Abstract

Catheter assemblies including a catheter and a liquid.

First claim

What is claimed is:

1. A catheter assembly comprising:
a urinary catheter comprising a shaft with a proximal end portion and a distal end portion, the shaft having a hydrophilic surface;
a collapsible sleeve defining a compartment that contains at least a portion of the catheter shaft, a distal end portion of the sleeve being attached to the distal portion of the urinary catheter;
a wetting fluid located within the compartment of the sleeve;
an introducer located at a proximal end of the sleeve, wherein the introducer includes a proximal introducer tip, an introducer distal portion, and a flange located between the proximal introducer tip and introducer distal portion, the collapsible sleeve being attached to the introducer distal portion;
a removable cap covering the introducer, wherein the cap defines a cavity that receives the introducer tip;
the cavity including a cavity proximal compartment and a cavity distal compartment that is wider than the cavity proximal compartment and is located adjacent to the cavity proximal compartment, wherein the cavity distal compartment is configured to receive a flange located at a distal end of the introducer tip; and
an absorbent material located in the cavity that absorbs fluid leaking from the sleeve.

2. The catheter assembly of claim 1 , wherein the absorbent material surrounds at least a portion of the introducer tip.

3. The catheter assembly of claim 2 , wherein the cavity is defined by an internal surface of the cap and the absorbent material is located on the internal surface of the cap.

4. The catheter assembly of claim 3 , wherein the absorbent material covers at least a portion of the internal surface defining the cavity proximal compartment.

5. The catheter assembly of claim 4 , wherein the absorbent material covers the entire internal surface defining the cavity proximal compartment.

6. The catheter assembly of claim 5 , wherein the absorbent material comprises an inner surface defining an inner cavity shaped to receive the introducer tip.

7. The catheter assembly of claim 6 , wherein the inner surface is commensurate to the size and shape of the introducer tip.

8. The catheter assembly of claim 5 , wherein the absorbent material comprises a deformable material configured to contact and conform to the shape of the introducer tip.

9. The catheter assembly of claim 2 , wherein the absorbent material comprises a ring on an internal surface of the cavity.

10. The catheter assembly of claim 1 , wherein the absorbent material is a sponge.

11. A leak resistant cap for a urinary catheter assembly comprising:
a closed proximal end and an open distal end;
an internal surface defining a cavity located at the open distal end, wherein the cavity is sized and configured to receive a proximal end of an introducer of the urinary catheter assembly and the urinary catheter assembly having a wetting liquid;
the cavity including a cavity proximal compartment and a cavity distal compartment that is wider than the cavity proximal compartment and is located adjacent to the cavity proximal compartment, wherein the cavity distal compartment is configured to receive a flange of the urinary catheter assembly; and
an absorbent material located in the cavity proximal compartment, wherein the absorbent material absorbs the wetting liquid leaking from the urinary catheter assembly, thereby preventing leakage from the urinary catheter assembly.

12. The cap of claim 11 , wherein the absorbent material surrounds at least a portion of the proximal end of the urinary catheter assembly.

13. The cap of claim 12 , wherein the absorbent material is located on the internal surface of the cap.

14. The cap of claim 13 , wherein the absorbent material covers at least a portion of the internal surface defining the cavity proximal compartment.

15. The cap of claim 14 , wherein the absorbent material covers the entire internal surface defining the cavity proximal compartment.

16. The cap of claim 15 , wherein the absorbent material comprises an inner surface defining an inner cavity shaped to receive the proximal end of the catheter assembly.

17. The cap of claim 16 , wherein the inner surface is commensurate to the size and shape of the proximal end of the catheter assembly.

18. The cap of claim 15 , wherein the absorbent material comprises a deformable material configured to contact and conform to the shape of the proximal end of the catheter assembly.

19. A catheter assembly comprising:
a urinary catheter comprising a shaft with a proximal end portion and a distal end portion, the shaft having a hydrophilic surface;
a collapsible sleeve defining a compartment that contains at least a portion of the catheter shaft, a distal end portion of the sleeve being attached to the distal portion of the urinary catheter;
a wetting fluid located within the compartment of the sleeve;
an introducer comprising a tip and located at a proximal end of the sleeve;
a removable cap covering the introducer, wherein the cap defines a cavity that receives the introducer tip; and
a superabsorbent material located in the cavity configured to absorb fluid leaking from the sleeve.

20. A leak resistant cap for a urinary catheter assembly comprising:
a closed proximal end and an open distal end;
an internal surface defining a cavity located at the open distal end, wherein the cavity is sized and configured to receive a proximal end of an introducer of the urinary catheter assembly and the urinary catheter assembly having a wetting liquid; and
a superabsorbent material located in the cavity, wherein the superabsorbent material absorbs the wetting liquid leaking from the urinary catheter assembly, thereby preventing leakage from the urinary catheter assembly.
