Abstract

UN METODO PARA TRATAR UN MATERIAL COLAGENOSO, TALES COMO TEJIDOS DE VALVULA AORTICA PORCINA O EL PERICARDIO BOVINO, EXPONIENDO EL BIOMATERIAL A UN ALCOHOL PARA INHIBIR LA CALCIFICACION IN VIVO. EL BIOMATERIAL, PREFERIBLEMENTE GLITARALDEIDO-PRETRATADO, ES SOMETIDO A UNA SOLUCION ACUOSA DEL 60 AL 80% DE ALCOHOL ALIFATICO BAJO, TAL COMO ETANOL DURANTE UN PERIODO DE AL MENOS 20 MINUTOS, Y PREFERIBLEMENTE 24 A 72 HORAS. EL BIOMATERIAL ES ACLARADO, Y ALMACENADO BIEN EN UN AMBIENTE SIN GLUTARALDEIDO O EN UNA SOLUCION ETANOLICA DE GLUTARALDEHIDO.
