Abstract:
The present disclosure relates to a coating for medical devices. The lubricious coating includes a primer layer and a top coating layer as well as methods of making and using the same. The primer layer includes a reaction cured product of a multifunctional acrylate and an acid functionalized monoacrylate. The top coating layer includes a reaction cured product of a mixture that includes a hydrophilic polymer comprising polyvinylpyrrolidone, an acid functionalized monoacrylate, and a hydrophilic monomer. The lubricious coating may be coated onto medical devices to form a sensing guide wire, an ultrasound imaging device, and an intravascular imaging device. Associated devices and methods are also provided.
