Pelvic implant and treatment method
View Patent ↗A unitary or homogeneous patterned implant is provided. The implant is constructed of patterned cells formed by way of a molding, die casting, laser etching, laser cutting, extruding, and the like. Portions of the implant can be formed into sinusoid or other waveform strut members. One or more undulating anchor arms or rods extend out from the implant for tissue fixation, with the one or more undulating anchor arms including one or more arcuate bends.

an undulating rod member operatively extending out from the support portion, the undulating rod member including a first curved section and a second curved section, the second curved section curving in a direction opposite to the first curved section, the second curved section having a radius larger than a radius of the first curved section; and
a tissue anchor coupled to a distal end of the undulating rod member, the tissue anchor having one or more tines configured to engage soft tissue of the patient.
2. The implant device of claim 1 , further including at least one anchoring arm having a distal tissue anchor and an extending rod member adapted to slidably engage and secure with one of the first and second eyelets of the support portion, wherein the distal tissue anchor of the at least one anchoring arm is adapted for fixation to the sacrospinous ligament of the patient.
3. The implant device of claim 1 , further including a grommet having a plurality of extending teeth, the grommet integrally formed with at least one of the first and second eyelets.
4. The implant device of claim 1 , wherein the tissue anchor is rotatably coupled to the distal end of the undulating rod member.
5. The implant device of claim 1 , further including at least one transition zone extending out from the support portion to a proximal end of the undulating rod member.
6. The implant device of claim 1 , wherein the undulating rod member includes a third curved section.
7. The implant device of claim 1 , wherein the second curved section has a length larger than a length of the first curved section.
8. A unitary implant system for treating vaginal prolapse in a patient, comprising:
a non-woven unitary support portion including a plurality of undulating strut members joined at and spanning out from a plurality of fixed junctions to define a plurality of repeating cells having voids, the support portion having first and second opposing anchoring portions operatively extending out from the support portion; and
first and second opposing undulating rod members operatively extending out from the respective first and second opposing anchoring portions, the first undulating rod member including a first curved section, and a second curved section, the second curved section having a length larger than a length of the first curved section,
a first tissue anchor coupled to a distal end of the first undulating rod member; and
a second tissue anchor coupled to a distal end of the second undulating rod member.
9. The system of claim 8 , further including first and second eyelet portions.
10. The system of claim 9 , further including first and second grommets provided with the respective first and second eyelet portions, the first and second grommets having a plurality of extending teeth.
11. The system of claim 10 , wherein the first and second grommets are integrally formed with the first and second eyelets.
12. The system of claim 8 , wherein the first and second undulating rod members are polymer rod members.
13. The system of claim 8 , further including at least one transition zone extending out from the support portion to at least one of the first and second opposing undulating rod members.
14. The system of claim 8 , wherein the first undulating rod member includes a third curved section, the first curved section defining a first C-shape, the second curved section defining a second C-shape, and the third curved section defining a third C-shape.
15. The system of claim 8 , wherein the second curved section has a radius larger than a radius of the first curved section.
16. The system of claim 8 , wherein the non-woven unitary support portion is formed from a polymer molding process.
17. The system of claim 8 , wherein portions of the outer periphery of the unitary support portion includes rounded struts to assist in reducing tissue snagging.
18. An implant device for supporting tissue of a patient, comprising:
a support portion adapted to support pelvic tissue within the patient; and
first and second opposing anchor portions, the first anchor portion including an undulating rod member operatively extending out from the support portion, the undulating rod member including a first curved portion and a second curved section, the second curved section curving in a direction opposite to the first curved section, the second curved section having a length larger than a length of the first curved section, the second curved section having a radius larger than a radius of the first curved section; and
a tissue anchor coupled to a distal end of the undulating rod member, the tissue anchor having one or more tines configured to engage with soft tissue of the patient.
19. The implant device of claim 18 , further including first and second eyelet portions.
20. The implant device of claim 19 , further including first and second grommets provided with the respective first and second eyelet portions, the first and second grommets having a plurality of extending teeth.
21. The implant device of claim 20 , wherein the first and second grommets are integrally formed with the respective first and second eyelets.
22. The implant device of claim 18 , wherein the support portion is constructed as a molded unitary support portion including a plurality of undulating strut members joined at and spanning out from a plurality of fixed junctions to define a plurality of repeating cells having voids.
