Abstract
Processes for treating polymeric surfaces to produce smooth, durable, slippery coatings which are able to withstand the rigors of sterilization and, long term exposure to human blood and other bodily fluids without substantial loss of their slipperiness.
Claims16
A process for treating a medical article or device having a polymeric surface to produce a smooth, durable, slippery coating comprising:
- applying to the polymeric surface of the said article or device a primer coat;
- applying to said surface a tie coat comprising a solution selected from aqueous solutions of polyacrylic acid, dimethyl formamide solutions of poly(methyl vinyl ether/maleic anhydride), 1:1 methanol/isopropanol solutions of poly(methyl vinyl ether/maleic anhydride) and solutions of poly(methyl vinyl ether/maleic anhydride) in one or more alcohols selected from the group comprising the lower alcohols of methanol through pentanol or mixtures thereof in water;
- and
- applying to said surface a slippery coating comprising a solution of polyvinylpyrrolidone.
A medical article or device having a polymeric surface which has been treated to produce a smooth, durable, slippery coating, said coating being formed by applying to the polymeric surface of the said article or device a primer coat comprising a solution selected from aqueous solutions of polyacrylic acid, dimethyl formamide solutions of poly(methyl vinyl ether/maleic anhydride) and 1:1 methanol/isopropanol solutions of poly(methyl vinyl ether/maleic anhydride);
- and applying to said surface a slippery coating comprising a solution of polyvinylpyrrolidone.
