Abstract

A stent comprising a basic stent body, at least one anchor group on the surface of the basic stent body, and at least one biomolecule which is bound to the at least one anchor group, the anchor group being the same or different and selected from the group of compounds with the general formula (I) (R.sup.2O).sub.2(O)P-L-(CH.sub.2).sub.x-M-R.sup.1 (I) in which R.sup.1 represents --COOH, --OH, --SH, --NH.sub.2, benzophenone or benzophenone derivatives, R.sup.2 represents hydrogen, --CH.sub.2CH.sub.3 or --CH.sub.3, L represents a single bond or --O--, M represents a single bond or --(CH.sub.2--CH.sub.2--O).sub.y, x represents an integer from 1 to 25, y represents an integer from 1 to 25and the biomolecule or biomolecules are selected as the same or different from the group consisting of compounds which promote the attachment of the endothelial progenitor cells to the stent surface.
