Abdominal closure method and device variations
Abdominal closure reinforcement methods and tissue anchoring devices for reducing the rate of abdominal wall closure dehiscence are described. The tissue anchors avoid a permanent footprint of foreign material and precluding materials spanning the interior layer of the abdominal closure where risk to visceral structures exists.
1. A tissue anchor apparatus, comprising:
a first platform defining at least one anchoring member having a length extending from a surface of the first platform, the at least one anchoring member having a terminal piercing end;
a second platform defining at least one elongated channel extending along a surface of the second platform from a peripheral edge of the second platform and terminated at a position of the at least one anchoring member when the at least one anchoring member is extended through the second platform,
wherein an orientation of the second platform relative to the first platform is maintained by one or more shoulders defined along a length of the at least one anchoring member.
2. The apparatus of claim 1 further comprising a retaining platform defining at least one opening which correspond to a position of the at least one anchoring member.
3. The assembly of claim 1 further comprising one or more securing elements attachable to a portion of the second platform for securement to an additional tissue anchor positioned opposite to the tissue anchor.
4. The assembly of claim 3 wherein the one or more securing elements comprise a length of suture or biasing element.
5. The assembly of claim 1 wherein the first platform defines a trapezoidal configuration having four anchoring members.
6. The assembly of claim 1 wherein each anchoring member extends from the surface in parallel with one another.
7. The assembly of claim 1 wherein each anchoring member is angled relative to the first platform.
8. The assembly of claim 1 wherein the one or more shoulders are defined by regions of reduced diameter along the length of the at least one anchoring member.
9. The assembly of claim 1 the second platform further comprises at least one secondary anchoring member extending from a surface of the platform opposite to the surface of the first platform.
10. The assembly of claim 9 wherein the at least one secondary anchoring member comprises tines each having a length which is less than the at least one anchoring member from the first platform.
11. The assembly of claim 1 wherein the first platform and second platform have a parallel orientation relative to one another.
12. The assembly of claim 1 wherein each of the at least one anchoring member have a uniform height relative to the surface of the first platform.
13. The assembly of claim 1 wherein a portion of the at least one anchoring member extending beyond the second platform when engaged to the first platform is removable.
14. The assembly of claim 1 wherein the first platform is configured to be bioabsorbable.
15. The assembly of claim 1 wherein the second platform is configured to be bioabsorbable.
16. The assembly of claim 1 further comprising a third platform configured to secure the second platform to the at least one or more anchoring member.
17. The assembly of claim 1 wherein a position of the at least one elongated channel along the edge is aligned with the at least one anchoring member.
18. A tissue anchor apparatus, comprising:
a first platform defining at least one anchoring member having a length extending from a surface of the first platform, the at least one anchoring member having a terminal piercing end and defining an engagement region along the length;
a second platform defining an opening for correspondingly receiving the at least one anchoring member and defining at least one elongated channel extending along a surface of the second platform from a peripheral edge of the second platform such that the at least one channel is aligned with and terminated at a position of the at least one anchoring member when the at least one anchoring member is extended through the second platform; and
a third platform configured to be positioned upon the second platform when engaged upon the at least one anchoring member such that the second platform is secured to the at least one anchoring member along the engagement region.
19. The apparatus of claim 18 further comprising additional anchoring members extending from the surface of the first platform.
20. The apparatus of claim 18 wherein the second platform further defines an attachment region.
21. The apparatus of claim 20 further comprising a length of suture or a biasing element for coupling to the attachment region.
22. The apparatus of claim 18 wherein the second platform is relatively smaller in diameter than the first platform.
23. The apparatus of claim 18 wherein the second platform is relatively larger in diameter than the first platform.
24. The apparatus of claim 18 wherein the first platform and second platform have a parallel orientation relative to one another.
25. The apparatus of claim 18 wherein a portion of the at least one anchoring member extending beyond the second platform when engaged to the first platform is removable.
26. The apparatus of claim 18 wherein the first platform is configured to be bioabsorbable.
27. The apparatus of claim 18 wherein the second platform is configured to be bioabsorbable.
28. The apparatus of claim 18 wherein the third platform is configured to be bioabsorbable.
29. The apparatus of claim 18 wherein the second platform is secured to the at least one anchoring member along the engagement region such that an orientation of the second platform is maintained relative to the first platform.
