Abstract

A protective catheter tip has a generally tubular body portion defining an interior cavity. The proximal end of a urinary catheter is at least partially received within the protective tip, with the protective tip being retained on the urinary catheter without the need for a sleeve connecting the protective tip and the catheter. The protective tip may include a projection received within a draining hole or eye at the proximal end of the catheter to retain the protective tip on the catheter. The protective tip may instead include one or more projections that apply a frictional force to an outer surface of the catheter to retain the protective tip on the catheter. The protective tip may instead be retained on the catheter by a tether extending between the protective tip and a distal end of the catheter. The protective tip may also include two separate or separable pieces.

Claims

1. A sleeveless urinary catheter assembly, comprising:

a urinary catheter including an eye; and

a protective tip comprising

a generally tubular body portion defining an interior cavity;

a proximal access end including one or more slits configured to allow the proximal access end to move between a generally closed condition and a generally open condition; and

at least one projection extending into the interior cavity of the body portion and at least partially received by the eye of the urinary catheter, wherein the at least one projection includes a substantially planar radial surface contacting the eye of the urinary catheter.

2. The sleeveless urinary catheter of claim 1, wherein the at least one projection includes an inclined surface at least partially received by the eye of the urinary catheter.

3. The sleeveless urinary catheter of claim 2, wherein the body portion extends between a distal end and a proximal end, and the inclined surface of the at least one projection faces the distal end.

4. The sleeveless urinary catheter of claim 3, wherein the radial surface faces the proximal end of the body portion.

5. The sleeveless urinary catheter of claim 1, wherein the at least one projection extends generally radially inwardly from the body portion.

6. The sleeveless urinary catheter of claim 1, wherein the at least one projection is integrally formed with the body portion.

7. The sleeveless urinary catheter of claim 1, wherein

the urinary catheter includes a second eye, and

the protective tip includes a second projection extending into the interior cavity of the body portion and at least partially received by the second eye of the urinary catheter.

8. The sleeveless urinary catheter of claim 7, wherein

the body portion extends between a distal end and a proximal end,

each projection includes an inclined surface facing the distal end of the body portion,

the second projection includes a radial surface, and

the radial surface of each projection faces the proximal end of the body portion.

9. The sleeveless urinary catheter of claim 1, wherein

the at least one projection includes a base portion associated with the body portion and an end portion positioned radially inwardly of the base portion,

the base portion is wider than the end portion, and

only the end portion of the at least one projection is received by the eye of the urinary catheter.

10. The sleeveless urinary catheter of claim 1, wherein the at least one projection is configured to be at least partially received by the eye of the urinary catheter without the at least one projection extending proximally or distally of the eye within the urinary catheter.

11. A sleeveless urinary catheter assembly, comprising:

a urinary catheter including an eye; and

a protective tip comprising

a generally tubular body portion defining an interior cavity;

a proximal access end including one or more slits configured to allow the proximal access end to move between a generally closed condition and a generally open condition; and

at least one projection extending into the interior cavity of the body portion and at least partially received by the eye of the urinary catheter, wherein

the at least one projection includes a base portion associated with the body portion and an end portion positioned radially inwardly of the base portion,

the base portion is wider than the end portion, and

only the end portion of the at least one projection is received by the eye of the urinary catheter.

12. The sleeveless urinary catheter of claim 11, wherein the at least one projection includes an inclined surface at least partially received by the eye of the urinary catheter.

13. The sleeveless urinary catheter of claim 12, wherein the body portion extends between a distal end and a proximal end, and the inclined surface of the at least one projection faces the distal end.

14. The sleeveless urinary catheter of claim 13, wherein the at least one projection includes a radial surface facing the proximal end of the body portion.

15. The sleeveless urinary catheter of claim 11, wherein the at least one projection extends generally radially inwardly from the body portion.

16. The sleeveless urinary catheter of claim 11, wherein the at least one projection is integrally formed with the body portion.

17. The sleeveless urinary catheter of claim 11, wherein

the urinary catheter includes a second eye, and

the protective tip includes a second projection extending into the interior cavity of the body portion and at least partially received by the second eye of the urinary catheter.

18. The sleeveless urinary catheter of claim 17, wherein

the body portion extends between a distal end and a proximal end,

19. The sleeveless urinary catheter of claim 11, wherein the at least one projection is at least partially received by the eye of the urinary catheter without the at least one projection extending proximally or distally of the eye within the urinary catheter.

20. A sleeveless urinary catheter assembly, comprising:

a urinary catheter including an eye; and

a protective tip comprising

a generally tubular body portion defining an interior cavity;

a proximal access end including one or more slits configured to allow the proximal access end to move between a generally closed condition and a generally open condition; and

at least one projection extending into the interior cavity of the body portion and at least partially received by the eye of the urinary catheter without the at least one projection extending proximally or distally of the eye within the urinary catheter.

21. The sleeveless urinary catheter of claim 20, wherein the at least one projection includes an inclined surface at least partially received by the eye of the urinary catheter.
