Patent ID: 8366776

Claim:
An intervertebral implant for insertion into a patient between vertebral bodies comprising: a first body including an inferior surface, a superior surface, and a first exterior perimeter surface extending transverse to and connecting the inferior and superior surfaces, the first body including a rigid tapered shape with a height of the first body measured between the inferior and superior surfaces gradually increasing from one end of the first body to an opposing end of the first body, the inferior and superior surfaces of the first body forming a fixed first angle that is aligned in a first direction, the first body having a first recess formed therein and opening to the first perimeter surface; a second body including an inferior surface, a superior surface, and a second exterior perimeter surface extending transverse to and connecting the inferior and superior surfaces, the second body including a rigid tapered shape with a height of the second body measured between the inferior and superior surfaces gradually increasing from one end of the second body to an opposing end of the second body, the inferior and superior surfaces of the second body forming a fixed second angle that is aligned in a second direction, the second body having a second recess formed therein and opening to the second perimeter surface; a single connector comprising a first end, a second end and a narrow intermediate portion, the connector including enlarged portions disposed at the first end and the second end, the connector extending in the first and second recesses to couple the first and second bodies together, the connector positioned along a central plane that extends through the superior and inferior surfaces of each of the first and second bodies, wherein the engagement of the enlarged portions with the recesses prevents the first and second bodies from separating; and each of the first and second bodies include a pair of inwardly facing retainers that are spaced apart a distance that is less then a width of the narrow intermediate portion such that the narrow intermediate portion is secured within the retainers to prevent the connector from dislodging from the first and second bodies, wherein the first and second bodies are stackable into a stacked configuration such that the first and second directions are orthogonal to one another and wherein in the stacked configuration, the interior surface of the first body engages the superior surface of the second body.
