Abstract
A process for producing implants made of a bioresorbable metal, particularly magnesium alloys or zinc alloys, in which the material properties of the magnesium or the zinc are changed and the processing and utilization properties are improved by combining process steps for adjusting the properties of the material and subsequent machining. In this way it is possible to produce thin-walled tubular implants, particularly blood vessel support stents, from bioresorbable magnesium or zinc alloys, which are readily deformable without the risk of fracture during implantation.
