An intravascular stent has a coat comprising a crosslinked amphiphilic polymer and a sparingly water soluble matrix metalloproteinase inhibitor (MMPI). Preferably the polymer is formed from 2-methacryloyloxy-2′-ethyltrimethylammonium phosphate inner salt, C4-18 alkyl methacrylate and reactive and/or crosslinking monomer and the MMPI is a hydroxamic acid, more preferably batimastat. Preclinical and clinical results are reported, showing good luminal areas and reduced intimal thickening.
