HYALURONIC ACID ESTERS, THREADS AND BIOMATERIALS CONTAINING THEM, AND THEIR USE IN SURGERY

摘要

The application discloses esters of hyaluronic acid, wherein a first part of the carboxy functions is esterified with an araliphatic alcohol and a second part is esterified with long-chain, straight aliphatic alcohols with between 10 and 22 carbons atoms. The possible remaining non-esterified carboxy functions, if present, are salified. The application further discloses biodegradable threads constituted by the aforesaid esters, and their use in the fields of medicine and surgery.
