System and method for occluding a reproductive body lumen
View Patent ↗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 method of occluding a patient's body lumen, comprising:
advancing a delivery catheter tool at least partially receiving a first occluding device therein to a location within a fallopian tube of a patient, wherein the first occluding device includes a tail member, and a first transverse configuration within the delivery catheter tool;
deploying the first occluding device from the delivery catheter tool and within the fallopian tube, wherein the deployed first occluding device comprises a radially expanded configuration with a second transverse dimension larger than the first transverse dimension;
operatively coupling at least a portion of the tail member of the first occluding device within a lumen extending through a second occluding device; and
slidably delivering the second occluding device distally along the extending tail member to a uterine ostium of the patient proximate the first occluding device after delivering the first occluding device from the delivery catheter tool within the fallopian tube.
2. The method of claim 1 , wherein slidably delivering the second occluding device is performed with a delivery tool having a curved needle portion.
3. The method of claim 1 , further including removing at least a portion of the tail member extending from the lumen of the second occluding device.
4. The method of claim 3 , further including plugging an end portion of the lumen of the second occluding device.
5. The method of claim 1 , wherein the tail member comprises a polymer.
6. The method of claim 1 , wherein the first occlusion device self-expands when deploying from the delivery catheter tool within the fallopian tube.
7. The method of claim 1 , wherein the first occlusion device comprises fibers to support tissue ingrowth.
8. The method of claim 1 , wherein the first occluding device includes a mesh portion.
