Implant frames for use with settable materials and related methods of use
View Patent ↗Intervertebral implant system for intervertebral implantation, are disclosed. An intervertebral implant system according to the present disclosure includes a frame having a peripheral wall defining a space therein, and a settable material introducible into the space of the frame. The settable material is a biocompatible load bearing material including and not limited to bone, composites, polymers of bone growth material, collagen, and insoluble collagen derivatives. The settable material is injectable into the space defined by the frame. The settable material may have an initial fluid condition wherein the fluid settable material cures to a hardened condition.
1. An intervertebral implant system for intervertebral implantation, comprising:
A first ribbon-like or band-like frame having a first peripheral wall defining a first space therein, a second ribbon-like or band-like frame having a second peripheral wall defining a second space therein; and
first and a second settable materials that are introduced into the first and second spaces, respectively of the first and second ribbon-like or band like frames,
wherein the first ribbon-like or band-like frame includes a pair of free ends joinable to one another, or at least one opening in the first peripheral wall, and the second ribbon-like or band-like frame includes a pair of free ends joinable to one another, or at least one opening in the second peripheral wall, and the first and second materials include at least one of bone, composites, polymers of bone growth material, collagen, and insoluble collagen derivatives; and wherein the first and second settable materials each have an initial fluid condition and are cured to a hardened condition in the first and second spaces respectively, wherein the settable material in the first space is harder and has a different porosity than the settable material in the second space.
2. The intervertebral implant system of claim 1 , wherein each frame is constructed from at least one of titanium, titanium alloy, steel, shape memory alloy, resorbable polymer, non-resorbable polymer, ceramic, and organic materials.
3. The intervertebral implant system of claim 2 , wherein the first and second settable materials are biocompatible load bearing materials.
4. The intervertebral implant system of claim 3 , wherein the first and second settable materials are injectable into the first and second spaces defined by each frame.
5. The intervertebral implant system of claim 1 , wherein at least one of an upper edge and a lower edge of each frame is shaped.
6. The intervertebral implant system of claim 1 , wherein at least one of the upper edge of each frame and the lower edge of each frame includes at least one of a plurality of projections formed along a length of each frame, and a continuous projection extending along a length of each frame.
7. The intervertebral implant system of claim 1 , wherein each frame is flexible along at least a portion of a length thereof.
8. The intervertebral implant system of claim 1 , further comprising a cap positionable within the space defined by each frame, the cap being dimensioned to extend beyond at least each free end of each frame.
9. The intervertebral implant system of claim 1 , wherein each frame is linearly expandable.
10. The intervertebral implant system of claim 1 , further comprising at least one plug configured and dimensioned for insertion into each opening of each frame, wherein the at least one plug prevents the escape of the first and second settable materials from the first and second spaces.
11. The intervertebral implant system of claim 1 , wherein the peripheral wall of each frame is at least partially collapsible.
12. The intervertebral implant system of claim 1 , wherein each frame is substantially wedge-shaped.
13. The intervertebral implant system of claim 1 , wherein the first or second peripheral wall includes at least one of a planar inner surface and a planar outer surface.
14. The intervertebral implant system of claim 1 , wherein the first or second peripheral wall includes at least one of a convex inner surface and a planar outer surface.
15. The intervertebral implant system of claim 1 , wherein the first or second peripheral wall includes at least one of a concave inner surface and a planar outer surface.
16. The intervertebral implant system of claim 1 , wherein the first or second peripheral wall includes at least one of a saw-toothed inner and outer surface.
17. The intervertebral implant system of claim 1 , wherein a length of the perimetral wall defining the first and second space of each frame is adjustable.
18. The intervertebral implant system of claim 1 , wherein the first or second peripheral wall has an I-shaped transverse cross-sectional profile.
19. The intervertebral implant system of claim 1 , wherein the first or second peripheral wall is fabricated from strands of resorbable polymers.
20. The intervertebral implant system of claim 1 , further comprising:
a support plate securable to adjacent intervertebral discs; and
a fixation means extendable through the support plate and into the first or second peripheral wall of the frame.
21. The intervertebral implant system of claim 1 , wherein the first frame and the second frame are concentric with each other.
