METHOD FOR OBTAINING THROMBORESISTANT POLYMER MATERIALS Russian patent published in 2010 - IPC A61L27/50 A61L27/14 A61L29/14 A61L33/06 

FIELD: medicine.

SUBSTANCE: invention refers to the field of polymer chemistry and medicine, namely to method for obtaining thromboresistant polymer materials which have widespread application in medical industry for manufacturing workpieces on blood contact, for example blood-vessels prostheses, parts of bioartificial organs implanted into living body, bloodlines for artificial blood-circulation apparatus, storages for storage and blood transfusion etc. Method for obtaining thromboresistant polymer materials implies mixture polymer with extender, and is inert to blood coagulation water-soluble compounds in amounts of 0.3-3.5 wt % used as extender.

EFFECT: invention enables to produce thromboresistant polymer materials with lowered tendency to adhesion of platelets and lowered ability to formation of fibrinous thrombs on the surface of material in the absence of influence of whole blood coagulation system, as evidenced by increase of buildup time of fibrinous clod from 60-80 seconds to 110-240 seconds.
