Abstract

A catheter assembly includes a catheter, a coating, a fluid containing sleeve, and a container. The catheter may include one or more distal drainage openings. The coating may be disposed on an outer surface of the catheter. The fluid containing sleeve may have an outer foil layer and be configured for positioning over the outer surface of the catheter to maintain the coating in a hydrated state. The container may enclose the catheter and the fluid containing sleeve. Substantially all fluid in the container may be disposed in the fluid containing sleeve.

First claim

What is claimed is:

1. A catheter assembly, comprising:
a catheter including one or more distal drainage openings;
a coating disposed on an outer surface of the catheter;
a fluid containing sleeve having a foil outer layer, the fluid containing sleeve configured for positioning over the outer surface of the catheter to maintain the coating in a hydrated state; and
a container enclosing the catheter and the fluid containing sleeve, wherein substantially all fluid in the container is in the fluid containing sleeve.

2. The catheter assembly according to claim 1 , wherein the container includes a foil layer.

3. The catheter assembly according to claim 2 , wherein the foil layer is a sole layer of the container.

4. The catheter assembly according to claim 2 , wherein the container includes a plurality of layers, the foil layer of the container being an inner layer in contact with the foil outer layer of the fluid containing sleeve.

5. The catheter assembly according to claim 4 , wherein the foil layer of the container is secured to the foil outer layer of the fluid containing sleeve.

6. The catheter assembly according to claim 2 , wherein the foil layer of the container is generally cylindrical.

7. The catheter assembly according to claim 1 , wherein the fluid containing sleeve is structured and arranged to swell when exposed to a fluid.

8. The catheter assembly according to claim 1 , wherein the fluid containing sleeve is structured and arranged to absorb about 90% of its weight in fluid.

9. The catheter assembly according to claim 1 , wherein the container comprises a sealed package.

10. The catheter assembly according to claim 9 , wherein the sealed package is a fluid impermeable package.

11. The catheter assembly according to claim 1 , wherein the fluid containing sleeve has a wall thickness that is ⅛ inch or greater.

12. The catheter assembly according to claim 1 , wherein the fluid containing sleeve comprises a material selected from the group consisting of a hydrogel, a hydrophilic polymer, an extruded polyurethane, and a polyether polyurethane-urea.

13. The catheter assembly according to claim 1 , wherein the fluid containing sleeve comprises a hydrophilic polymer selected from the group consisting of polyethylene oxide, poly vinyl alcohol, carboxy methyl cellulose, hydroxyl ethyl cellulose, hydroxyl ethyl methacrylate, acrylic polymers, and collagen.

14. The catheter assembly according to claim 1 , wherein the coating is selected from the group consisting of a hydrateable coating, a lubricious coating, a hydrophilic biocompatible coating, and combinations thereof.

15. The catheter assembly according to claim 1 , wherein the fluid containing sleeve is disposed over the catheter in the container, and wherein the catheter is removable from the container without fluid leaking out of the container.

16. The catheter assembly according to claim 15 , wherein the fluid containing sleeve is non-removably coupled to the container.

17. The catheter assembly according to claim 15 , wherein the catheter is removable from the container along with the fluid containing sleeve.

18. The catheter assembly according to claim 1 , wherein the catheter includes a funnel at a proximal end therof.

19. The catheter assembly according to claim 1 , wherein the fluid containing sleeve comprises a gripping end which does not contain fluid and allows a user to grip the fluid containing sleeve without fingers of the user becoming exposed to fluid.

20. The catheter assembly according to claim 1 , wherein the container comprises a first compartment containing the catheter and a second compartment containing the fluid containing sleeve.

21. The catheter assembly according to claim 20 , wherein the catheter is removable from the first compartment and insertable into the fluid containing sleeve in the second compartment.

22. The catheter assembly according to claim 21 , further comprising a first removable cover or openable section allowing a user to access and remove the catheter from the first compartment, and a second removable cover or openable section allowing the user to insert the catheter into the second compartment.

23. The catheter assembly according to claim 1 , wherein the container comprises a single flexible compartment which encloses the catheter and the fluid containing sleeve while axially separated from each other and is configured to allow a user to position the catheter into the fluid containing sleeve while the catheter and the fluid containing sleeve remain enclosed within the single flexible compartment.
