A method for producing an implant, such as an intraluminal endoprosthesis, the method including producing a melt with a material composition of iron, sulfur at a concentration of more than 0.2% by weight and not more than 1% by weight, and at least one element selected from the group consisting of calcium, manganese and magnesium; producing a slab by cooling the melt in a mold at a predetermined cooling rate to produce a semi-finished part; and post-processing the semi-finished part to form the desired shape of the implant body. |

1. A method for producing an implant, optionally an intraluminal endoprosthesis, the body of which comprises at least predominantly a material with iron as the main constituent, comprising the following steps:
a) producing a melt with a material composition comprising iron as a main constituent, sulfur as first minor constituent with a concentration of more than 0.2% by weight and not more than 1% by weight, optionally not more than 0.5% by weight, and a second minor constituent of at least one element selected from the group consisting of calcium, manganese and magnesium; b) producing a slab by cooling the melt in an adequate mold at a predetermined cooling rate and, optionally, carrying out at least one hot forming step for producing a semi-finished part; and c) post-processing the semi-finished part or slab, optionally by laser cutting, until the desired shape of the implant body is produced. |
