Indwelling urinary catheterization assembly

1. An indwelling urinary catheter assembly comprising:

an indwelling catheter comprising a first end having a urine inlet, a second end having a urine outlet, a takeoff port having a port bore, an expander, and a urethra insertable portion;

wherein the urine inlet and urine outlet are in fluid communication with one another and wherein the port bore and the expander are in fluid communication with one another;

a pliable sheath comprising a lumen, wherein the sheath encloses at least a portion of the insertable portion; and

an introducer attached to the sheath, wherein the introducer is dimensioned and configured to enclose and support the first end when in an initial position, the introducer slidingly receives the insertable portion during insertion of the insertable portion into the urethra of a patient, wherein the introducer is dimensioned and configured to be partially inserted into the urethra of a patient, and the introducer together with the sheath encloses all of the urethra-insertable portion when in the initial position;

wherein the sheath further comprises a terminus directly coupled to an area of the catheter that includes a portion of the takeoff port; and

wherein the terminus comprises a collar having at least one vent in fluid communication with the lumen and an environment outside the sheath, the vent being dimensioned and configured to relieve a pressure build-up within the sheath.

2. The indwelling catheter assembly of claim 1 , wherein the terminus sealingly engages the catheter at an attachment point at the area including the portion of the takeoff port.

3. The catheter assembly of claim 1 , further comprising a non-insertable portion, wherein at least part of the non-insertable portion comprises an uncovered region of the indwelling catheter outside the sheath.

4. The catheter assembly of claim 3 further comprising a urine receptacle coupled to the non-insertable portion of the catheter.

5. The indwelling catheter assembly of claim 1 , wherein the sheath is removably attached to the indwelling catheter.

6. An catheterization kit comprising:

the indwelling urinary catheter assembly of claim 1 ; and

a sanitary wrapper enclosing the assembly.

7. The kit of claim 6 consisting essentially of the following items:

the indwelling urinary catheter assembly;

at least one antiseptic swab;

disposable gloves;

a urine specimen container; and

a tray capable of holding the catheter assembly, swab(s), gloves, and specimen container,

wherein the tray is also capable of serving as a urine receptacle; and a

sanitary wrapper enclosing the items.

8. The kit of claim 7 excluding one or more drapes.

9. The kit of claim 8 excluding forceps.

10. The kit of claim 9 excluding antiseptic liquid.

11. The indwelling catheter assembly of claim 1 , wherein the indwelling catheter has a total length from the first end to the second end, wherein the indwelling catheter is prelubricated from the first end to a point located at ⅓ rd the length from the first end.

12. The indwelling catheter assembly of claim 1 , wherein the introducer comprises a lubricant reservoir operable to lubricate the insertable portion.

13. The indwelling catheter assembly of claim 1 , further comprising a fixation tab coupled to the collar.

14. An indwelling urinary catheter assembly comprising:

an indwelling catheter comprising a first end having a urine inlet, a second end having a urine outlet, a takeoff port between the first end and second end, an expander, and a urethra insertable portion;

wherein the takeoff port includes a port bore in fluid communication with the expander;

wherein the urine inlet and urine outlet are in fluid communication;

a pliable sheath comprising a lumen, wherein the sheath encloses at least a portion of the insertable portion; and

an introducer attached to the sheath opposite the terminus, wherein the introducer is dimensioned and configured to enclose and support the first end when in an initial position, the introducer slidingly receives the insertable portion during insertion of the insertable portion into the urethra of a patient, wherein the introducer is dimensioned and configured to be partially inserted into the urethra of a patient, and the introducer together with the sheath encloses all of the urethra-insertable portion when in the initial position;

wherein the sheath further comprises a terminus directly coupled to an area of the catheter that includes a portion of the takeoff port; and

wherein the terminus comprises a collar having at least one vent in fluid communication with the lumen and an environment outside the sheath, the vent being dimensioned and configured to relieve a pressure build-up within the sheath.

15. The indwelling catheter assembly of claim 14 , wherein the sheath is removably attached to the indwelling catheter.

16. The indwelling catheter assembly of claim 15 , wherein the collar is dimensioned and configured to removably attach to the introducer.

17. The indwelling catheter assembly of claim 14 , wherein the introducer further comprises a fixation tab adapted to couple the catheter to a patient.

18. A catheterization kit comprising:

the indwelling urinary catheter assembly of claim 14 ; and

a sanitary wrapper enclosing the assembly.

19. An indwelling urinary catheter assembly comprising:

an indwelling catheter comprising a first end having a urine inlet, a second end having a urine outlet, a takeoff port between the first end and second end, an expander, and a urethra insertable portion;

wherein the takeoff port includes a port bore in fluid communication with the expander;

wherein the urine inlet and urine outlet are in fluid communication;

a pliable sheath comprising a lumen and a terminus, wherein the sheath encloses part of the insertable portion, and wherein the terminus is directly coupled to each of an area of the catheter that includes a portion of the takeoff port, the indwelling catheter between the takeoff port and first end, and the indwelling catheter between the takeoff port and the second end, wherein the terminus further comprises a collar having at least one vent in fluid communication with the lumen and an environment outside the sheath, the vent being dimensioned and configured to relieve a pressure build-up within the sheath; and

an introducer attached to the sheath opposite the terminus, wherein the introducer is dimensioned and configured to enclose and support the first end when in an initial position, the introducer slidingly receives the insertable portion during insertion of the insertable portion into the urethra of a patient, wherein the introducer is dimensioned and configured to be partially inserted into the urethra of a patient, and the introducer together with the sheath encloses all of the urethra-insertable portion when in the initial position.
