Abstract
The invention is directed to the use of a wetting agent having a boiling point higher than 100° C. and a viscosity lower than 500 mPa.s, wherein the wetting agent comprises water in an amount between 0 and 4.9 wt % based on the total weight of the wetting agent, for the lubrication of a hydrophilic polymer coating. The invention further relates to a medical device comprising a hydrophilic polymer coating that is wetted by a wetting agent, a method for the preparation of a medical device and a package comprising a medical device.

A package comprising a medical device, the medical device comprising:
- a hydrophilic polymer coating that is wetted by a wetting agent having a boiling point higher than 100° C. and a viscosity lower than 500 mPa.s, wherein
- the wetting agent comprises water in an amount between 0 and 4.9 wt % based on the total weight of the wetting agent, wherein
- the package is impermeable to vapor, and wherein
- the medical device is sterilized.
A method for the preparation of a medical device comprising the steps of:
- (a) providing a medical device that is at least partially coated with a hydrophilic polymer coating,
- (b) providing a wetting agent with a boiling point higher than 100° C. and a viscosity lower than 500 mPa.s, wherein the wetting agent comprises water in an amount between 0 and 4.9 wt % based on the total weight of the wetting agent,
- (c) contacting the part of the medical device that is coated with the hydrophilic polymer coating with the wetting agent in such a way that the hydrophilic coating is lubricated by the wetting agent, and
- (d) sterilizing the medical device.
