Implantable slings and anchor systems
View Patent ↗Various embodiments of a mesh or implant systems are provided. The implants can include one or more anchors, arms and the like. The anchors can include hingeable or patterned finger extension to facilitate tissue penetration and retention. Various tensioning and adjustment mechanisms, devices and methods are further provided for the implant systems.
1. An implant system for treating pelvic disorders, comprising:
an elongate implant having a support portion, at least one extension portion and at least one generally arrow-shaped anchor device having a profile dimension and disposed at an end portion of the at least one extension portion, the at least one anchor device having a tapered tip portion and one or more extending barbs and adapted to extend through target tissue; and
a spacer element including one or more extending barbs extending out generally radially from opposing sides of a longitudinal axis of the spacer element, the spacer element adapted to slidably engage the at least one extension portion such that the spacer element is slidable along the at least one extension portion and through the target tissue for positioning between the at least one anchor device and the target tissue to provide tensioning adjustment for the elongate implant, wherein the spacer element is generally arrow-shaped and has a profile dimension substantially the same as the profile dimension of the at least one anchor device.
2. The system of claim 1 , wherein the at least one extension portion includes two extension portions.
3. The system of claim 2 , wherein the at least one anchor device includes two extending barbs.
4. The system of claim 1 , wherein the at least one anchor device includes two extending barbs.
5. The system of claim 1 , further including a second spacer element.
6. The system of claim 1 , wherein at least the support portion of the implant is constructed of a mesh material.
7. The system of claim 1 , wherein the implant is constructed of a mesh material.
8. The system of claim 1 , wherein the target tissue is the obturator internus muscle.
9. The system of claim 1 , wherein the spacer element is a two-piece construct having a first portion and a second portion.
10. The system of claim 9 , wherein the first portion and the second portion snap together around the at least one extension portion.
11. An implant system for treating pelvic disorders, comprising:
an implant having a support portion, first and second extension portions, a first generally arrow-shaped anchor having a profile size dimension and provided at an end portion of the first extension portion, and a second generally arrow-shaped anchor provided at an end portion of the second extension portion, the first and second anchors including a tapered distal portion and one or more extending barbs and adapted to extend through target tissue; and
a spacer element having a longitudinal axis with first and second sides, and a spacer profile size dimension substantially the same as the profile size dimension of the first generally arrow-shaped anchor, and having a tapered distal portion and one or more extending barbs extending out generally transversely from the first and second sides of the longitudinal axis, and adapted to surround a portion of at least the first extension portion such that the spacer element is slidable along the first extension portion and through the target tissue for positioning between the first anchor and the target tissue to provide tensioning adjustment for the implant.
12. The system of claim 11 , wherein the first and second anchors include two extending barbs.
13. The system of claim 11 , further including a second spacer element.
14. The system of claim 11 , wherein at least the support portion of the implant is constructed of a mesh material.
15. The system of claim 11 , wherein the implant is constructed of a mesh material.
16. The system of claim 11 , wherein the target tissue is the obturator internus muscle.
17. The system of claim 11 , wherein the spacer element is a two-piece construct having a first portion and a second portion.
18. The system of claim 17 , wherein the first portion and the second portion snap together around the first extension portion.
