Abrégé
(EN)
Intervertebral fusion device comprising a superior component, an inferior component, and a core component. The superior component comprises first and second superior parts which are coupled to each other to allow the first and second superior parts to move apart to thereby increase a perimeter of the superior component top side. The inferior component comprises first and second inferior parts which are coupled to each other to allow the first and second inferior parts to move apart to thereby increase a perimeter of the inferior component bottom side. The core component is configured for insertion between the superior and inferior components whereby separation between the superior and inferior components is determined. The core component interengages with each of the superior and inferior components upon insertion. The superior and inferior components are unattached to each other before the core component is inserted between the superior and inferior components. As the core component is progressively inserted between the superior and inferior components, the core component: bears against the first and second superior parts to push the first and second superior parts progressively apart; and bears against the first and second inferior parts to push the first and second inferior parts progressively apart.

L'invention concerne un dispositif de fusion intervertébrale comprenant un composant supérieur, un composant inférieur et un composant central. Le composant supérieur comprend des première et seconde parties supérieures qui sont couplées l'une à l'autre pour permettre aux première et seconde parties supérieures de se déplacer l'une par rapport à l'autre pour augmenter ainsi un périmètre du côté supérieur de composant supérieur. Le composant inférieur comprend des première et seconde parties inférieures qui sont couplées l'une à l'autre pour permettre aux première et seconde parties inférieures de se déplacer l'une par rapport à l'autre pour augmenter ainsi un périmètre du côté inférieur de composant inférieur. Le composant central est conçu pour être inséré entre les composants supérieur et inférieur, ce qui permet de déterminer la séparation entre les composants supérieur et inférieur. Le composant central entre en prise avec chacun des composants supérieur et inférieur lors de l'insertion. Les composants supérieur et inférieur ne sont pas fixés l'un à l'autre avant que le composant central ne soit inséré entre les composants supérieur et inférieur. Lorsque le composant central est progressivement inséré entre les composants supérieur et inférieur, le composant central : est en appui contre les première et seconde parties supérieures pour pousser les première et seconde parties supérieures progressivement ; et est en appui contre les première et seconde parties inférieures pour pousser progressivement les première et seconde parties inférieures.
