Abstract:
A device for dilating and restoring a lacrimal duct of a human eye, through which lacrimal fluid flows from the eye into a nasal cavity, comprising:a first hollow cannula with a distal end having at least one longitudinal gap;a guide passing through the first hollow cannula and having a distal end which dilates the distal end of the first cannula in a region of the at least one longitudinal gap;a hollow body surrounding an outside contour of the first hollow cannula in a distal zone; anda second hollow cannula which is pushed over the first hollow cannula and extends up to an end on a proximal side of the hollow body, which is placed on the first hollow cannula to lock the first hollow cannula and prevent axial sliding thereof on the proximal side.
