Abstract

A spinal implant device has a synthetic or metallic or a combination thereof of these materials in an implant body structure and stem cells in a coating, or a sheet, wrap or a membrane wrap applied to surfaces on the implant body structure or alternatively filled with a plug of stem cell laden material. The implant body structure preferably has an aperture or channel The spinal implant device may include anchoring holes to secure the device to the spinal skeletal structure with fasteners or alternatively can simply be held in place by and between adjacent vertebrae.

First claim

What is claimed is:

1 . A spinal implant device comprising:
a synthetic or metallic implant body structure for insertion on or into the skeletal spinal structure; stem cells dispersed onto the implant body structure in a spray coated mist, the spray mist being applied to the exterior outer surfaces on the synthetic or metallic implant body structure and dried to form a stem cell laden outer thin membrane, skin-like wrap onto exterior outer surfaces and conforming to the exterior outer surfaces on the synthetic or metallic implant body structure.

2 . The spinal implant of claim 1 further comprises:
an aperture or channel incorporated in the implant body structure.

3 . The spinal implant of claim 1 wherein the body structure is made of a synthetic implantable grade plastic.

4 . The spinal implant of claim 3 wherein the synthetic plastic is an implantable grade thermoplastic material.

5 . The spinal implant of claim 4 wherein the thermoplastic material is one of PEEK (polyether ether ketone), polyethylene, ultra high molecular weight polyethylene, acetal copolymer, polyphenylsulfone, polysulfone, polythermide, implantable grade lennite UHME-PE.

6 . The spinal implant of claim 5 wherein the implantable grade thermoplastic is polyether ether ketone.

7 . The spinal implant of claim 1 wherein the implant body structure is made of titanium.

8 . The spinal implant of claim 1 wherein the implant body structure is made of stainless steel.

9 . The spinal implant of claim 1 wherein the implantable device is unanchored to the spinal structure and held in place by and between adjacent vertebrae.

10 . The spinal implant of claim 1 wherein the spinal implantable device is spray mist coated with the stem cell laden membrane at the surgical site.

11 . The spinal implant of claim 1 wherein the spinal implantable device is spray mist coated with a stem cell laden membrane coated with the stem cells at a manufacturing site by having the implant body structure being sterilized, then spray mist coated in a sterile environment and sealed in a sterile packaging for later shipment and use.

12 . The spinal implant of claim 1 wherein the stem cell membrane is re-hydrated at the time of use.

13 . A prepackaged sterile spinal implant comprising:
a package or container sterile filled with a spinal implant having a synthetic or metallic body structure coated or wrapped with a coating or membrane or sheet laden with stem cells.

14 . The prepackaged sterile implant of claim 13 wherein the prepackaged spinal implant coated or wrapped in a material laden with stem cells is sealed in a package or container with a sterile liquid medium.

15 . A spinal implant device comprises:
a synthetic or metallic implant body structure for insertion on or into the skeletal spinal structure; stem cells in a spray coated mist, the spray mist being applied to exterior outer surfaces on the synthetic or metallic implant body structure.

16 . The spinal implant of claim 15 further comprises:
an aperture or channel incorporated in the implant body structure.

17 . The spinal implant of claim 15 wherein the body structure is made of a synthetic implantable grade plastic.

18 . The spinal implant of claim 17 wherein the synthetic plastic is an implantable grade thermoplastic material.

19 . The spinal implant of claim 18 herein the thermoplastic material is one of PEEK (polyether ether ketone), polyethylene, ultra high molecular weight polyethylene, acetal copolymer, polyphenylsulfone, polysulfone, polythermide, implantable grade lennite UHME-PE.

20 . The spinal implant of claim 19 wherein the implantable grade thermoplastic is polyether ether ketone.
