Abstract

Des modes de réalisation de la présente invention concernent des systèmes et des procédés d'injection rétininienne. Selon certains aspects, un procédé comprend l'insertion d'une partie d'extrémité distale d'un conduit creux d'un injecteur médical dans un oeil d'un patient jusqu'à ce que la partie d'extrémité distale atteigne un emplacement de référence, l'injecteur médical ayant un boîtier à partir duquel le conduit creux s'étend distalement et confirme le placement de la partie d'extrémité distale du conduit creux dans l'emplacement de référence. Après confirmation, le procédé comprend en outre le prolongement distal de la partie d'extrémité distale du conduit creux par rapport au boîtier et depuis l'emplacement de référence de sorte que la partie d'extrémité distale pénètre dans une région d'injection de l'oeil. Lorsque la partie d'extrémité distale du conduit creux est placée dans la région d'injection de l'oeil, le médicament est transporté dans la région d'injection à travers le conduit creux.
