Abstract

A catheter device for non-surgical entry into a uterus, includes a tubular body having a lumen extending from a first end thereof to a second end thereof, the lumen having an external opening adjacent to or at the first end for dispensing a diagnostic fluid into the uterus. An elongated balloon is disposed distally on the tubular body for insertion into the cervical canal of the uterus, the balloon having opposing portions which occlude opposing openings of the canal.

Claims

1. A catheter device comprising:

a tubular body having a lumen extending from a first end thereof to a second end thereof, the lumen having an external opening for dispensing a diagnostic fluid;

an elongated balloon disposed distally on the tubular body for insertion into a canal of a body, the balloon having opposing portions which occlude openings of the canal when inflated; and

an inflation sleeve slidably disposed over the tubular body, the sleeve being moveable over the elongated balloon to inflate the opposing portions of the balloon.

2. The catheter device according to claim 1, wherein the tubular body is flexible.

3. The catheter device according to claim 1, wherein the inflation sleeve is semi-rigid.

4. The catheter device according to claim 1, wherein the portions of the balloon define a double balloon structure when the balloon is inserted in the canal.

5. The catheter device according to claim 1, wherein the balloon is made from an elastomeric material.

6. The catheter device according to claim 1, wherein the tubular body is made from a polyurethane material.

7. The catheter device according to claim 1, further comprising a stylet removeably inserted into the lumen of the tubular body through the second end thereof.

8. The catheter device according to claim 1, wherein the external opening of the tubular body is adjacent the first end thereof.

9. The catheter device according to claim 1, wherein the external opening of the tubular body is at the first end thereof.

10. A catheter device for non-surgical entry into a uterus to dispense a diagnostic fluid therein, the catheter comprising:

a tubular body having a lumen extending from a first end thereof to a second end thereof, the lumen having an external opening for dispensing the diagnostic fluid into the uterus;

an elongated balloon disposed distally on the tubular body for insertion into the cervical canal of the uterus, the balloon having opposing portions which occlude openings of the canal; and

an inflation sleeve slidably disposed over the tubular body, the sleeve being moveable over the elongated balloon to inflate the opposite portions of the balloon.

11. The catheter device according to claim 10, wherein the body is flexible.

12. The catheter device according to claim 10, wherein the inflation sleeve is semi-rigid.

13. The catheter device according to claim 10, wherein the portions of the balloon define a double balloon structure when the balloon is inserted in the cervical canal.

14. The catheter device according to claim 10, wherein the balloon is made from an elastomeric material.

15. The catheter device according to claim 10, wherein the tubular body is made from a polyurethane material.

16. The catheter device according to claim 10, further comprising a stylet removeably inserted into the lumen of the tubular body through the second end thereof.

17. A method for non-surgically entering a uterus to dispense a diagnostic fluid therein, the method comprising the steps of:

providing a catheter comprising a tubular body having a lumen extending from a first end thereof to a second end thereof, an elongated balloon disposed distally on the tubular body, and an inflation sleeve slidably disposed over the tubular body;

inserting the first end of the tubular body through the cervical canal of the uterus so that the elongated balloon is position within the canal with opposing portions of the balloon adjacent openings of the canal;

sliding the inflation sleeve over a section of one of the opposing portions of the balloon thereby inflating the opposing portions of the balloon to occlude the openings of the canal; and

dispensing the diagnostic fluid through the lumen of the catheter into the uterus.

18. The method according to claim 17, wherein the catheter further comprises a stylet removeably inserted into the lumen of the tubular body through the second end thereof and further comprising the step of removing the stylet from the tubular body of the catheter prior to the dispensing step.

19. The method according to claim 17, further comprising the step of proximally sliding the inflation sleeve off the section of the balloon portion to deflate the opposing balloon portions.

20. The method according to claim 19, further comprising the step of withdrawing the first end of the tubular body through the cervical canal of the uterus.
