Abstract

An everting balloon system is disclosed that can be used for the placement of an IUD within the uterine cavity of a female patient. The everting balloon system with IUD can be used to access a uterine cavity at specific locations in the fundus. A one-handed IUD delivery system for placement with an everting catheter is disclosed. An IUD loading system for placement within an everting catheter is disclosed. The everting catheter with an IUD can simplify the process of IUD placement within the uterine cavity.

Claims (31)

1. A system for delivering a device into the reproductive tract of a female comprising:

a first catheter having a lumen and a distal lumen port, wherein the first catheter has a retracted configuration and an extended configuration;

an everting balloon attached to the first catheter, wherein at least a length of the everting balloon extends past a distal end of the first catheter when the first catheter is in the extended configuration;

a second catheter slidably located in the first catheter;

an IUD in the second catheter; and

a third catheter radially outside of the first catheter.

2. The system of claim 1 , further comprising an irrigant configured to flow through the first catheter.

3. The system of claim 2 , wherein the irrigant comprises a therapeutic agent.

4. The system of claim 3 , wherein the therapeutic agent comprises a cytotoxic agent.

5. The system of claim 4 , wherein the therapeutic agent comprises an anticoagulant.

6. The system of claim 5 , wherein the anticoagulant comprises heparin.

7. The system of claim 4 , wherein the therapeutic agent comprises a sclerosing agent.

8. The system of claim 2 , wherein the irrigant comprises a medication.

9. The system of claim 8 , wherein the medication comprises an anesthetic agent.

10. The system of claim 9 , wherein the anesthetic agent comprises a local anesthetic.

11. The system of claim 10 , wherein the local anesthetic comprises lidocaine.

12. The system of claim 2 , wherein the irrigant comprises an analgesic agent.

13. The system of claim 1 , wherein the everting balloon is attached at a first end of the everting balloon to the third catheter, and wherein a second end of the everting balloon is attached to the first catheter.

14. A system for delivering a device into the reproductive tract of a female comprising:

a first catheter having a lumen and a distal lumen port, wherein the first catheter has a retracted configuration and an extended configuration;

an everting balloon attached to the first catheter, wherein at least a length of the everting balloon extends past a distal end of the first catheter when the first catheter is in the extended configuration;

a second catheter slidably located in the first catheter;

an IUD in the second catheter; and

a distal closure tip, wherein the distal closure tip is attached to the everting balloon,

wherein the distal closure tip comprises a pressure releasing element.

15. The system of claim 14 , further comprising an irrigant configured to flow through the first catheter.

16. The system of claim 15 , wherein the irrigant comprises a medication.

17. The system of claim 16 , wherein the medication comprises an anesthetic agent.

18. The system of claim 15 , wherein the irrigant comprises an analgesic agent.

19. The system of claim 15 , wherein the irrigant comprises a therapeutic agent.

20. The system of claim 14 , wherein the distal closure tip is configured to detach the everting balloon from the first catheter and the second catheter.
