MIET scientists extended the life of the "artificial heart"

MIET scientists carried out a research and developed a mathematical model that helps to increase the efficiency of circulatory assist devices. According to the authors, their development allows to personalize devices for the patient's body, which will help increase the battery life.

An "artificial heart," or circulatory assist device (CAD), helps to move blood from the left ventricle of the heart to the aorta. First of all, CAD systems are necessary for patients with heart failure, whose heart is not able to pump the entire volume of incoming blood.

The researchers created a universal mathematical model that allows to personalize the parameters of CAD devices. The authors noted that their approach would increase the energy efficiency of such systems by about 20 percent. The mathematical model of the cardiovascular system is specialized software for modeling the interactions of implantable medical devices with the patient's cardiovascular system.

The mathematical model makes it possible to study the processes occurring under different operating modes of the pump. So the developers will be able to more find efficient technical solutions that can increase the efficiency of the system and increase its battery life.

The scientists plan to expand the model to describe not only axial, but also centrifugal circulatory assist pumps.
