Sensors for intra vascular diagnostics

2016: Development of sensors for intra vascular diagnostics

In July, 2016 it became known that scientific scientific research institutes of the semiconductor devices (SD) and scientific research institute of cardiology in Tomsk develop microsensors for intra vascular diagnostics which can replace expensive foreign analogs.

Creation of two sensors on the basis of microelectromechanical and LED technologies is planned. One of devices will measure pressure in blood vessels, and another will be used for an intra vascular optical tomography.

The optical pickup will show a vessel from within, providing observation of how the stent gets accustomed: if it grows endoteliy, so the risk of complications is minimum, and it is possible to adjust treatment — to reduce amount of drugs, the associate director of the Tomsk scientific research institute of cardiology Shamil Akhmedov notes.

In Russia microsensors are developed for intra vascular diagnostics

The developed microsensors for diagnostics and treatment of cardiovascular diseases, are silicon crystals with the built-in microelectronics with a diameter up to 1 mm. Thanks to the ultracompact sizes devices can be entered even into the narrowest vessels, including coronary, feeding heart.

Moving ahead on a vessel, the sensor will measure pressure before and after an atherosclerotic plaque. Thus, it is possible to estimate extent of narrowing of a vessel before introduction of the coronary stent, Akhmedov reported.

According to him, low-invasive intervention will not demand transaction and long recovery, in a day or two after carrying out a research of the patient it is possible to write out home. Microsensors are necessary for diagnostics of all range of cardiovascular diseases — from atherosclerosis to heart diseases — and can be used at treatment of both children, and adults.

Shamil Akhmedov noted that similar sensors are not manufactured in Russia, and foreign analogs can cost up to 300 thousand rubles.^[1]
