Abstract

Dispositif comprenant une pluralité de canaux s'étendant dans le dispositif. Chaque canal est conçu pour contenir un greffon. Le dispositif comprend également une pluralité d'ouvertures. Chaque ouverture de la pluralité d'ouvertures correspond à un canal de la pluralité de canaux. Chaque ouverture de la pluralité d'ouvertures est conçue pour recevoir une aiguille. Le dispositif comprend en outre une pluralité d'évents. Chaque évent de la pluralité d'évents correspond à un canal de la pluralité de canaux. Une aspiration à partir d'une lumière interne de l'aiguille amène le greffon dans le canal correspondant de la pluralité de canaux à être transféré dans la lumière interne de l'aiguille.
