Abstract

The various embodiments of the present inventions provide stabilization devices and methods for use of the stabilization devices with minimally invasive gynecological procedures such as methods of preventing pregnancy by inserting intrafallopian contraceptive devices into the fallopian tubes.

Claims

1. A stabilization device, comprising:

a sleeve having a lumen extending between a proximal end and a distal end of the sleeve, the sleeve adapted to be inserted into a working channel of a hysteroscope;

a proximal seal at the proximal end of the sleeve through which a catheter can be advanced into the lumen and into the working channel of the hysteroscope, wherein the proximal seal comprises a duckbill valve; and

a distention valve fixed in place on the sleeve such that the distention valve is not movable along the sleeve, the distal end of the sleeve extends distally beyond the distention valve and a depth at which the distal end of the sleeve can be inserted into the working channel of the hysteroscope is determined by where the distention valve is fixed in place on the sleeve, wherein the distention valve includes a portion adapted to fit onto and form a seal around the working channel of the hysteroscope.

2. The stabilization device of claim 1, wherein the proximal seal comprises an O-ring.

3. The stabilization device of claim 1, wherein the proximal seal comprises a membrane.

4. The stabilization device of claim 1, wherein the proximal seal comprises a double membrane.

5. The stabilization device of claim 1, wherein the proximal seal comprises a hole seal.

6. The stabilization device of claim 1, wherein the distention valve is adjacent the proximal seal at the proximal end of the sleeve.

7. The stabilization device of claim 1, wherein the sleeve is sized and dimensioned to extend past a valve clamp of the working channel when the distention valve is fitted onto the working channel.

8. The stabilization device of claim 1, wherein the proximal seal is adapted to prevent backflow of fluid out of the stabilization device.

9. The stabilization device of claim 8, wherein the proximal seal is adapted to prevent backflow of fluid out of the stabilization device when the catheter is advanced into the lumen and into the working channel of the hysteroscope.

10. The stabilization device of claim 1, wherein the distal end of the sleeve is tapered.

11. The stabilization device of claim 1, wherein the distention valve is permanently fixed in place on the sleeve.

12. A kit, comprising:

a catheter for an intrafallopian contraceptive procedure; and

a stabilization device comprising;

a sleeve having a lumen extending longitudinally between a proximal end and a distal end of the sleeve, the sleeve adapted to be inserted into a working channel of a hysteroscope;

a proximal seal at the proximal end of the sleeve through which a catheter can be advanced into the lumen and into the working channel of the hysteroscope, wherein the proximal seal comprises a duckbill valve; and

a distention valve fixed in place on the sleeve such that the distention valve is not movable along the sleeve, the distal end of the sleeve extends distally beyond the distention valve and a depth at which the distal end of the sleeve can be inserted into the working channel of the hysteroscope is determined by where the distention valve is fixed in place on the sleeve, wherein the distention valve includes a portion adapted to fit onto and form a seal around the working channel of the hysteroscope.

13. The kit of claim 12, wherein the proximal seal comprises an O-ring.

14. The kit of claim 12, wherein the proximal seal comprises a membrane.

15. The kit of claim 12, wherein the proximal seal comprises a double membrane.

16. The kit of claim 12, wherein the proximal seal comprises a hole seal.

17. The stabilization device of claim 12, wherein the proximal seal is adapted to prevent backflow of fluid out of the stabilization device.

18. The stabilization device of claim 17, wherein the proximal seal is adapted to prevent backflow of fluid out of the stabilization device when the catheter is advanced into the lumen and into the working channel of the hysteroscope.

19. The kit of claim 12, wherein the distention valve is adjacent the proximal seal at the proximal end of the sleeve.

20. The kit of claim 12, wherein the sleeve is sized and dimensioned to extend past a valve clamp of the working channel when the distention valve is fitted onto the working channel.

21. The kit of claim 12, wherein the distal end of the sleeve is tapered.

22. The kit of claim 12, wherein the distention valve is permanently fixed in place on the sleeve.
