Abstract

A catheter assembly includes a catheter, a fluid containing sleeve, and a container. The catheter may include a tubular portion between a proximal end and a distal end, a coating on a length of the tubular portion, and at least one drainage opening on the distal end. The fluid containing sleeve is designed for arrangement on the tubular portion to maintain the coating in a hydrated state. The container may have at least one foil inner layer containing therein the catheter and the fluid containing sleeve. Substantially or nearly all fluid contained 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:
a tubular portion between a proximal end and a distal end;
a coating on a length of the tubular portion; and
at least one drainage opening on the distal end;

a fluid containing sleeve designed for arrangement on the tubular portion and for maintaining the coating in a hydrated state, the fluid containing sleeve having a foil outer layer; and
a container having at least one foil layer containing therein the catheter and the fluid containing sleeve, wherein substantially or nearly all fluid contained in the container is disposed in the fluid containing sleeve.

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

3. 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.

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

5. The catheter assembly according to claim 4 , wherein the sealed package is a fluid impermeable package.

6. The catheter assembly according to claim 1 , wherein the at least one foil layer of the container surrounds substantially all of the fluid containing sleeve.

7. The catheter assembly according to claim 6 , wherein the at least one foil layer of the container is secured to an outer surface of the fluid containing sleeve.

8. The catheter assembly according to claim 6 , wherein the at least one foil layer of the container is generally cylindrical.

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

10. 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.

11. 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.

12. The catheter assembly according to claim 1 , wherein the catheter comprises a coating arranged at least on an outer surface of the distal end, the coating selected from the group consisting of a hydrateable coating, a lubricious coating, and a hydrophilic biocompatible coating.

13. The catheter assembly according to claim 1 , wherein the fluid containing sleeve is arranged on the tubular portion in the container, and wherein the catheter is removable from the container without fluid leaking out of the container.

14. The catheter assembly according to claim 13 , wherein the fluid containing sleeve is non-removably coupled to the container.

15. The catheter assembly according to claim 13 , wherein the catheter is removable from the container along with the fluid containing sleeve.

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

17. The catheter assembly according to claim 1 , wherein the fluid containing sleeve comprises a gripping end which does not contain fluid and/or which allows a user to grip the fluid containing sleeve without the user's fingers becoming wetted by fluid.

18. 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.

19. The catheter assembly according to claim 18 , wherein the catheter is removable from the first compartment and insertable into the fluid containing sleeve of the second compartment.

20. The catheter assembly according to claim 19 , 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.

21. 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.
