Patterned sling implant and method
View Patent ↗Embodiments of elongate pelvic implants and methods for treating pelvic conditions, such as incontinence, are provided. The implants can include a tissue support portion, one or more extension portions and one or more anchors. The implant is constructed as a unitary sling implant. The implant can be constructed or formed in a generally elongate shape to provide a lattice support structure of repeated cells.
1. A unitary patterned implant for treating incontinence in a patient, comprising:
a non-woven unitary elongate sling having:
a support portion including a plurality of strut members joined at and spanning out from a plurality of fixed junctions, the support portion defined along a first plane;
first and second extension portions;
at least one tissue anchor having one or more deformable tines adapted for fixation to soft tissue of the patient; and
a transition strength zone including a plurality of elongate arcuate members, an end of each arcuate member integrally formed with the at least one tissue anchor, the transition strength zone extending from and generally along the same plane as one of the first and second extension portions, and between the at least one tissue anchor and one of the first and second extension portions, to facilitate stress or tension distribution between the at least one tissue anchor and one of the first and second extension portions, wherein the at least one tissue anchor is integrally formed with the transition strength zone and one of the first and second extension portions.
2. The implant of claim 1 , wherein the at least one tissue anchor extends out generally transverse from the first plane of the support portion and the one or more deformable tines extend out generally transverse from the at least one tissue anchor along a second plane generally parallel with the first plane of the support portion.
3. The implant of claim 1 , wherein the at least one anchor extends out generally in plane with the first plane of the support portion.
4. The implant of claim 3 , wherein the at least one anchor is substantially equal in thickness to at least one of the first and second extension portions.
5. The implant of claim 1 , wherein the at least one anchor includes two opposing end anchors.
6. The implant of claim 1 , wherein the plurality of strut members are sinusoidal shaped to define a plurality of pinwheel cell configurations.
7. The implant of claim 1 , wherein the at least one anchor includes a body lumen adapted to receive the distal end of a needle tool.
8. The implant of claim 1 , wherein the plurality of strut members includes one or more edge retention features extending to provide tissue engagement.
9. The implant of claim 1 , wherein the support portion is generally wider than the first and second extension portions.
10. A unitary patterned implant system for treating incontinence in a patient, comprising:
a non-woven unitary elongate sling including:
a support portion having a plurality of undulating strut members joined at and spanning out from a plurality of fixed junctions;
first and second extension portions;
first and second end anchors extending from respective of the first and second extension portions, the first and second anchors having extending flexible tines adapted for fixation to soft tissue of the patient;
a transition strength zone including a plurality of elongate arcuate members, an end of each arcuate member integrally formed with the at least one tissue anchor, the transition strength zone extending from and generally along the same plane as the first extension portion, and between the first end anchor and the first extension portion, to facilitate stress or tension distribution, wherein at least the first end anchor is integrally formed with the transition strength zone and the first extension portion; and
an introducer needle tool having a handle portion and a needle, wherein the needle includes a distal tip adapted to selectively engage with the first or second end anchors to facilitate deployment and tissue fixation.
11. The system of claim 10 , wherein the first and second end anchors are substantially equal in thickness to the first and second extension portions.
12. The system of claim 10 , wherein the plurality of undulating strut members are sinusoidal shaped to define a plurality of pinwheel cell configurations.
13. The system of claim 10 , wherein at least one of the first and second end anchors includes a body lumen adapted to receive the distal tip of the introducer needle tool.
14. The system of claim 10 , wherein the plurality of undulating strut members include one or more edge retention features extending to provide tissue engagement.
15. The system of claim 10 , wherein the support portion is generally wider than the first and second extension portions.
16. The system of claim 10 , wherein the support portion is generally narrower than the first and second extension portions.
17. The system of claim 10 , wherein the introducer needle tool includes an actuation mechanism in operable communication with the distal tip to facilitate selective disengagement of the first or second end anchors.
18. The system of claim 10 , wherein the needle of the introducer needle tool is generally curved.
