Abstract

A balloon catheter with improved balloon orientation includes a head, a catheter shaft extending from the head, and a balloon disposed on the catheter shaft opposite the head. The balloon of the present invention has an orientation such that the inflated width of the balloon is at least about 1.3 times the length of the balloon.

Claims

1. A catheter having an interior and an exterior, the catheter comprising:

a means for expansion having a proximal end, a distal end, a length dimension and a width dimension;

a shaft including a distal end, a first lumen configured for fluid communication with a body cavity, and a second lumen configured for communication with the means for expansion; and

wherein the width dimension of the means for expansion is greater than the length dimension of the means for expansion when the means for expansion is expanded.

2. The catheter of claim 1, wherein the means for expansion has a width dimension to length dimension ratio of at least about 1.3 to 1 when the means for expansion is expanded.

3. The catheter of claim 1, wherein the means for expansion has a width dimension to length dimension ratio of at least about 1.4 to 1 when the means for expansion is expanded.

4. The catheter of claim 1, wherein the means for expansion has a width dimension to length dimension ratio of at least about 1.5 to 1 when the means for expansion is expanded.

5. The catheter of claim 1 wherein the means for expansion is a balloon, an expandable sleeve, or an inflatable member.

6. The catheter of claim 1, wherein the catheter further comprises a tip attached to the distal end of the shaft, the tip having a proximal end, a distal end, and an interior defining a passageway;

and

wherein the proximal end of the means for expansion is attached to the shaft and the distal end of the means for expansion is attached to the interior of the tip.

7. The catheter of claim 1, wherein the catheter further comprises a tip attached to the shaft, the tip having a proximal end, a distal end, and an interior defining a passageway;

and

wherein the proximal end of the means for expansion is attached to the shaft and the distal end of the means for expansion is integrally formed with the tip.

8. The catheter of claim 6, wherein the means for expansion extends distally from the distal end of the tip, and then circumscribes the distal end of the tip.

9. The catheter of claim 7, wherein the means for expansion extends distally from the distal end of the catheter, and then circumscribes the distal end of the catheter.

10. The catheter of claim 1, wherein the means for expansion comprises an elastomeric material.

11. A catheter comprising:

a head having at least two openings through which fluid may be passed;

a catheter shaft extending from the head, the catheter shaft having a first and second lumen, each of the lumens being in communication with at least one of the two openings, the catheter shaft further having an interior and an exterior; and

a means for expansion having a first end attached to the catheter shaft and a second end attached to the catheter shaft, wherein the means for expansion has a width dimension at least about 1.4 times greater than the length dimension of the means for expansion when the means for expansion is expanded.

12. The catheter of claim 11, wherein the first end of the means for expansion is attached to the exterior of the catheter shaft, and the second end of the means for expansion is attached to the interior of the catheter shaft.

13. The catheter of claim 11, wherein the first end of the means for expansion is attached to the exterior of the catheter shaft, and the second end of the means for expansion is attached to the exterior of the catheter shaft.

14. The catheter of claim 11, wherein the catheter shaft further comprises

a distal end;

and

a tip attached to the distal end of the catheter shaft.

15. The catheter of claim 14, wherein the first end of the means for expansion is attached to the exterior of the catheter shaft, and wherein the second end of the means for expansion is attached to the interior of the tip.

16. The catheter of claim 11, wherein the head has a plurality of valves configured for selectively controlling fluid flow through the catheter.

17. A catheter comprising:

an elongate shaft having at least one lumen extending longitudinally therethrough, a distal end and a width dimension; and

an expandable balloon, said balloon having a length dimension and a width dimension;

wherein the width dimension of the balloon is larger than the length dimension of the balloon when the balloon is expanded.

18. The catheter of claim 17, wherein the width dimension of the balloon is at least about 1.4 times larger than the length dimension of the balloon when the balloon is expanded.

19. The catheter of claim 17, wherein the width dimension of the balloon is at least about 1.45 times larger than the length dimension of the balloon when the balloon is expanded.

20. The catheter of claim 17, wherein the width dimension of the balloon is at least about 1.5 times larger than the length dimension of the balloon when the balloon is expanded.

21. The catheter of claim 17, wherein the shaft further comprises

a distal end;

and

a tip attached to the distal end of the shaft.

22. The catheter of claim 21 further comprising a head;

wherein the balloon is located between the head and the distal tip of the catheter.

23. The catheter of claim 17, wherein the balloon has at least one cuff, and wherein one of the cuffs is located at or near the distal end of the catheter.

24. The catheter of claim 17, wherein the balloon has at least one cuff, and wherein at least one of the cuffs is attached to the interior of the catheter.

25. A balloon catheter configured for placement through a stoma into a body cavity so that the catheter is maintained in the stoma, the catheter comprising:

a head having at least one opening through which a fluid may be introduced;

a catheter shaft extending from the head to a distal end the catheter shaft forming a passageway, said passageway having an interior; and

an expandable member attached to the catheter shaft about the passageway so as to form a balloon, the balloon being in collapsed state when not expanded;

wherein the balloon has a first end, a second end, a length dimension and a width dimension; and

wherein the balloon extends radially outwardly from the catheter shaft when expanded, such that the width of the balloon is at least about 1.3 times the length of the balloon when expanded.

26. The balloon catheter of claim 25, wherein a first end of the balloon is attached to the catheter shaft so as to form a proximal cuff of the balloon, and wherein a second end of the balloon is attached to the catheter shaft so as to form a distal cuff of the balloon.

27. The balloon catheter of claim 25, wherein the distal end of the balloon is attached to the distal end of the catheter and wherein the distal end of the balloon defines a portion of the passageway through the catheter shaft.

28. The balloon catheter of claim 25, wherein the catheter shaft comprises a tip attached to the distal end of the catheter shaft, opposite the head.
