Custom Density 3D-Printed Spinal Implants
Summary
USPTO published patent application US20260108359A1 filed on October 24, 2025 (Application No. 19368950) for a spinal implant with custom density manufactured via 3D printing. The implant body defines a longitudinal axis with distal and proximal end portions, opposed side surfaces, and top and bottom surfaces configured to engage vertebral bodies with a surface roughness between 3-4 μm. A cavity extends through the top and bottom surfaces covering at least 25% of the surface area, with first orifices through the top surface and second orifices through the bottom surface connected by a plurality of channels. Four inventors are listed: Thomas Morrison, Richard W. Woods, Richard Pellegrino, and Michael Prosser. Medical device manufacturers developing 3D-printed spinal implants should review this intellectual property filing for potential freedom-to-operate implications or licensing considerations.
“In some embodiments, a spinal implant (10, 110, 210, 310, 400) is provided and includes a body portion defining a longitudinal axis.”

What changed
The patent application describes a spinal implant (10, 110, 210, 310, 400) comprising a body portion with a longitudinal axis, distal and proximal end portions, opposed side surfaces, and top and bottom surfaces configured to engage vertebral bodies with a surface roughness between 3-4 μm. A cavity extends through the top and bottom surfaces with a surface area of at least 25% of the top or bottom surface area. First orifices are defined through the top surface and second orifices through the bottom surface, connected by a plurality of channels.
Medical device manufacturers focused on spinal implant development, particularly those utilizing additive manufacturing techniques, should monitor this intellectual property filing. The specific design parameters around surface roughness, cavity geometry, and orifice-channel architecture may indicate future product development directions and potential licensing or clearance requirements.

Abstract
In some embodiments, a spinal implant (10, 110, 210, 310, 400) is provided and includes a body portion defining a longitudinal axis. The body portion includes a distal end portion, a proximal end portion, opposed side surfaces that extend between the distal and proximal end portions, and top and bottom surfaces configured and adapted to engage vertebral bodies. The top and bottom surfaces have a surface roughness between 3-4 μm. A cavity extends through the top and bottom surfaces defining a surface area that is at least 25% of a surface area of the top surface or the bottom surface. First orifices (24, 124, 224, 324, 426a) are defined through the top surface and second orifices (34, 134, 234, 334, 426b) are defined through the bottom surface. The second orifices are connected to the first orifices by a plurality of channels.
