Abstract
A porous fusion device configured to aid in fusion of two or more biological tissues. The porous fusion device comprising an exterior frame, an exterior lattice cage within the exterior frame, an interior porous lattice structure, and a material injection port disposed at the exterior frame and projecting into the interior porous lattice structure. The interior porous lattice structure may be characterized by a variable density progression that mimics biological tissues and allows for material dispersal therethrough.
Claims20
A porous fusion device, comprising:
- an exterior frame;
- an exterior lattice cage disposed within the exterior frame;
- an interior porous lattice structure disposed within the exterior lattice cage,
- wherein the interior porous lattice structure comprises a gradual decrease in density from the exterior lattice cage to a central-most point of the porous fusion device;
- and
- a material injection port disposed at the exterior lattice cage and projecting into the interior porous lattice structure.
A porous fusion device for fusing two or more tissues, comprising:
- an exterior frame;
- an exterior lattice cage disposed within the exterior frame;
- an interior porous lattice structure disposed within the exterior lattice cage;
- a material injection port disposed at the exterior lattice cage and projecting into the interior porous lattice structure;
- and
- a plurality of material propagation channels disposed within the interior porous lattice structure and extending to the exterior lattice cage,
- wherein the interior porous lattice structure is organized by a variable density from the exterior lattice cage to a central-most point of the porous fusion device,
- wherein the variable density comprises a gradual decrease in density from the exterior lattice cage to the central-most point of the porous fusion device,
- wherein the porous fusion device is configured to be backfilled with a material following insertion into a patient.
A method of instructing use of a porous fusion device, comprising:
- providing the porous fusion device comprising:
- an exterior frame;
