INTERVERTEBRAL DEVICES

Abstract: the present invention relates to an intervertebral fusion device comprising a superior component , an inferior component and a core component . the superior component and the inferior component are receivable in an intervertebral space between first and second vertebrae with the core component insertable between the superior and inferior components to determine a separation between the superior and inferior components. a bone graft conveying aperture is defined in at least one of a superior component top surface of the superior component and an inferior component bottom surface of the inferior component. the core component defines a bone graft material holding space which is enclosed except at at least one of a core component top surface and core component bottom surface of the core component and a bone graft material delivery opening. the bone graft material delivery opening extends from outside the core component side to the bone graft material holding space. the bone graft material delivery opening is closed by a closure component.
