Beschreibung
Zusammenfassung:	FIELD: medicine.SUBSTANCE: invention refers to medicine and discloses a biomaterial for the manufacture of heart valve prostheses and a method for preparing it. Biomaterial includes bovine pericardium coated with nanodiamonds of detonation synthesis, having positive electrokinetic potential in water, with content of nanodiamonds of 1.5 to 4 mg per gram of biological tissue, with average size of aggregates from 17 to 28 nm on surface of biomaterial.EFFECT: biomaterial is characterized by high strength and wear resistance and is intended for improving mechanical properties of materials for making artificial heart valves.7 cl, 4 dwg, 2 ex Изобретение относится к медицине и раскрывает биоматериал для изготовления протезов клапанов сердца и способ его получения. Биоматериал включает бычий перикард, покрытый наноалмазами детонационного синтеза, обладающими положительным электрокинетическим потенциалом в воде, с содержанием наноалмаза от 1.5 до 4 мг на грамм биологической ткани, со средним размером агрегатов от 17 до 28 нм на поверхности биоматериала. Биоматериал характеризуется высокой прочностью и износостойкостью и предназначен для улучшения механических свойств материалов для изготовления искусственных клапанов сердца. 2 н. и 5 з.п. ф-лы, 4 ил., 2 пр.
