A multi-piece punctal plug has one or more superficial plugs connected to an anchor plug deeper in the naso-lacrimal canaliculus. The anchor is fixed to the wall of the lacrimal duct while the superficial plugs are axially and detachably secured to the anchor plug so that the multi-plug complex may be inserted or removed together as one, or the superficial plugs may be detached separately and replaced securely without disturbing the anchor. Removal and insertion is accomplished by a specific tool having an end for engaging the plugs.

La présente invention concerne un bouchon lacrymal multi-composants comprenant un ou plusieurs bouchons superficiels raccordés à un bouchon dancrage plus profond dans le canalicule naso-lacrymal. Lancrage est fixé à la paroi du canal lacrymal tandis que les bouchons superficiels sont fixés de façon axiale et amovible au bouchon dancrage de sorte que le complexe multi-bouchons puisse être inséré ou enlevé conjointement dune pièce, ou que les bouchons superficiels puissent être détachés séparément et remplacés en toute sécurité sans perturber lancrage. Le retrait et linsertion sont effectués à laide dun outil spécifique ayant une extrémité pour mettre en prise les bouchons.
