Abstract:
The invention provides a durable, lubricious coating for a medical article that can be prepared from a first polymer that is synthetic, soluble in a polar liquid, and having first reactive groups, and a second polymer that is synthetic, hydrophilic, and that includes second reactive groups. The first reactive groups and a portion of the second reactive groups react to bond the first polymer to the second polymer. A portion of the second reactive groups remains unbonded which, upon neutralization, provide lubricious properties to the coating. In some aspects the coating is formed using a crosslinking agent having latent reactive groups. The coatings provide particularly long dry out times and are very useful for catheterization processes. In addition, the coatings can be subject to sterilization with ethylene oxide and retain very good durable and lubricious properties.
