Abstract

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

Claims

1. A method for accessing a cervical canal adjacent to a uterine cavity comprising:

inflating a first balloon attached at a first end to a first catheter;

translating a second catheter radially inside in the first catheter, wherein the first balloon is attached at a second end to the second catheter;

inflating a second balloon within the first balloon; and

dilating the cervical canal when inflating the second balloon.

2. The method in claim 1, wherein first balloon comprises an everting balloon and the second balloon comprises a dilating balloon;

further comprising tearing the everting balloon, wherein the tearing comprises inflating the dilating balloon when dilating the cervical canal adjacent to the uterine cavity.

3. The method of claim 1, wherein the first balloon comprises an everting balloon, and further comprising tearing the everting balloon with a mechanical instrument within the first catheter.

4. The method of claim 1, further comprising tearing the first balloon, wherein the tearing comprises the inflating of the second balloon within the first balloon.

5. The method of claim 1, wherein the dilating comprises dilating the cervical canal adjacent to the uterine cavity.

6. A method for accessing a cervical canal comprising:

inflating a first balloon attached at a first end to a first catheter;

translating a second catheter radially inside in the first catheter, wherein the first balloon is attached at a second end to the second catheter; and

tearing the first balloon.

7. The method of claim 6, further comprising inflating a second balloon within the first balloon;

and dilating the cervical canal when inflating the second balloon.

8. The method of claim 6, further comprising everting the first balloon in the cervical canal.

9. A system for accessing a cervical canal adjacent to a uterine cavity comprising:

a first catheter;

a second catheter radially inside in the first catheter, wherein the second catheter is translatable with respect to the first catheter;

a first balloon attached at a first end to the first catheter, and wherein the first balloon is attached at a second end to the second catheter; and

a second balloon attached to the second catheter;

wherein the second balloon is at least partially within the first balloon.

10. The system in claim 9, wherein the second balloon is configured to inflate within the first balloon and tear the first balloon.

11. The system in claim 10, wherein the first balloon comprises an everting balloon and the second balloon comprises a dilating balloon.

12. The system in claim 9, wherein the first balloon comprises an intention tear line, and wherein the intention line is configured to tear.

13. The system in claim 12, wherein the intention line in the first balloon comprises a mechanical indentation or seam.

14. The system in claim 9, wherein the first catheter comprises a mechanical instrument configured to tear the first balloon.

15. The system in claim 14, wherein the mechanical instrument is on the first catheter.

16. The system in claim 14, wherein the mechanical instrument is within the first catheter.

17. The system in claim 16, wherein the mechanical instrument is configured to activate upon full eversion and inflation of the dilating balloon.

18. The system in claim 10, wherein the second catheter comprises a sharp implement for tearing the eversion balloon, and wherein the sharp implement is configured to become active upon full eversion and inflation of the dilating balloon.

19. The system in claim 10, wherein the second catheter is configured to disengage the eversion balloon at the distal end of the second catheter upon inflating the dilating balloon.

20. The system in claim 10, wherein the eversion balloon comprises an eversion balloon material, and wherein a molecular structure of the eversion balloon material has an increased longitudinal axial orientation to promote a longitudinal break when the eversion balloon tears.
