| 主权项 | 1. A method for producing a biodegradable in vivo supporting device, comprising: (a) producing a biodegradable metal scaffold made from a magnesium alloy having a magnesium content of 97.45 wt. %, a manganese content of 1.8 wt. %, and a cerium content of 0.75 wt. %; (b) coating said biodegradable metal scaffold with a first biodegradable polymer coating having a first degradable rate; and (c) coating the biodegradable metal scaffold from step (b) with a second biodegradable polymer coating having a second degradable rate, wherein said second degradable rate is faster than said first degradable rate. | ||
