Design of alloys and microstructures - SIMAP

Finally, it was shown that the design of alloy compositions was essential for obtaining metallic glasses and controlling their properties, as it was for controlling the biodegradability of magnesium alloys for medical implants.

British Cardiovascular Society

Several animal studies have proven that our magnesium alloy has an effect on smooth muscle cell and endothelial cell proliferation whilst maintaining optimal vitality. The results achieved so far are quite favorable: the stent structures disappear gradually, and both the perfused and stent lumen area are consistently larger when compared to control vessels treated with conventional stents”.
