Abstract (en)

[origin: WO9603164A1] A flexible hydrophilic coating on a device which is to contact body fluid and particularly for flexible substrates on intracorporeal devices such as balloons on dilatation catheters. The coating includes at least 30 % of a copolymer of a hydrophilic monomer and a plasticizer monomer. A presently preferred hydrophilic monomer is acrylamide and the presently preferred plasticizer monomer is methoxy (polyethylene glycol) mono methacrylate where the polyethylene glycol moiety has a molecular weight of about 1000. Other hydrophilic polymers, such as n-vinyl pyrrolidone, may also be incorporated into the coating. Both polymers are treated to attach latent photoactive groups to facilitate the bonding thereof to a substrate.
