Abstract

A method for manufacturing a bioresorbable implant, wherein a magnesium alloy is formed into an implant. A melt is pressed into a die and gases in the die induce turbulence in the inflowing melt, thereby enclosing gas, so that the porous implant is formed with a porosity, which increases from outside inwardly. The surface of the implant is substantially free from open pores.
