Implant with increased carbon content at near-surface boundary layer |
摘要 |
Implant in the form of an intraluminal endoprosthesis, having a tubular body containing metallic material, optionally iron, whereby in at least a portion of the implant body the following are present in the structure of a near-surface boundary layer in comparison to the respective concentration in the remaining structure: an increased carbon content in a concentration of approximately 0.5% by weight to approximately 2% by weight; or an increased carbon and nitrogen content, wherein a concentration of carbon is approximately 0.5% by weight to approximately 7% by weight, and a concentration of nitrogen is approximately 0.5% by weight to approximately 17% by weight. |

1. An implant in the form of an intraluminal endoprosthesis, having a tubular body containing metallic material, optionally iron, wherein in at least a portion of the implant body the following are present in the structure of a near-surface boundary layer in comparison to the respective concentration in the remaining structure:
an increased carbon content, wherein a concentration of carbon is approximately 0.5% by weight to approximately 7% by weight, and an increased nitrogen content, wherein a concentration of nitrogen is approximately 5% by weight to approximately 12% by weight. |
