Abstract
A urinary catheter assembly is provided. The catheter assembly has a first outer package (), which contains a second inner package (). The second inner package includes a hydrophilic coated, intermittent catheter) and liquid swelling medium. The first outer package is made of a first material with a WVTR value between 1 and 6 g/(m·24 h) and the second inner package is made of a second material with a second WVTR value below 3 g/(m·24 h). An intermediate cavity () is defined inside the first outer package, but outside the second inner package. The first and second WVTR-values are balanced in such a way that the relative humidity (RH) is below 90% in the intermediate cavity. This prevents condensation on the inner surface of the first outer package and on the outer surface of the second inner package.
