Methods and devices for deployment into a lumen
View Patent ↗The invention described is directed to an intracorporeal occluding device having elements with non-traumatic ends and devices, systems and methods for occluding the lumens of anatomical passageways and/or for delivering drugs or other substances to the bodies of human or animal subjects.
1. An occluding device for a patient's body lumen, comprising:
a first expansive element secured to a central location and including a non-traumatic end radially spaced from the central location when in an expanded configuration; and
a second expansive element secured to the central location and including a non-traumatic end radially spaced from the central location when in the expanded configuration;
wherein each non-traumatic end is a separate, discrete mesh pad with fibers attached thereto, and each separate, discrete mesh pad is bonded onto a respective expansive element and configured to face an adjacent wall of the body lumen when in the expanded configuration in the body lumen.
2. The occluding device of claim 1 , further comprising an extension member secured to the central location.
3. The occluding device of claim 2 , wherein the extension members comprises a coil.
4. The occluding device of claim 1 , further comprising a membrane inter-disposed between the first and second expansive elements.
5. The occluding device of claim 4 , wherein the membrane is dissolvable in vivo.
6. The occluding device of claim 4 , wherein the membrane comprises polytetrafluoroethylene (PTFE).
7. The occluding device of claim 4 , wherein the membrane contains a contraceptive or drug.
8. The occluding device of claim 1 , further comprising fibers dispersed between the first and second expansive elements.
9. The occluding device of claim 8 , wherein the fibers dispersed between the first and second expansive elements comprise a polyester or a polyamide.
10. The occluding device of claim 8 , wherein the fibers dispersed between the first and second expansive elements comprise polyethylene terephthalate (PET) or expanded polytetrafluoroethylene (ePTFE).
11. The occluding device of claim 1 , further comprising a hydrogel element.
12. The occluding device of claim 11 , wherein the hydrogel element is porous to allow tissue ingrowth.
13. The occluding device of claim 11 , wherein the hydrogel element is secured to an extension member that is secured to the central location.
14. The occluding device of claim 11 , wherein the hydrogel element is secured to the central location.
15. The occluding device of claim 1 , wherein the fibers attached to each separate, discrete mesh pad comprise polyethylene terephthalate (PET).
16. The occluding device of claim 1 , wherein at least one of the first and second expansive elements is straight.
17. The occluding device of claim 1 , wherein at least one of the first and second expansive elements is curved.
18. The occluding device of claim 1 , wherein the first and second expansive elements are self-expansive.
19. The occluding device of claim 1 , wherein the fibers are attached to pores in each separate, discrete mesh pad.
20. The occluding device of claim 1 , wherein the fibers are attached to each separate, discrete mesh pad with a glue.
