Hydrophilic lubricant coatings for medical devices

摘要

A medical device comprising at least one tubular member having an inner surface and an outer surface, said inner surface of said tubular member is at least occasionally subjected to contact with at least one second surface, said tubular member is coated on said inner surface by the process of:
a) pre-treating said inner surface of said tubular member with a crosslinkable primer composition wherein said crosslinkable component is a crosslinkable silicone; and
b) coating said inner surface of said pre-treated tubular member with a hydrophilic lubricious coating,
wherein said hydrophilic coating is present to reduce the friction between the inner surface of said tubular member and said second surface caused by movement.
