Implant, preferably intraluminal endoprosthesis comprises a body portion containing at least predominantly a material with iron as main constituent. The material contains sulfur (0.2-1 wt.% or more, preferably 0.5 wt.%), and at least one element chosen from calcium, manganese and magnesium as second minor constituent. An independent claim is included for method for producing an implant, which involves (a) producing a melt with a material composition, (b) producing a slab by cooling the melt in an adequate mold in a certain predetermined cooling rate, and optionally carrying out at least one hot forming step for producing a semifinished portion, and (c) post-processing the semifinished portion or slab, preferably by laser cutting until the desired shape of the implant body is produced. ACTIVITY : Vasotropic. No biological data given. MECHANISM OF ACTION : None given. |
