Patterned implant and 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 to control and promote elongation, expansion or contraction along single or multiple axes. As such, controlled and designated stress, tension and compression distribution is promoted across specific or localized areas of the implant.
1. A unitary patterned implant device for treating a pelvic disorder in a patient, comprising:
a non-woven, non-mesh unitary support portion including a plurality of undulating strut members joined to define a plurality of repeating cells having voids, the support portion having first and second opposing anchor portions, the first anchor portion including a first anchor rod, a first barrel, and a first tissue anchor, the first anchor rod being disposed between the first barrel and the first tissue anchor, the first tissue anchor configured to engage with an insertion tool;
a first transition zone having first and second boundary edges and integrally formed with and between the support portion and the first barrel, defining a plurality of transition cells of a different size and shape than the repeating cells of the support portion, and spanning between the support portion and the first barrel such that one or more of the plurality of transition cells extend longitudinally transverse to one or more of the plurality of repeating cells, with one or more arcuate struts extending from the first boundary edge to the second boundary edge of the first transition zone, and the first transition zone tapering from the support portion toward the first barrel; and
a second transition zone spanning between the support portion and the second anchor portion, the second transition zone defining a plurality of transition cells of a different size and shape than the repeating cells of the support portion.
2. The implant device of claim 1 , further including a third transition zone, a fourth transition zone, a first eyelet, and a second eyelet, the third transition zone spanning between the support portion and the first eyelet, the fourth transition zone spanning between the support portion and the second eyelet.
3. The implant device of claim 2 , further including a grommet having a plurality of extending teeth, the grommet integrally formed with at least one of the first eyelet and the second eyelet.
4. The implant device of claim 2 , wherein each of the third transition zone and the fourth transition zone defines a plurality of transition cells of a different size and shape than the repeating cells of the support portion.
5. The implant device of claim 1 , wherein the repeating cells of the support portion are substantially identical in shape.
6. The implant device of claim 1 , further including a plurality of nubs extending from the plurality of undulating strut members and into the voids of the support portion.
7. The implant device of claim 1 , wherein a plurality of the repeating cells display a Negative Poisson ratio during a load application.
8. The implant device of claim 1 , wherein the second anchor portion includes a second anchor rod, a second barrel, and a second tissue anchor, the second transition zone being integrally formed with and between the support portion and the second barrel.
9. The implant device of claim 1 , wherein the first tissue anchor is rotatably coupled to an end portion of the first anchor rod.
10. The implant device of claim 1 , wherein the first anchor rod is generally cylindrical.
11. A unitary implant system for a pelvic disorder in a patient, comprising:
a non-woven, non-mesh unitary support portion including a plurality of undulating strut members joined to define a plurality of repeating cells having voids, the support portion having first and second opposing anchor portions, the first anchor portion including a first anchor rod, a first barrel, and a first tissue anchor, the first anchor rod being disposed between the first barrel and the first tissue anchor, the first tissue anchor coupled to an end portion of the first anchor rod, the first tissue anchor defining one or more tines, the second anchor portion including a second anchor rod, a second barrel, and a second tissue anchor, the second anchor rod being disposed between the second barrel and the second tissue anchor, the second tissue anchor coupled to an end portion of the second anchor rod; and
a first transition zone integrally formed with and between the support portion and the first barrel, and having opposing boundary edges, defining a plurality of transition cells of a different size than the repeating cells of the support portion, and spanning between the support portion and the first barrel such that the plurality of transition cells extend in a direction transverse to an adjacent plurality of the plurality of repeating cells to define one or more arcuate struts extending between the opposing boundary edges of the first transition zone, and the first transition zone narrowing and tapering from the support portion to the first barrel;
a second transition zone spanning between the support portion and the second barrel, the second transition zone defining a plurality of transition cells of a different size and shape than the repeating cells of the support portion; and
an insertion tool having a handle, a needle and a distal tip, the distal tip of the insertion tool configured to engage with the first tissue anchor and the second tissue anchor.
12. The system of claim 11 , further including a third transition zone, a fourth transition zone, a first eyelet, and a second eyelet, the third transition zone spanning between the support portion and the first eyelet, the fourth transition zone spanning between the support portion and the second eyelet.
13. The system of claim 12 , further including a grommet provided with at least one of the first eyelet and the second eyelet.
14. The system of claim 12 , further including an anchor fixation arm engageable with at least one of the first eyelet and the second eyelet.
15. The system of claim 12 , wherein each of the third transition zone and the fourth transition zone defines a plurality of transition cells of a different size and shape than the repeating cells of the support portion.
16. The system of claim 11 , wherein the repeating cells of the support portion are substantially identical in shape.
17. The system of claim 11 , further including a plurality of nubs extending from the plurality of undulating strut members and into the voids of the support portion.
