FILLER EXHIBITING EXCELLENT FILLER PROPERTIES, CONTAINING A HYALURONIC ACID HYDROGEL Russian patent published in 2022 - IPC A61L27/20 A61L27/52 A61M5/28 

FIELD: medicine.

SUBSTANCE: group of inventions relates to a filler containing a hyaluronic acid hydrogel. Filler for soft tissues contains a hyaluronic acid hydrogel including hyaluronic acid, a salt of hyaluronic acid, or crosslinked hyaluronic acid, wherein the ratio of lifting capacity per unit content (wt./wt.%) of hyaluronic acid contained in the filler to the degree of modification (mol.%) is from 60 to 180 ((Pa*N/ (wt./wt.)%/ mol.%); wherein the filler has all properties of high cohesive capacity of a one-phase filler with hyaluronic acid and high elasticity of a two-phase filler with hyaluronic acid. Also disclosed are a method for producing a filler, a filled syringe, a biological material for regenerating soft tissues, a method for regenerating soft tissues, and a method for reducing wrinkles.

EFFECT: group of inventions provides enhanced properties of high viscoelasticity, has the advantages of both one and two-phase fillers with a hydrogel of hyaluronic acid.
