<p>A stent system comprises a stent made of a conventional metal alloy, such as stainless steel, treated with chains of peptides ("anchors") which comprise functionality to bind to the metal surface and to bind to other peptides (which other peptides are termed "recognition" peptides) and recognition peptides, which comprise one end which binds to ("recognizes") the anchor peptide and one end which is bound to a radiodense dye, which system enhances radiopacity relative to the stent alone.</p> |
