The present invention relates to an implantable cage for holding tissue graft material. The cage includes a chamber configured and dimensioned to receive the tissue graft material and at least one side wall defining the chamber. In one embodiment, the cage is made of a biodegradable material. In another embodiment, the cage is made of a material that includes a bone-growth enhancer.
1. An implantable cage holding an implantable material, the cage comprising:
a chamber configured and dimensioned to receive the implantable material; and
at least one side wall defining the chamber,
wherein an implantable material is disposed in the chamber and the implantable material expands when contacted with liquid and wherein the cage is made of allograft and the at least one side wall is a mesh.
2. The cage of claim 1 wherein the cage is made of allograft.
3. The cage of claim 1 wherein the at least one side wall has a generally cylindrical shape.
4. The cage of claim 1 wherein the at least one side wall includes a series of openings for tissue ingrowth.
5. The cage of claim 4 wherein the at least one side wall is a mesh.
6. An implantable cage for holding an implantable material, comprising:
a chamber configures and dimensioned to receive the implantable material; and
at least one side wall defining the chamber and including a plurality of first filaments generally parallel to each other and a plurality of second filaments generally parallell to each other and interesting the plurality of first filaments to form a plurality openings in the at least one side wall,
wherein an implantable material is disposed in the chamber and the implantable material expands when contacted with liquid.
7. The cage of claim 6 wherein the cage is compressible.
8. The cage of claim 7 wherein the at least one side wall is a mesh.
9. The cage of claim 7 wherein the cage is made of a polymeric material.
10. The cage of claim 9 wherein the at least one side wall is a mesh.
11. An implantable cage for holding an implantable material, the cage comprising:
a chamber configured and dimensioned to receive the implantable material; and
at least one side wall defining the chamber and including a plurality of first filaments generally parallel to each other and a plurality of second filaments generally parallel to each other and intrsecting the plurality of first filaments to form a plurality openings in the at least one side wall,
wherein the at least one side wall has a generally cylindrical shape,
wherein the cage is made of a biodegradable material and the biodegradable material includes a bone-growth enhancer.
12. An implantable cage for holding an implantable material, the cage comprising:
a chamber configured and dimensioned to receive the implantable material; and
at least one side wall defining the chamber and including a plurality of first filaments generally parallel to each other and a plurality of second filaments generally parallel to each other and intersecting the plurality of first filaments to form a plurality openings in the at least one side wall,
wherein the cage is made of biodegradable material and the biodegradable material includes a bone-growth enhancer.
