Abstract

The invention relates to a Foley-type catheter constructed to prevent a retention balloon of the Foley catheter from cuffing. The retention balloon has a length of less than or equal to 0.40 inches. A kit, including the cuff-resistant Foley catheter and a syringe containing about 6 cc of water, can be provided.

Claims

1. A catheter comprising:

a) a catheter shaft defining a first lumen and a second lumen, the first lumen being in fluid communication with an opening located at a distal end of the catheter shaft; and

b) an inflatable silicone balloon arranged in fluid communication with the second lumen of the catheter shaft, the inflatable balloon having a first end attached to the catheter shaft and a second end attached to the catheter shaft, the inflatable balloon having a length defined between the first end and the second end, the length of the balloon being about 0.40 inches or less.

2. The catheter of claim 1, wherein the first lumen is a fluid lumen sized to convey fluid from a patient'"'"'s bladder through the catheter shaft, and wherein the second lumen is a capillary lumen sized to transport fluid to and from the inflatable balloon to inflate and deflate the balloon.

3. The catheter of claim 1, wherein the inflatable balloon has a diameter of about 0.80 inches to 1.1 inches when inflated.

4. The catheter of claim 1, wherein the inflatable balloon has a ring-shaped configuration when inflated.

5. The catheter of claim 4, wherein the balloon has a diameter, the balloon having a diameter to length ratio of about 1.0 to 3.0 when inflated.

6. The catheter of claim 1, wherein the inflatable balloon defines a balloon cavity, the balloon cavity being configured to receive less than about 7 cc of fluid.

7. The catheter of claim 6, wherein the balloon cavity is configured to receive about 6 cc of fluid.

8. The catheter of claim 1, wherein a centerline of the opening of the catheter shaft is located no more than 1.0 inches from the first end of the inflatable balloon.

9. The catheter of claim 8, wherein a centerline of the opening of the catheter shaft is located no more than 0.80 inches from the first end of the inflatable balloon.

10. The catheter of claim 1, wherein the inflatable balloon is a multi-layered inflatable balloon including a first balloon layer and a second sheath layer.

11. The catheter of claim 1, wherein the inflatable balloon includes ribs.

12. The catheter of claim 11, wherein the ribs extend in a direction generally parallel to the catheter shaft.

13. The catheter of claim 11, wherein the catheter shaft includes grooves sized to receive the ribs.

14. The catheter of claim 10, wherein the inflatable balloon includes ribs formed in the balloon layer, the ribs extending in a direction generally parallel to the catheter shaft, the ribs being sized to fit within grooves formed in the catheter shaft.

15. A kit, comprising:

a) a catheter including;

i) a catheter shaft defining a fluid lumen and a capillary lumen;

ii) a balloon in fluid communication with the capillary lumen;

iii) an end piece having first and second ports in fluid communication with the fluid and capillary lumens, respectively;

b) a syringe pre-filled with less than about 7 cc of fluid, the syringe being constructed to inject the fluid into the second port of the end piece to inflate the balloon.

16. The kit of claim 15, wherein the balloon has length defined between a first end and a second end, the length of the balloon being about 0.40 inches or less.

17. The kit of claim 15, wherein the inflatable balloon defines a balloon cavity, the balloon cavity being configured to receive less than about 7 cc of fluid.

18. The kit of claim 17, wherein the balloon cavity is configured to receive about 6 cc of fluid.

19. A method of manufacturing a catheter, the method comprising the steps of:

a) providing a catheter shaft; and

b) attaching an inflatable retention balloon to the catheter shaft at a first end of the balloon and at a second end of the balloon such that the balloon has a length between the first end and second end of about 0.40 inches or less.

20. The method of claim 19, wherein the step of attaching the inflatable retention balloon includes attaching a retention balloon having a diameter of about 0.80 inches to 1.1 inches when inflated.
