Abstract
Official abstract text for this publication.
An interbody spacer is provided including 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 interbody spacer includes first orifices defined through the top surface. The first orifices include orifices having first and second cross-sectional configurations and the first orifices are arranged in rows extending along the longitudinal axis.
First claim
Opening claim text (preview).
What is claimed is: 1. An interbody spacer comprising: a body portion defining a longitudinal axis, the body portion including 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; and first orifices defined through the top surface; second orifices defined through the bottom surface, wherein a respective orifice of the first and second orifices is in open communication thereby defining a channel therebetween, wherein the channel defines a plurality of cross-sections, a center cross-section of the plurality of cross-sections defining a cross-sectional area that is greater than cross-sections disposed adjacent the top surface and the bottom surface. 2. The interbody spacer of claim 1 , wherein the channel defines a plurality of cylinders, a center cylinder having a cross-sectional area greater than a cross-sectional area of adjacent cylinders. 3. The interbody spacer of claim 1 , wherein the channel defines a plurality of spheres, a center sphere having a cross-sectional area different than a cross-sectional area of adjacent spheres. 4. The interbody spacer of claim 1 , wherein a center portion of the channel defines a cylindrical profile and upper and lower portions of the channel define a frusto-conical profile. 5. The interbody spacer of claim 4 , wherein a diameter of each frusto-conical profile decreases in a direction towards the center of the channel such that the diameter of each frusto-conical profile at a center portion of the channel is less than a diameter of the cylindrical profile. 6. The interbody spacer of claim 1 , wherein a center portion of the channel defines a cylindrical profile and the upper and lower portions of the channel define an hourglass profile. 7. The interbody spacer of claim 1 , wherein a center portion of the channel defines a spherical profile and the upper and lower portions of the channel define an hourglass profile. 8. The interbody spacer of claim 1 , wherein the body portion is formed from powder processed using Selective Laser Powder Processing.
