Unique artificial blood vessels developed in Russia
New technology to create artificial blood vessels that will make the treatment of acute thrombosis is much more accessible, has been developed by scientists of Tomsk Polytechnic University (TPU). According to the researchers, their proposed method is more efficient and better counterparts, and almost twice cheaper. The results were published in the journal Applied Surface Science.
Artificial vessels (grafts) are popular today in the treatment of acute thrombosis. In case to restore the functionality of the vessel medically or surgically is not possible, the affected area is removed and replaced with artificial, made of polycaprolactone or other biocompatible material.
“The main advantage of our grafts in that their outer layer is well wetted by water, so that they take root easily in the body, while the inner layer is not wetted on the contrary, providing optimum blood flow,” – said researcher of the laboratory “Plasma hybrid system”, TPU Eugene Bilbasov.
TPU scientists first proposed to use to create artificial blood vessels treatment method polycaprolactone in the plasma of the magnetron discharge. According to the authors, it simultaneously provides two key characteristics of grafts: a qualitative integration of the material with the tissues of the patient and high integrity.
To improve the survival rate of implanted grafts is now used extremely complex processing and expensive drugs. However, according to scientists, as a result of mechanical and functional characteristics of such vessels still leave much to be desired. The development of TPU, as noted by the authors, devoid of these shortcomings.
Further, a research team jointly with the specialists of the Tomsk Institute of cardiology intends to test the medical-biological properties of the developed grafts in living tissues.
