Abstract
A catheter assembly is disclosed, comprising a catheter, such as a urinary catheter, which at least a partly is provided with a hydrophilic coating. The catheter assembly further comprises a wetting fluid. The receptacle is in direct contact with the hydrophilic coating of the catheter over essentially the entire length of the part of the catheter being provided with the hydrophilic coating. This may e.g. be achieved by using a shrink wrap material. In order to accomplish adequate wetting, channels or the like may be provided on the inner surface of the receptacle or the outer surface of the catheter.

A urinary catheter assembly comprising:
- a urinary catheter, at least a part of which is provided with a hydrophilic coating;
- a wetting fluid;
- and
- a receptacle enclosing the wetting fluid and at least the part of the catheter being provided with the hydrophilic coating;
- wherein the receptacle is in direct contact with the hydrophilic coating of the catheter over essentially the entire length of said part of the catheter being provided with the hydrophilic coating, wherein the direct contact between the hydrophilic coating and the receptacle occurs in a number of contact points being distributed around a circumference of the catheter, said contact points being discrete contact points or contact points being continuously connected, and wherein at least one of an inner surface of the receptacle facing the hydrophilic coating and an outer surface of the hydrophilic coating facing the receptacle comprises a surface texture forming channels between the receptacle and the hydrophilic coating, wherein areas between the channels forms areas of direct contact between the receptacle and the hydrophilic coating.
