Abstract

liga para uso em um dispositivo de uso médico absorvível, fio, e dispositivo de uso médico. uma liga de magnésio contém uma pequena quantidade de lítio, zinco, cálcio e manganês. por exemplo, a liga de magnésio pode incluir entre 1-5% em peso de lítio, entre 0,2-2,0% em peso de zinco, entre 0,1-0,5% em peso de cálcio e entre 0,1-0,8% em peso de manganês. estes elementos de liga são todos elementos nutrientes, de modo que a presente liga pode ser rompida com segurança in vivo e, em seguida, absorvida e/ou expelida do corpo. li, zn, ca e mn contribuem cada um para o fortalecimento da liga em solução sólida. o ca também atua como um refinador de grãos, enquanto o zn e o ca formam compostos intermetálicos de fortalecimento e controle de corrosão. opcionalmente, a liga também pode incluir uma pequena quantidade de ítrio para aumentar a força e resistência à corrosão.
