1. An intervertebral implant comprising: a body portion defining a central longitudinal axis, the body portion including a distal end portion, a proximal end portion, anterior and posterior walls that extend between the distal and proximal end portions, and top and bottom surfaces configured and adapted to engage vertebral bodies, the anterior and posterior walls extending between the top and bottom surfaces of the body portion, each of the distal and proximal end portions including an arcuate portion, each of the anterior and posterior walls including a transition portion disposed between the arcuate portions of the respective distal and proximal end portions, wherein at least one of the top and bottom surfaces includes a plurality of substantially concentrically arranged ridges that define an elliptical pattern, and each of the anterior and posterior walls includes a first, planar sloped portion extending between the arcuate portion of the proximal end portion and the transition portion and a second, planar sloped portion extending between the transition portion and the arcuate portion of the distal end portion, wherein the first and second planar sloped portions define an acute angle with respect to the central longitudinal axis of the body portion, and wherein a first of the plurality of concentrically arranged ridges defines an uninterrupted ridge towards a center of the intervertebral implant and a second of the plurality of concentrically arranged ridges defines an interrupted ridge away from the center of the intervertebral implant.
