hallo,

in de zin dat de katheder met water in contact mag en kan komen zoder dat het materiaal aangetast wordt.

misschien helpt dit je wel

groetjes

There´s a typo in your term. Should be hydrophilically.

As I understand the coating is used to facilitate movements of the catheter inside the body not to protect the catheter. Hydrophilic coatings are used for better lubrication; they should be better than non-hydrophilic ones. So, I am affraid, the term "bescherming" doesn´t apply here.

Sites in English:

Hydrophilic Coating: Lubricious coating facilitates device placement in vasculature. The only hydrophilically coated EP catheter to date.

Consistent Coating Performance
The Mirage is hydrophilically coated with the most advanced coating technology that allows for excellent lubricity during catheter navigation. The coating is adhered to the guidewire shaft and distal tip by a method that provides enhanced durability and tenacity throughout a procedure.

My suggestion is:

katheter met niet-hidrofiele deklaag

I think you´re on the safe side with this translation. I found the term in French in a pdf document:


hydrophilically coated = couverte d´un revetenment hydrophile

http://pctgazette.wipo.int/pdf/361998-1.pdf.

Couverte / revetiment is definitelly (dek)laag

hydrophile (French) = hidrophiel

(try, for example, Eurodicautom)

I hope this helps.

The best of luck.
