Apparatus and method for everting catheter for IUD delivery and placement in the uterine cavity
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.
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, wherein the length of the everting balloon that extends past the distal end of the first catheter comprises a check valve when the first catheter is in the extended configuration;
a second catheter slidably located in the first catheter;
a third catheter radially outside of the first catheter, wherein a first end of the everting balloon is attached to the third catheter, wherein a second end of the everting balloon is attached to the first catheter; and
an IUD in the second catheter.
2. The system of claim 1 , further comprising a pusher in the second catheter.
3. The system of claim 2 , wherein the pusher comprises a connection hub.
4. The system of claim 2 , wherein the pusher comprises an irrigation source.
5. The system of claim 2 , wherein the system is configured such that the pusher extends the IUD as the IUD is released from the second catheter concurrent with negative pressure being delivered within the everting balloon.
6. The system of claim 1 , wherein the system is configured to release the IUD concurrent with delivering negative pressure within the everting balloon.
7. The system of claim 1 , further comprising an irrigant, wherein the system is configured to deliver the irrigant through the second catheter concurrent with releasing the IUD from the second catheter.
8. The system of claim 1 , further comprising an irrigation source configured to deliver an irrigant through the second catheter.
9. 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;
a third catheter radially outside of the first catheter, wherein a first end of the everting balloon is attached to the third catheter, wherein a second end of the everting balloon is attached to the first catheter; and
an IUD, wherein the second catheter is configured to deliver the IUD.
10. The system of claim 9 , further comprising a pusher in the second catheter.
11. The system of claim 10 , wherein the pusher comprises a connection hub.
12. The system of claim 10 , wherein the pusher comprises an irrigation source.
13. The system of claim 10 , wherein the system is configured such that the pusher extends the IUD as the IUD is released from the second catheter concurrent with negative pressure being delivered within the everting balloon.
14. The system of claim 9 , wherein the system is configured to release the IUD concurrent with delivering negative pressure within the everting balloon.
15. The system of claim 9 , further comprising an irrigant, wherein the system is configured to deliver the irrigant through the second catheter concurrent with releasing the IUD from the second catheter.
16. The system of claim 9 , further comprising an irrigation source configured to deliver an irrigant through the second catheter.
