Abstract | A bioerodible endoprosthesis includes a bioerodible body including an alloy comprising at least 85 weight percent magnesium and at least one high-melting- temperature element having a melting temperature of greater than 700 °C. The alloy has a microstructure including equiaxed magnesium-rich phase grains and optionally high-melting-temperature intermetallic phases. The equiaxed magnesium-rich phase grains have an average grain diameter of less than or equal to 10 microns. High- melting-temperature intermetallic phases, if present, can have an average longest dimension of 3 microns or less.
Une endoprothèse bioérodable comprend un corps bioérodable comprenant un alliage comportant au moins 85 % en poids de magnésium et au moins un élément à température de fusion élevée présentant une température de fusion supérieure à 700 °C. L'alliage présente une microstructure comprenant des grains équiaxiaux d'une phase riche en magnésium et, éventuellement, des phases intermétalliques à température de fusion élevée. Les grains équiaxiaux de la phase riche en magnésium présentent un diamètre de grain moyen inférieur ou égal à 10 microns. La dimension la plus longue moyenne des phases intermétalliques à température de fusion élevée, le cas échéant, peut être inférieure ou égale à 3 microns. |
