Abstract
Hydrophilic coatings including a polymer matrix having voids wherein microparticles having a lubricious liquid are located within the voids.
Claims21
A lubricious hydrophilic coating, comprising:
- a hydrophilic polymer matrix having voids;
- and
- microparticles comprising a lubricating liquid located in the voids of the hydrophilic polymer matrix.
A method of making a medical device having a hydrophilic coating:
- applying a hydrophilic coating formulation to a surface of the medical device, the hydrophilic coating formulation comprising a hydrophilic polymer and microparticles comprising a lubricating liquid or microparticle precursors;
- and
- forming a hydrophilic coating on the surface of the medical device from the hydrophilic coating formulation, wherein the hydrophilic coating includes a matrix having voids and microparticles comprising a lubricating liquid or microparticle precursors are located in the voids.
