TOMSK, Nov 8 – RIA Tomsk. Scientists of the Tomsk Scientific Research Institute of Cardiology and Tomsk Polytechnic University (TPU) got the patent of the USA and the European Union for special nanomaterial for coronary stents which prevents growth of therosclerotic plaques in arteries, it is reported on the website of the institute on Wednesday.
Earlier it was reported that scientists of the Tomsk Scientific Research Institute of Cardiology developed the coronary stents destroying atherosclerotic plaques in arteries. These deposits of cholesterin are dangerous that thrombus capable to lead to infarct or stroke are formed of them. The stent represents the spring which is holding apart walls of vessels. It is covered with biodegradable polymer with including of nanomaterial which was invented by TPU scientists.
With reference to professor of Scientific Research Institute of Cardiology Shamil Akhmedov it is explained that scientists had to find the nanomaterial capable to get into structure of atherosclerotic plaque and to change its properties. For this purpose the experiment was made together with the scientists of department of organic chemistry of TPU.
"(It) showed that the developed carbon nanocomposite... authentically reduces concentration of lipids in plasma. This new agent gained the international recognition in the form of the patent of the USA and the European Union. Now it is the first international patent in the history of the Scientific Research Institute of Cardiology, and the foundation is laid for this process", – it is said in the statement.
It is noted that the stent covered with this nanocomposite will allow not only to restore permeability of arteries, but also to prevent further growth of plaque, thereby minimizing risks of repeated narrowing of coronary artery.It is added that the new stent is much cheaper than the imported analog and it can be used already in the near future. But it is necessary to study toxicity of the developed nanocomposite for this purpose. The application for receiving a grant of the Russian Science Foundation together with the German partners which will be devoted to this subject is now being prepared.
