| 发明名称 | Biodegradable implant and fabrication method thereof | ||
| 摘要 | The present invention can suitably be used even in a site where hydrogen gas is metabolized slowly, such as the osseous tissue. Provided is a biodegradable implant including a biodegradable magnesium member formed of a magnesium alloy and coating layers that coat the biodegradable magnesium member, thereby reducing the degradation rate thereof in a living organism, wherein a depression to be infiltrated by an osteoblast is formed in a surface of the biodegradable magnesium member. | ||

| 主权项 | 1. A biodegradable implant comprising: a biodegradable magnesium member formed of a magnesium alloy; and a coating layer that coats the biodegradable magnesium member, thereby reducing a degradation rate thereof in a living organism, wherein a depression to be infiltrated by an osteoblast is formed in a surface of the biodegradable magnesium member, wherein the coating layer includes: a high-purity magnesium layer that is formed of magnesium and a metal other than magnesium, a content rate of the metal other than magnesium is lower than a content rate of the metal in the biodegradable magnesium member, andan oxide layer provided at an outermost side and formed of an oxide, wherein the content rate of the metal other than magnesium in the coating layer is equal to or less than 1/10 of the content rate of the metal other than magnesium in the biodegradable magnesium member. | ||
