Nikolay Devyatkov

Microwave thermotherapy Nikolay Devyatkov, together with Eduard Gelvic, Vladimir Mazohin and others developed the theoretical framework and create an apparatus of the microwave thermotherapy (hyperthermia) operating local electromagnetic hyperthermia of malignant neoplasms. At present, this direction is actively developed and theoretical developments Devyatkov and his colleagues are embodied in manufactured today in the company "Istok" installation: "Yachta-4M" for the local microwave thermotherapy of malignant neoplasms and diseases of the prostate "Yachta-5" for the general and local microwave thermotherapy of malignant neoplasms. and apparatus for recording the pH. Also he created the original versions of pH-probes with 3, 4 and 5 sensors, intraoperation, endoscopic, children's pH-probes for different age groups, dentistry and gynecology pH-probes, as well as equipment, recording pH with multisensor pH-probes. With the direct participation Devyatkov the NPC "Istok" were organized serial production of the first in the USSR pH-probes for gastrointestinal pH-metry. Method of complex study of the functional state of the stomach and duodenum, providing simultaneous measurement of pressure and acidity in different parts of the gastrointestinal tract and is called at that time "ionomanometry" has been applied in medical practice since 1974. Under the guidance of Devyatkov was made probe with 4 pH sensors, and 4 plastic manometric catheters.

This area of his research has its modern development in the devices for diagnostic gastroenterology: esophageal pH monitoring, esophageal motility study, electrogastroenterography and other, that has brandname "Gastroscan" in Russia and are the main products of Fryazino company ZAO NPP «Istok-Sistema».

Other areas Devyatkov and his colleagues performed a series of pioneering work in the field of medical thermography, were developed the therapy and surgical lasers, electrodes for coagulation endovascular veins, xenon feeds "Yakhont" for the treatment of otolaryngology, dental and gynecological diseases, and others.

Awards Devyatkov received the Stalin Prize (1949), the Lenin Prize (1965), the State Prize of the Russian Federation (2000) and the Hero of Socialist Labour (1969). He was also awarded two Orders of Lenin, the Order of the October Revolution, two Orders of the Red Banner of Labour and an Order of the Red Star.
