Biodegradable implant and method for manufacturing same

Abstract

This invention relates to a biodegradable implant including magnesium, wherein the magnesium contains, as impurities, (i) manganese (Mn); and (ii) one selected from the group consisting of iron (Fe), nickel (Ni) and mixtures of iron (Fe) and nickel (Ni), wherein the impurities satisfy the following condition: 0<(ii)/(i)≦5, and an amount of the impurities is 1 part by weight or less but exceeding 0 parts by weight based on 100 parts by weight of the magnesium, and to a method of manufacturing the same.

         26 . A method of manufacturing a biodegradable implant, comprising:
 i) providing a magnesium alloy represented by Chemical Formula 1 below comprising based on total weight thereof,   
       from 4.51 wt % to 10.8 wt % of Ca; 
       from 0.1 to 5 wt % of X, 
       and a remainder of Mg; and
 ii) forming the magnesium alloy:
   Mg—Ca—X   <Chemical Formula 1>
 
 wherein X is Mn or Zn. 
 
 
     
     
         27 . The method of  claim 26 , wherein i) comprises:
 i-1) preparing a porous structure; and   i-2) filling pores of the porous structure with the magnesium alloy.   
     
     
         28 . The method of  claim 26 , wherein ii) is performed using one or more selected from the group consisting of cooling, extrusion, and metal processing.
