The present invention relates to an intervertebral fusion device () comprising a superior component (), an inferior component () 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. The superior, inferior components and core components comprise respective formations and profiles. The formations () present a barrier to separation of the core from one of the inferior and superior components during insertion of the core component. The profiles guide the core component during insertion of the core component while presenting no barrier to separation from each other during its insertion. The components comprise further formations () which present a barrier to separation of the components from each other once the core has been fully inserted between the inferior and superior components.

Inter vertebral devices

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.
