Abstract
A storage package (1) contains a medical device (7) having a coated surface (8 ) which exhibits a reduced friction when wetted with a wetting liquid and a supply of the wetting liquid (9). The package is adapted such that the coated surface of the medical device is maintained contact with the supply of wetting liquid during storage. A good shelf-life for the medical device is achieved an where the medical device is a urethral catheter the catheter is immediately “ready-for-use” after the package has been opened.
Claims48
A storage package comprising a supply of a wetting liquid, a urinary catheter having a coated surface which exhibits reduced friction when wetted with the wetting liquid, and a container within which the catheter and the wetting liquid are contained, wherein the coated surface comprises a coating on a substrate comprising a polyether block amide, and wherein during storage, the coated surface of the urinary catheter is constantly maintained in direct contact with said wetting liquid.
A storage package, comprising a container which defines a closed cavity, a urinary catheter positioned in the closed cavity and having a coated polyether block amide substrate surface supporting a surface coating which exhibits a reduced friction when wetted with a wetting liquid, and a volume of the wetting liquid in the closed cavity sufficient for the surface coating to be maintained constantly wetted thereby during storage.
A ready-to-use urinary catheter assembly comprising a container, said container containing a urinary catheter having a hydrophilic layered surface which exhibits a reduced friction when wetted with a wetting liquid, wherein the container is pre-filled with an unenclosed supply of the wetting liquid, whereby during storage, the whole of the hydrophilic layered surface is constantly maintained in direct contact with said wetting liquid.
A method for sterile packaging of a urinary catheter having a surface which exhibits a reduced friction when wetted with a wetting liquid, comprising the following steps:
- providing a container;
- placing the urinary catheter in the container together with the wetting liquid in such a way that the surface of the urinary catheter is maintained in contact with the wetting liquid during storage;
- sterilizing the urinary catheter and the wetting liquid;
- and
- scaling the container.
A storage package comprising a unrinary catheter having a coated surface which exhibits a reduced friction when wetted with a wetting liquid and a supply of the wetting liquid, wherein the storage package is pre-filled with an unenclosed supply of the wetting liquid, whereby the coated surface of the a urinary catheter is constantly maintained in direct contact with the wetting liquid during storage.
