METHOD OF INCREASING REGENERATIVE POTENTIAL OF IMPLANTED MATERIAL FOR RESTORATIVE SURGERY (EMBODIMENTS) Russian patent published in 2020 - IPC A61F2/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to embodiments of methods of increasing regenerative potential of implanted material for restorative surgery. In the first embodiment, it is made of non-conductive polymer by application of coating from bioresorbable biopolymer onto implanted material. First, on the surface of the implanted material made from a non-electroconductive polymer, 100–200 nm thick conductive layer is formed, which is then coated with a bioresorbable biopolymer by electrostatic moulding from a polymer solution in an organic solvent, having electrical conductivity of 9–10 mcS/cm, in the form of a layer of microfibres with a diameter of up to 5000 nm and thickness of 15–50 mcm from a bioresorbable biopolymer: polyhydroxybutyrate, polylactide or mixtures thereof. In the second embodiment, when making the implanted material from metal, the bioresorbable biopolymer coating on the implanted material is applied by electrostatic moulding from a solution of a polymer in an organic solvent having specific conductivity of 9–10 mc/cm, in the form of a layer of microfibres with a diameter of not more than 1400 nm and a thickness of not less than 50 mcm from a bioresorbable biopolymer: polyhydroxybutyrate, polylactide or mixtures thereof.

EFFECT: technical result is higher efficiency and multiple increase in specific surface of biopolymer layer made of fibres of submicron size, having conductive and adhesive properties.
