| 发明名称 | Medical implant comprising a biodegradable magnesium-based alloy and method for its manufacture | ||
| 摘要 | A medical implant comprises a biodegradable magnesium-based alloy of which at least a part of its surface layer comprises a magnesium carbonate. A method for the manufacture of a biocompatible, corrosion-inhibiting protective surface layer on a medical implant comprising a magnesium-based alloy, comprises: providing an implant comprising a magnesium-based alloy to be coated; placing the implant into a reactor chamber; exposing at least part of the surface of said implant to an atmosphere comprising humid carbon dioxide to produce a coating on the surface of the implant comprising a magnesium carbonate of the formula x MgCO3.y Mg(OH)2, whereby x+y=1; removing the implant from the reactor chamber; and drying the surface of the implant. | ||

| 主权项 | 1. A medical implant comprising: a biodegradable magnesium-based alloy of which at least a part of its surface layer comprises a magnesium carbonate, wherein the magnesium carbonate has the formula: Mg2[(OH)2(CO3)].3 H2O; orMg[(OH)x(CO3)y].(H2O)z whereby x+y=2 and z=0.25 to 2 wherein the magnesium carbonate is formed by exposing at least a part of the surface of the medical implant to an atmosphere comprising humid carbon dioxide. | ||
