  • Urinary catheter assembly with a ready-to-use catheter
    Patent number: 6059107

The package (7) is made with walls of a gas impermeable material to accommodate a catheter pretreated with said liquid swelling medium for long time preservation of said low-friction surface character and provision of a ready-to-use catheter assembly.
