Abstract
The invention concerns methods of coating stents and stents produced in accordance therewith. The object of the invention is to provide methods of coating stents with a polysaccharide layer which has improved adhesion capacity on the substrate surface of the implant, and to afford correspondingly functionalized stents. That is achieved inter alia by covalent bonding of a non-crosslinked hyaluronic acid to a substrate surface of the stent with the formation of hyaluronic acid layer and crosslinking of the hyaluronic acid layer.
