Abstract
The disclosure relates to a method for manufacturing a biocompatible wire, a biocompatible wire comprising a biocompatible metallic material and a medical device comprising such wire. The method for manufacturing a biocompatible wire comprises providing a workpiece of a biocompatible metallic material, cold working the workpiece into a wire, and annealing the wire, wherein a cold work percentage is 97 to 99%, wherein the cold working is a drawing with a die reduction per pass ratio in a range of 6 to 40%, and wherein the annealing is done in a range of 850 to 1100° C.
Claims6
A method for manufacturing a biocompatible wire, comprising:
- providing a workpiece of a biocompatible metallic material;
- cold working the workpiece into a wire;
- and
- annealing the wire;
- wherein a cold work percentage is 97 to 99%;
- wherein the cold working is a drawing with a die reduction per pass ratio in a range of 6 to 40%;
