System and method for occluding a reproductive body lumen
An occluding system is provided that can include a first occluding device (e.g., secondary occluder) and a second occluding device (e.g., primary occluder). Providing two devices can better promote effective occlusion within the body lumen and facilitate advantageous occlusion stages, such as initial and long-term occlusion stages. In various embodiments, the two occluding devices are in operative communication with one another, such that the second occluding device is adapted to couple with or slide along a tail portion of the first occluding device.
1. A system for occluding a body lumen comprising:
only two occlusion devices, the two occlusion devices including a proximal occlusion device and a distal occlusion device, wherein the distal occlusion device comprises an expandable tubular member and an inner lumen within the expandable tubular member;
a flexible and bunchable tail member that extends proximally from the distal occlusion device, and the proximal occlusion device is coupled to the tail member;
wherein the distal occlusion device and the proximal occlusion device are coupled together only with the flexible and bunchable tail member extending between the distal occlusion device and the proximal occlusion device.
2. The system of claim 1 , wherein the tail member comprises a polymer.
3. The system of claim 1 , wherein the proximal occlusion device surrounds the tail member.
4. The system of claim 1 , wherein the distal occlusion device is self-expandable.
5. The system of claim 4 , wherein a cross-section of the inner lumen expands as the expandable tubular member self-expands from a contracted state to an expanded state.
6. The system of claim 1 , wherein the distal occlusion device comprises an outer coil and an inner coil.
7. The system of claim 1 , wherein the distal occlusion device comprises fibers within the tubular member.
8. The system of claim 1 , wherein the proximal occlusion device is expandable.
9. The system of claim 8 , wherein the proximal occlusion device is self-expandable.
10. The system of claim 9 , wherein the proximal occlusion device is a plug.
11. The system of claim 10 , wherein the plug comprises permeable open cell segments.
12. The system of claim 1 , wherein both the proximal occlusion device and the distal occlusion device are self-expandable.
13. The system of claim 1 , wherein the distal occlusion device comprises fibers to support tissue ingrowth for permanent occlusion of the body lumen, and the proximal occlusion device is a polymer plug that provides immediate occlusion of the body lumen.
14. A system for occluding a body lumen comprising:
only two occlusion devices, the two occlusion devices including a proximal occlusion device and a distal occlusion device, wherein the distal occlusion device comprises a plurality of self-expanding leg segments emanating from a central apex;
a flexible and bunchable tail member that extends proximally from the distal occlusion device, and the proximal occlusion device is coupled to the tail member;
wherein the distal occlusion device and the proximal occlusion device are coupled together only with the flexible and bunchable tail member extending between the distal occlusion device and the proximal occlusion device.
15. The system of claim 14 , wherein the distal occlusion device comprises fibers.
16. The system of claim 14 , wherein the proximal occlusion device comprises a plug.
17. The system of claim 14 , wherein the distal occlusion device is self-expandable.
