FIELD: medicine.
SUBSTANCE: method involves sampling and washing native tissues and preserving them for 2-21 days in mixed ethylene glycol diglycyl ester and oligoepoxy compound with the branched structure of a hydrocarbon chain prepared in a 0.05-0.2 M phosphate buffer; that is followed by heparinisation of the biological tissue surface at 20-40°C for 2-14 hours.
EFFECT: method enables improving viscoelastic and thromboresistant characteristics of the biological prosthesis, increasing the sterilising effect and biomaterial resistance to calcification.
