Abstract

Naturlig avledede bioprotetiske materialer behandles med epoksid-tverrbindingsmidler. I noen utførelser tverrbindes vevet med epoksider av lav molekylvekt i vandige oppløsninger ved høye pH-nivåer. I andre utførelser tverrbindes vevet ved fysiologiske pH-nivåer med epoksid-tverrbindingsmidler katalysert med tertiære eller kvatemære aminer, slik som Tris eller imidazol. I en fordelaktig utførelse blir bioprotetisk vev tverrbundet og derivatisert med et antiforkalkningsmiddel slik som et polyfosfonat- antiforkalkningsmiddel, ved anvendelse av et polyfosfonat:polyepoksid-monoaddukt.
