function, its advantages are obvious. The most important thing is the possibility to see more accurate blood pressure close to the aortic arch, the most informative pressure of blood that is expelled directly from the heart. With this device, it is also possible to measure the diameter of the artery on a mechanical principle. That allows one to see even clogged arteries, which until now could only be done with complex, costly tests.

The innovative device consists of a strap-on neck ring on which a computer-controlled stepper motor is mounted, connected to a reciprocating piston. At the end of the piston is a force sensor for measuring the pressure at the carotid artery and its change over time.

Although the measuring device and system described in the invention are particularly suitable for measuring blood pressure in the carotid artery, this system can also be applied to measuring blood pressure in any part of the human body to which the device can be immovably fixed.

The process of developing and patenting the invention took 7 years, but, according to dr. Žydrūnas Lukošius, neither he nor his co-authors regret it.

“I would like things to happen faster, however, genuine science never happens quickly. There are many different stages to go through. The journey of our patent lasted up to 3 to 4 years, although we produced the device over the period of 2 to3 years,” said dr. Lukošius.

The innovation is currently in the prototype stage. In the future, it is expected to attract the interest of investors who, seeing the potential of the device, could develop the technology to the final product and apply it in medical institutions in Lithuania or abroad.
