Mesh for enclosing bone material and methods of use

A kit for filling bone material in a bone implant, the kit comprising:

• a bone implant for enclosing bone material, the bone implant comprising a mesh having one or more pores, 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 outer surface of the mesh or both the inner surface and outer surface of the mesh, each of the plurality of projections having a first end and a second end opposite the first end, the first end contacting the inner surface of the mesh, the outer surface of the mesh or both the inner surface and outer surface of the mesh, the first end having a first surface area larger than a second surface area of the second end and larger than a surface area of the one or more pores of the mesh, the second end extending from at least the portion of the inner surface, the outer surface of the mesh or both the inner surface and outer 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;
• and
• a 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.

A method of implanting a bone implant at a surgical site, the method comprising:

• providing a bone implant for enclosing bone material, the bone implant comprising a mesh having one or more pores, 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 outer surface of the mesh or both the inner surface and outer surface of the mesh, each of the plurality of projections having a first end and a second end opposite the first end, the first end contacting the inner surface of the mesh, the outer surface of the mesh or both the inner surface and outer surface of the mesh, the first end having a first surface area larger than a second surface area of the second end and larger than a surface area of the one or more pores of the mesh, the second end extending from at least the portion of the inner surface, the outer surface of the mesh or both the inner surface and outer 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;
• and
• placing the bone implant at the surgical site thereby implanting the bone implant at the surgical site.
