| abstract |
An article of metal, glass, ceramics or plastics having a surface for contact with tissue or with circulating blood, has a surface coating of an organopolysiloxane and heparin, in which coating the organopolysiloxane is adherent to the surface of the article and has cationic groups that form ionic bonds with anionic groups of the heparin. The surface for contact with circulating blood may be an interior surface of a cannula or tubing or of a blood oxygenator or it may be a working surface of a blood filter. The polymer may be poly-[dimethylsiloxane-co-methyl-(3-hydroxypropyl)siloxane]-graft-poly(ethylene glycol) [3-(trimethylammonio) propyl chloride] ether. A method is also provided for forming a coated article as aforesaid, said method comprising contacting said surface with a solution in a volatile organic solvent of an organopolysiloxane and with heparin, the organopolysiloxane being adherent to the surface of the article and having cationic groups that form ionic bonds with the anionic groups of the heparin, and removing said volatile solvent. |
