Abstract

A medical device substrate with a coating including a functional layer located on the substrate, with the functional layer including at least one sugar alcohol and being bonded to the substrate directly or indirectly via a functionalization of the sugar alcohol. Alternatively, the functional layer may also include other saccharides, in which case it is essential that polymerization of the saccharides takes place only upon bonding to the substrate. The inventive medical device exhibits reduced platelet adhesion and aggregation.
