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. An occlusion system comprising:

a delivery catheter including an inner catheter and a core wire;

an occlusion device including an expandable portion, wherein the occlusion device is coupled to the corewire with an interference fitting, and the occlusion device is abutted against the inner catheter of the delivery catheter; and

a handle coupled with the delivery catheter, the handle comprising a release mechanism moveable from a first incremented position having a first labeled operation to a second incremented position having a second labeled operation, the first and second labeled operations each referring to an operation in removing the occlusion device from the delivery catheter, and wherein movement of the release mechanism from the first incremented position to the second incremented position causes;

an expandable portion of the occlusion device to expand; and

a corewire to withdraw from the expanded occlusion device to fully disengage the expanded occlusion device from the delivery catheter;

wherein the inner catheter provides a counterforce against the occlusion device to decouple the interference fitting when the corewire is withdrawn from the expanded occlusion device to fully disengage the expanded occlusion device from the delivery catheter.

2. The occlusion system of claim 1, wherein the release mechanism is movable from an initial position to the first incremented position.

3. The occlusion system of claim 2, wherein movement of the release mechanism from the initial position to the first incremented position causes an outer catheter of the delivery catheter to withdraw and expose the expandable portion of the occlusion device.

4. The occlusion system of claim 1, wherein the release mechanism comprises a thumbwheel.

5. The occlusion system of claim 4, wherein the thumbwheel is rotatable in a proximal direction.

6. The occlusion system of claim 5, further comprising arrows on the handle pointing in the proximal direction.

7. The occlusion system of claim 1, further comprising a safety mechanism which when activated allows the release mechanism to move from the first incremented position to the second incremented position.

8. The occlusion system of claim 7, wherein the safety mechanism comprises a button.

9. The occlusion system of claim 1, wherein the occlusion device comprises an inner device member coupled with the expandable portion.

10. The occlusion system of claim 9, wherein the inner device member is an inner coil, and the expandable portion is an outer coil.

11. The occlusion system of claim 9, further comprising fibers coupled with the inner device member.

12. The occlusion system of claim 1, wherein movement of the release mechanism from the first incremented position to the second incremented position causes the corewire to withdraw from the frictional interference fitting with the expanded sterilization device without rotating the delivery catheter.

13. The occlusion system of claim 1, wherein the occlusion device comprise an atraumatic distal tip.

14. The occlusion system of claim 1, wherein:

the delivery catheter further comprises an outer catheter;

movement of the release mechanism from the initial position to the first incremented position causes the outer catheter of the delivery catheter to withdraw and expose the expandable portion of the occlusion device.
