Researches from the institute of pathology of blood circulation of E. N. Meshalkin together with the Institute of theoretical and applied mechanics (ITPM) of S. A. Khristianovich developed an implant for pumping of blood from one area of heart in another which in the long term can replace donor heart, the director of NNIIPK of E. N. Meshalkin Alexander Karaskov reported on Tuesday.

"The new decision which will be more natural to an organism is supposed. Our analog will allow to minimize such terrible complications as thromboembolism which present on all devices both American, and European today that leads to very high percent of a lethality. This device will be able to replace donor heart almost completely", - the academician told.

According to his data, the device will be twice easier import analog (150 g instead of 300 g). Its task is to pump over blood with a speed up to 7 liters a minute. As it is reported by the official publication of the Siberian Branch of the Russian Academy of Science "Science in Siberia", the device will represent the improved analog of the device constructed by the American mechanics from NASA and realized in Germany.

The small motor which is pumping over blood is sewed in a body of the person, directly under heart. The wire to which the accumulators and other devices necessary for operation of the pump are connected is brought out of a stomach. This device was created for the people having heart failure. It is necessary to the patients expecting a heart transplantation, whom such operation can’t be made because of the age or recovery stage - so far heart doesn't cope with loading.

According to the academician of the Siberian Branch of the Russian Academy of Science Vasily Fomin, such pump costs about 250 thousand euro today. The scientific research institute of pathology of blood circulation of E. N. Meshalkin regularly buys it for the patients.

The new device, according to Karaskov won't be more expensive than the American analog. "It is still impossible to speak about its cost today, but it is precisely possible to tell that the model won't be more expensive than what are today", - he told.

The Siberian scientists received a grant of the Russian fund of basic researches - 1,5 million rubles for their work. Scientists plan to assemble the pump in 2015, to conduct researches on a thrombosis and to look at hydrodynamics during the following year, and tests on pigs or bulls will be possible in 2017.
