US Patent 12070533 Metal alloy and medical device containing same

There is described a bioresorbable metal alloy which is particularly suitable for the formation of bioresorbable medical devices, for example stents. The metal alloy essentially comprises 3.2 to 4.8% by weight lithium, 0.5 to 2.0% by weight yttrium; and the balance being magnesium, in addition to any trace elements. The metal alloy can be drawn into a wire which can be shaped into a stent scaffold. The stent can be produced using one or more stent scaffolds together with one or more bioresorbable polymer connectors, for example formed from PLGA.
