Abstract
The application discloses esters of hyaluronic acid, wherein a first part of the carboxylic functions is esterified with an araliphatic alcohol and a second part is esterified with at least one long-chain, straight aliphatic alcohol with between 10 and 22 carbon atoms. The possible remaining non-esterified carboxylic functions, if present, are salified. The application further discloses biocompatible threads having a multifilament conformation comprising filaments formed by the aforesaid esters, and their use in the fields of medicine and surgery.
