Claims (26)

1. An implantable prosthesis comprising:

a three-dimensional, tissue infiltratable body of biocompatible material having a proximal end and a distal end spaced from the proximal end, the body including:

a core extending along a core axis from the proximal end to the distal end;

a plurality of body segments arranged circumferentially about the core, each of the plurality of body segments extending in an outward radial direction away from the core axis, each body segment including at least two body panels fabricated from a sheet of the biocompatible material, the sheet being folded about a first fold oriented in the outward radial direction to form the body panels; and

a plurality of chambers formed by the plurality of body segments, the plurality of chambers arranged to face in the outward radial direction away from the core.

2. The implantable prosthesis according to claim 1 , wherein each of the plurality of chambers extends along a corresponding chamber axis which is transverse to the core axis.

3. The implantable prosthesis according to claim 2 , wherein each chamber axis extends in a different radial direction relative to each other.

4. The implantable prosthesis according to claim 3 , wherein the chamber axis of each of the plurality of chambers is oriented at an angle relative to the proximal end, the angle of the chamber axis being the same for each chamber in a first group of chambers.

5. The implantable prosthesis according to claim 2 , wherein each of the plurality of chambers is open in the corresponding outward radial direction.

6. The implantable prosthesis according to claim 1 , wherein each of the plurality of chambers has a size which increases in the outward radial direction.

7. The implantable prosthesis according to claim 6 , wherein each of the plurality of chambers has a width which increases in the outward radial direction.

8. The implantable prosthesis according to claim 1 , wherein the body has a frusto-conical shape.

9. The implantable prosthesis according to claim 1 , wherein the body has a spherical shape.

10. The implantable prosthesis according to claim 1 , wherein the body has a tubular shape.

11. The implantable prosthesis according to claim 1 , wherein the body has a planar configuration at the proximal end and/or the distal end.

12. The implantable prosthesis according to claim 1 , further comprising a first layer of biocompatible material located at the proximal end of the body and a second layer of biocompatible material located at the distal end of the body, the first and second layers being oriented in a direction transverse to the core axis.

13. The implantable prosthesis according to claim 12 , wherein the first and second layers are formed of absorbable material.

14. The implantable prosthesis according to claim 12 , wherein the first and second layers are formed of mesh fabric.

15. The implantable prosthesis according to claim 14 , wherein the mesh fabric is tissue infiltratable.

16. The implantable prosthesis according to claim 1 , wherein the body is formed of absorbable material.

17. The implantable prosthesis according to claim 1 , wherein the body is formed of mesh fabric.

18. The implantable prosthesis according to claim 17 , wherein the mesh fabric is tissue infiltratable.

19. The implantable prosthesis according to claim 17 , wherein each of the body segments includes a sheet of mesh fabric.

20. The implantable prosthesis according to claim 19 , wherein the plurality of body segments are connected together to form the plurality of chambers.

21. The implantable prosthesis according to claim 1 , wherein the plurality of chambers are tissue infiltratable.

22. The implantable prosthesis according to claim 1 , wherein the body is configured to augment and/or reconstruct an anatomical shape of a human breast.
