Abstract

"COMPOSIçãO, MéTODO PARA A PREPARAçãO DA MESMA, BIOMATERIAL, E, USO DE UMA COMPOSIçãO OU DE UM BIOMATERIAL". São proporcionadas composições novas consistindo de rede semi-interpenetrante de derivados reticulados solúveis em água de polissacarídeos básicos e um componente não reticulado, que é um polissacarídeo aniónico. Também são descritos métodos para a produção de tais composições. Preferivelmente o polissacarídeo básico é quitosana ou um seu derivado e o polissacarídeo aniónico é ácido hialurónico. As composições podem ser transformadas em géis ou filmes, por exemplo, e assim encontram uso em uma ampla variedade de aplicações médicas nos campos de dermatologia, cirurgia plástica, urologia e ortopedia.
