Biomaterial, injectable implant comprising it, its method of preparation and its uses

摘要

This invention relates to a biomaterial comprising an injectable bioresorbable polysaccharide composition wherein the polysaccharide may be succinochitosan glutamate. This invention also relates to a biomaterial comprising an injectable bioresorbable polysaccharide composition in which resorbable particles may be in suspension, the said particles comprising or consisting essentially of chitin and/or chitosan, which may be free of any additional formulation modifying agents, and a process for manufacturing the same. This invention also relates to a medical device including said biomaterial and to a method of repair or treatment including the filling of cavities in the human face or body.

主权项

1. An injectable gel comprising (a) a gel portion and (b) solid resorbable powder particles in suspension in the gel portion;
(i) wherein the solid resorbable powder particles consist essentially of chitin powder; (ii) wherein the injectable gel comprises from 0.1 wt. % to 10 wt. % of the solid resorbable powder particles by total weight of the injectable gel; (iii) wherein the gel portion comprises from 0.1 wt. % to 20 wt. % of a succinylated chitosan by total weight of the injectable gel; (iv) wherein the injectable gel has a viscosity that is suited for subcutaneous or intradermal injection into a human.
