A catheter assembly includes a hydrophilic catheter; a wetting fluid for wetting of the catheter; and a receptacle enclosing at least the insertable part of the catheter and the wetting fluid. The wetting fluid is a solution incorporating at least one osmolality-increasing compound, and the total concentration of the osmolality-increasing compound(s) preferably exceeds 600 mOsm/dm3. The wetting fluid could either be arranged in contact with the hydrophilic surface layer of the catheter in the receptacle, for preservation of the hydrophilic surface layer in a wetted state during accommodation in said receptacle and provision of a ready-to-use catheter assembly, or be arranged to keep the wetting fluid separated from the hydrophilic surface layer of the catheter during storage, but to be brought into contact with said hydrophilic surface layer upon activation before an intended use of the catheter.
A urinary catheter assembly for human use, comprising:
A wetting fluid for activation of a hydrophilic surface layer in order to produce a low-friction surface character of said hydrophilic surface layer by treatment by said the wetting fluid, wherein the wetting fluid comprises at least one dissolved osmolality-increasing compound, wherein the total concentration of the osmolality-increasing compound(s) exceeds 600 mOsm/dm3.
A method for producing a urinary catheter assembly for human use, comprising:
Method of using a wetting fluid solution for activation of a urinary catheter for human use having on its surface, on at least an insertable part thereof, a hydrophilic surface layer providing low-friction surface character of the urinary catheter by treatment with said wetting fluid, comprising the steps:
A urinary catheter assembly for human use, comprising:
