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. a first spider segment having a first expansive element having a first end secured to a central location in the occluding member and a non-traumatic end radially spaced from the first end when in an expanded configuration and, at least one additional expansive element having a first end secured to the central location in the occluding member and a non-traumatic end radially spaced from the central location in the expanded configuration; and
b. a second spider segment axially spaced from the first spider segment, having a first expansive element having a first end secured to the central location in the occluding member and a non-traumatic end radially spaced from the first end when in an expanded configuration and at least one additional expansive element having a first end secured to the central location in the occluding member and a non-traumatic end radially spaced from the central location 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 wherein a connecting member interconnects the first spider segment with an adjacent spider segment.
3. The occluding device of claim 2 wherein the connecting member is straight.
4. The occluding device of claim 3 wherein at least one connecting member extends between each spider segment and an adjacent spider segment.
5. The device of claim 3 wherein the first, second and intermediate spider segments are axially aligned.
6. The device of claim 3 wherein the spider segments are connected to adjacent spider segments by a connecting member which extends axially along the central location within the occluding member.
7. The device of claim 1 additionally comprising at least one extension member having a first extension member end and a free end, the first extension member end secured to the central location.
8. The device of claim 7 wherein the extension member comprises a coil.
9. The device of claim 7 wherein the free end is non-traumatic.
10. The occluding device of claim 1 further comprising at least one hydrogel element, which upon insertion into the patient expands to block the lumen.
11. The occluding device of claim 10 wherein the hydrogel element is porous to allow tissue ingrowth.
12. The occluding device of claim 10 wherein the hydrogel element carries a contraceptive drug.
13. The occluding device of claim 10 wherein the hydrogel element is between the first and second spider segments.
14. The occluding device of claim 2 wherein the adjacent spider segment is the second spider segment.
15. The occluding device of claim 2 wherein the connecting member is curved.
16. The occluding device of claim 1 including at least one intermediate spider segment which is axially disposed between the first and second spider segments and which has: a first expansive element having a first end secured to the central location in the occluding member and a non-traumatic end radially spaced from the first end when in an expanded configuration and at least one additional expansive element having a first end secured to the central location in the occluding member and a non-traumatic end radially spaced from the first end when in the expanded configuration.
17. The device of claim 1 additionally comprising fibers inter-disposed between the first and second spider segments.
18. The device of claim 1 additionally comprising a therapeutic substance on at least one expansive element.
19. The device of claim 1 additionally comprising a membrane inter-disposed between at least one of the spider segments.
20. The occluding device of claim 1 wherein each of the mesh pads comprise a molded part bonded onto the respective expansive element.
21. An occluding device for a patient's body lumen, comprising:
a. a first spider segment having a first expansive element having a first end secured to a central location in the occluding member and a non-traumatic end radially spaced from the central location when in an expanded configuration and, at least one additional expansive element having a first end secured to the central location in the occluding member and a non-traumatic end radially spaced from the central location in the expanded configuration; and
b. a second spider segment axially spaced from the first spider segment, having a first expansive element having a first end secured to the central location in the occluding member and a non-traumatic end radially spaced from the central location when in an expanded configuration and at least one additional expansive element having a first end secured to the central location in the occluding member and a non-traumatic end radially spaced from the central location 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.
22. The occluding device of claim 21 wherein each of the mesh pads comprise a molded part bonded onto the respective expansive element.
23. The occluding device of claim 21 wherein a connecting member interconnects the first spider segment with the second spider segment.
24. The occluding device of claim 21 further comprising a membrane inter-disposed between at least one of the first and second spider segments.
