Appl. No.:

13/334146

Inventors:

Chad J. Patterson - Port Washington WI, US
Jennifer M. Schneider - Germantown WI, US

Assignee:

Titan Spine LLC - Mequon WI

International Classification:

A61F 2/44

US Classification:

623 1716, 623 1711

Abstract:

An implant that has a predefined ratio of load bearing surface area to the overall size of the implant body and specifically to the surface area of a centrally located opening of a vertical aperture which connects to a center void area or passage defined by the implant body shape. This invention discloses a critical ratio or balance between loading of contained graft material through the hollow center or central passage of the implant and the implant's frictional load bearing or contact area with e. g. , adjacent vertebral bones. Application of this invention to a spinal implant provides an improved integration and integration rate of the graft material or the fusion of the adjacent vertebral bone structures. The ratio between implant load bearing surface area and implant central opening area maximizes implant internal volume and allows a large passage disposed medial laterally to allow for radiographic verification of fusion growth.

International Classification:

A61F 2/44

US Classification:

623 1716, 623 1711, 606 90, 606100

Abstract:

An interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, a substantially hollow center, a single vertical aperture, and a roughened surface topography on at least the top surface. The posterior portion has a generally rounded nose profile, and has a shorter height than the anterior portion such that the spinal implant comprises a lordotic angle for aligning the spine of a patient. The junctions of the top and bottom surfaces and the anterior portion comprise a sharp edge to resist expulsion of the spinal implant upon implantation.

US Classification:

623 1716, 264162, 264400, 216 53

Abstract:

An interbody spinal implant, such as a solid-body or composite implant, includes at least one graft contact surface as one or more of the internal surfaces of the implant. The graft contact surface, for example, having at least one ridge or groove is designed to contact and promote retention and stabilization of bone growth-inducing materials placed within the internal openings of the implant body. In addition, the ridges or grooves may influence the biological processes to promote bone healing and fusion. Also disclosed are processes of fabricating the graft contact surfaces and other surface topographies on the implant.

US Classification:

623 1716, 29592

Abstract:

An interbody spinal implant having at least three distinct surfaces including (1) at least one integration surface having a roughened surface topography including macro features, micro features, and nano features, without sharp teeth that risk damage to bone structures; (2) at least one graft contact surface having a coarse surface topography including micro features and nano features; and (3) at least one soft tissue surface having a substantially smooth surface including nano features. Also disclosed are processes of fabricating the different surface topographies, which may include separate macro processing, micro processing, and nano processing steps.

US Classification:

623 1716, 264162, 216 53

Abstract:

A composite interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions; a first integration plate affixed to the top surface of the body; and an optional second integration plate affixed to the bottom surface of the body. At least a portion of the first integration plate, optional second integration plate, or both has a roughened surface topography including macro features, micro features, and nano features, without sharp teeth that risk damage to bone structures, adapted to grip bone through friction, inhibit migration of the implant, and promote bone growth. Also disclosed are processes of fabricating a roughened surface topography, which may include separate and sequential macro processing, micro processing, and nano processing steps.

US Classification:

623 1716, 427 224

Abstract:

An implantable device for treating disc degenerative disease and arthritis of the spine. The implant is sized for placement into an intravertebral disc space. The implant has a body with a predetermined, defined, repeating, three-dimensional pattern at least partially on at least one of its surfaces. The pattern is adapted to create a surface area of bone-contacting features that enhance in-growth and biological attachment to a biocompatible material. Also disclosed are process steps for making the implant.
