Spinal implant system and method
A delivery system comprising an agent and a foldable covering including a first surface disposed with the agent and a second surface connectable with the first surface to intra-operatively dispose the covering in a selected configuration.
1. A spinal implant comprising:
an agent; and
a foldable covering including a first surface substantially covered by loops and disposed with the agent, and a second surface substantially covered by hooks and connectable with the first surface to intra-operatively dispose the covering in a selected configuration, wherein the covering comprises at least two panels, the at least two panels comprising a first panel having an outer face formed from the second surface, a second panel, and a third panel having an inner face formed from the first surface, the at least two panels configured to form a folded configuration such that the agent is contained completely within the at least two panels, and the outer face of the first panel and the inner face of the third panel engage by the loops and the hooks in the folded configuration.
2. A spinal implant as recited in claim 1 , wherein the covering comprises a porous mesh.
3. A spinal implant as recited in claim 1 , wherein the selected configuration of the covering includes a cross sectional shape selected from generally circular or generally oval.
4. A spinal implant as recited in claim 1 , wherein the selected configuration of the covering includes a shape selected from tubular, rectangular, cube or mesh bag.
5. A spinal implant as recited in claim 1 , wherein the agent comprises autograft or allograft.
6. A spinal implant as recited in claim 1 , wherein the agent comprises demineralized bone matrix comprising particles and fibers of demineralized bone.
7. A spinal implant as recited in claim 1 , wherein the agent comprises demineralized bone matrix fibers and demineralized bone matrix particles in a 30:70 ratio.
8. A spinal implant as recited in claim 1 , wherein the agent comprises protein, bone morphogenetic proteins, carbohydrate, lipids, collagen, allograft bone, autograft bone, tricalcium phosphate, hydroxyapatite, growth and differentiation factors, carriers for growth factors, growth factors extracts of tissue, bone marrow aspirate, concentrates of lipid derived or marrow derived adult stem cells, umbilical cord derived stem cells, committed or partially committed cells from osteogenic or chondrogenic lineage, antimicrobials, antibiotics, statins, or combinations thereof.
9. A spinal implant as recited in claim 1 , wherein the covering comprises a material selected from bioerodible polymers, bioabsorbable polymers, biodegradable biopolymers, synthetic polymers, copolymers or combinations thereof.
10. A spinal implant as recited in claim 1 , wherein the first panel connects to the second panel by a first fold line and the third panel connects to the second panel by a second fold line.
11. A spinal implant comprising:
an agent including autograft; and
a foldable polymer mesh sheet including a first surface substantially covered by loops and disposed with the agent, and a second surface substantially covered by hooks and connectable with the first surface to intra-operatively dispose the sheet in a selected implant configuration, wherein the sheet comprises at least two panels, the at least two panels comprising a first panel having an outer face formed from the second surface, a second panel, and a third panel having an inner face formed from the first surface, the at least two panels configured to form a folded configuration such that the agent is contained completely within the at least two panels, and the outer face of the first panel and the inner face of the third panel engage by the loops and the hooks in the folded configuration.
12. A spinal implant as recited in claim 11 , wherein the sheet is foldable to the selected implant configuration.
