摘要：
interaliaThere is described a device having a surface comprising a layered coating wherein the outer coating layer comprises a plurality of cationic hyperbranched polymer molecules characterized by having (i) a core moiety of molecular weight 14 1 000 Da (ii) a total molecular weight of 1 500 to 1 000 000 Da (iii) a ratio of total molecular weight to core moiety molecular weight of at least 80:1and (iv) functional end groups whereby one or more of said functional end groups have an anti coagulant entity covalently attached thereto.
