BONE IMPLANT FOR ENCLOSING BONE MATERIAL

Abstract

A bone implant for enclosing bone material is provided. The bone implant comprises a mesh having an inner surface and an outer surface opposing the inner surface. The inner surface is configured to receive a bone material when the inner surface of the mesh is in an open configuration. A plurality of projections are disposed on or in at least a portion of the inner surface of the mesh. The plurality of projections extend from at least the portion of the inner surface of the mesh and are configured to engage a section of the inner surface of the mesh or a section of the outer surface of the mesh or both sections of the inner and outer surfaces of the mesh in a closed configuration so as to enclose the bone material. A tray, a kit and a method of making the bone implant are also provided.

Description

Claims

1-12. (canceled)

13. A kit for filling bone material in a bone implant, the kit comprising: a bone implant comprising a mesh having an inner surface and an outer surface opposing the inner surface, the inner surface configured to receive a bone material when the inner surface of the mesh is in an open configuration;a plurality of projections disposed on or in at least a portion of the inner surface of the mesh, the plurality of projections extending from at least the portion of the inner surface of the mesh and configured to engage a section of the inner surface of the mesh or a section of the outer surface of the mesh or both sections of the inner and outer surfaces of the mesh in a closed configuration so as to enclose the bone material; anda tray having a proximal end, a distal end, and a longitudinal recess disposed therebetween, the longitudinal recess configured to receive the mesh in the open configuration to allow filling of the bone material into the bone implant.

14. A kit of claim 13, wherein the recess of the tray forms a slot for receiving the mesh.

15. A kit of claim 13, wherein the longitudinal recess is a channel, a trough, a slot, a groove or grooves, an indent or indents or a combination thereof.

16. A kit of claim 13, wherein the longitudinal recess in centrally located in the tray.

17. A kit of claim 13, wherein the tray is made of a metal, thermoform, a polymer or a combination thereof.

18. A kit of claim 13, wherein (i) the bone material comprises fully demineralized bone fibers and surface demineralized bone chips; (ii) the bone material comprises calcium phosphate; or (iii) the bone material comprises autograft.

19. A method of implanting a bone implant at a surgical site, the method comprising; providing a bone implant comprising a mesh having an inner surface and an outer surface opposing the inner surface, the inner surface configured to receive a bone material when the inner surface of the mesh is in an open configuration; a plurality of projections disposed on or in at least a portion of the inner surface of the mesh, the plurality of projections extending from at least the portion of the inner surface of the mesh and configured to engage a section of the inner surface of the mesh or a section of the outer surface of the mesh or both sections of the inner and outer surfaces of the mesh in a closed configuration so as to enclose the bone material;disposing the bone material in the inner surface of the mesh by orientating the mesh in the open configuration;enclosing the bone material in the mesh by orientating the mesh in the closed configuration; andplacing the bone implant at the surgical site thereby implanting the bone implant at the surgical site.

20. A method according to claim 19, wherein (i) the plurality of projections are hooks; (ii) the inner surface comprises a plurality of recesses configured to mate with the plurality of projections of the inner surface; or (iii) the bone material is fully demineralized bone fibers and surface demineralized bone chips.

21. A kit of claim 13, wherein (i) the mesh is foldable in the closed configuration to enclose the bone material; (ii) the inner surface of the mesh comprises a fold line extending from a distal end to a proximal end of the inner surface, the fold line forming a compartment to receive the bone material; (iii) the mesh is configured to roll the section of the inner surface over the bone material to enclose the bone material; (iv) the plurality of projections are disposed on or in the entire inner surface of the mesh or (v) the section of the inner surface comprises a plurality of recesses configured to mate with the plurality of projections of the inner surface.

22. A kit of claim 13, wherein the bone material is partially enclosed by the mesh.

23. A kit of claim 13, wherein the inner surface of the mesh comprises a distal end and a proximal end and a compartment extending from the distal end to the proximal end, the compartment configured to receive the bone material, the compartment having none of the plurality of the projections.
