Abstract

"PROCESSO DE OBTENçãO DE ENDOPRóTESE REVESTIDA COM CELULOSE BIOSSINTéTICA E ENDOPRóTESE RESULTANTE". Compreendendo uma armação de malha de arame revestida por um material biocompatível e, mais particularmente, a uma endoprótese substancialmente cilíndrica expansível para o tratamento da estenose arterial, revestida por uma membrana celulose biossintética. O referido processo compreende a colocação da armação num molde de material impermeável a líquidos e permeável a gases, juntamente com um meio de cultura inoculado com um microorganismo produtor de celulose tal como o Acetobacter xylinum, resultando na formação de uma membrana de celulose justaposta à parede interna do dito molde. A membrana pode ser impregnada com agentes terapêuticos para liberação local durante um período de tempo de dias ou semanas.
