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 medical device for a transcervical medical sterilization procedure, comprising:

an elongated catheter with a distal portion and a proximal portion;

a fallopian tube implant removably coupled to the distal portion;

a handle coupled to the proximal portion;

a rack within the handle, wherein the rack travels in a proximal direction within the handle and does not travel in a distal direction within the handle when the fallopian tube implant is coupled to the distal portion; and

a release mechanism on the handle and operably coupled with the rack, wherein the release mechanism and rack are movable from an initial position until the release mechanism and rack stop at a final incremented position to removably decouple the fallopian tube implant from the elongated catheter, and the handle includes an indicator that illuminates upon moving the release mechanism and rack to the final incremented position to indicate that the fallopian tube implant is decoupled from the elongated catheter

wherein the release mechanism comprises a thumbwheel that is rotatable from the initial position until the thumbwheel stops at the final incremented position.

2. The medical device of claim 1, wherein moving the release mechanism and rack to the final incremented position causes a core wire to withdraw from the fallopian tube implant.

3. The medical device of claim 2, further comprising an inner catheter within the elongated catheter, and the inner catheter buttresses against the fallopian tube implant while the core wire is withdrawn from the fallopian tube implant.

4. The medical device of claim 1, wherein the indicator is an LED light.

5. The medical device of claim 1, wherein the release mechanism and rack are movable from the initial position to a first incremented position and then to the final incremented position, and the handle additionally includes a first indicator that illuminates upon moving the release mechanism and rack to the first incremented position.

6. The medical device of claim 1, wherein the handle additionally includes a power source for illuminating the indicator.

7. The medical device of claim 1, wherein the handle additionally includes an audible indicator that makes an audible sound upon moving the release mechanism and rack to the final incremented position.

8. A medical device for a transcervical medical sterilization procedure, comprising:

an elongated catheter with a distal portion and a proximal portion;

a fallopian tube implant removably coupled to the distal portion;

a handle coupled to the proximal portion;

a rack within the handle, wherein the rack travels in a proximal direction within the handle and does not travel in a distal direction within the handle when the fallopian tube implant is coupled to the distal portion; and

a release mechanism on the handle and operably coupled with the rack, wherein the release mechanism and rack are movable from an initial position until the release mechanism and rack stop at a final incremented position to removably decouple the fallopian tube implant from the elongated catheter, and the handle includes an indicator that makes an audible sound upon moving the release mechanism and rack to the final incremented position to indicate that the fallopian tube implant is decoupled from the elongated catheter

wherein the release mechanism comprises a thumbwheel that is rotatable from the initial position until the thumbwheel stops at the final incremented position.

9. The medical device of claim 8, wherein moving the release mechanism and rack to the final incremented position causes a core wire to withdraw from the fallopian tube implant.

10. The medical device of claim 9, further comprising an inner catheter within the elongated catheter, and the inner catheter buttresses against the fallopian tube implant while the core wire is withdrawn from the fallopian tube implant.

11. The medical device of claim 8, wherein the indicator emits at least a single tone.

12. The medical device of claim 8, wherein the indicator emits a spoken voice.

13. A medical device for a transcervical medical sterilization procedure, comprising:

an elongated catheter with a distal portion and a proximal portion;

a fallopian tube implant removably coupled to the distal portion;

a handle coupled to the proximal portion;

a rack within the handle, wherein the rack travels in a proximal direction within the handle and does not travel in a distal direction within the handle when the fallopian tube implant is coupled to the distal portion; and

a release mechanism on the handle and operably coupled with the rack, wherein the release mechanism and rack are movable from an initial position until the release mechanism and rack stop at a final incremented position to removably decouple the fallopian tube implant from the elongated catheter, and the handle includes a wireless transmitter for transmitting a signal upon moving the release mechanism and rack to the final incremented position to indicate that the fallopian tube implant is decoupled from the elongated catheter

wherein the release mechanism comprises a thumbwheel that is rotatable from the initial position until the thumbwheel stops at the final incremented position.

14. The medical device of claim 13, wherein moving the release mechanism and rack to the final incremented position causes a core wire to withdraw from the fallopian tube implant.

15. The medical device of claim 14, further comprising an inner catheter within the elongated catheter, and the inner catheter buttresses against the fallopian tube implant while the core wire is withdrawn from the fallopian tube implant.

16. The medical device of claim 13, further comprising a separate instrument to receive the signal and trigger a visual or audible indicator.
