Claims
- 1. A medical device intended for introduction to the body comprising:a substrate suitable for introduction into the body, the surface of said substrate being coated with a cured polymeric composition, said composition comprising a first polymeric layer formed from at least a partial reaction of an aqueous dispersion or emulsion of a polymer having reactive organic acid functional groups present and two hydrophilic polymeric layers each having organic acid functional groups present, wherein said first polymer layer and at least one of the hydrophilic layers have a polyfunctional crosslinking agent capable of reacting with said organic acid functional groups; wherein said first hydrophilic polymeric layer coats said first polymeric layer and said second hydrophilic polymeric layer coats said first hydrophilic polymeric layer.
- 2. A medical device of claim 1, wherein said first polymeric layer, said first hydrophilic polymeric layer, and said second hydrophilic polymeric of the cured polymeric composition are an integral coating.
- 3. A medical device of claim 1, wherein said first hydrophilic polymeric layer further includes a polymer having reactive organic acid functional groups.
