1. A method of processing a medical device formed from a bioabsorbable metallic material, comprising:

  • generating a beam of radiation onto the bioabsorbable metallic material, the radiation beam creating a heat affected zone (HAZ);

    providing a liquid;

    reducing an oxygen concentration in the liquid to below about 0.5 mg/L; and

    transmitting a fluid column of the liquid around the radiation beam onto the HAZ to thereby cool the HAZ and reduce a concentration of oxygen surrounding the HAZ, wherein the fluid column is parallel to the radiation beam.
