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.
Claims18
An implantable device, comprising
- a body having a top surface and a bottom surface, the top surface, the bottom surface, or both the top and bottom surfaces having a surface topography comprising first, second, and third surface patterns without sharp protrusions;
- the first surface pattern including a plurality of dimples having a first depth dimension, the second surface pattern including a plurality of dimples having a second depth dimension, and the third surface pattern including a plurality of dimples having a third depth dimension, the first depth dimension being greater than the second depth dimension, and the second depth dimension being greater than the third depth dimension, wherein a portion of the second surface pattern overlaps the first surface pattern and a portion of the second surface pattern does not overlap the first surface pattern, and a portion of the third surface pattern overlaps the second surface pattern and a portion of the third surface pattern does not overlap the second surface pattern, and wherein the third surface pattern supports in-growth of bone into the body and positively modulates osteoblast maturation and regulates bone morphogenic protein signaling.
