Abstract[English]
Embodiments disclosed herein relate to an infusion cannula for infusion/venting of fluids to/from the eye to control intraocular pressure. The infusion cannula includes a tubular body with a tubular inlet located at a proximal end of the tubular body and a tubular outlet located at a distal end of the tubular body. The tubular outlet is aligned with a first longitudinal axis and configured to extend through a septum of a valved cannula hub. The infusion cannula includes a retention piece extending from or coupled to the tubular body. The retention piece has an annular body surrounding the tubular body at the distal end of the tubular body and configured to be coupled to the valved cannula hub. An inner surface of the annular body has a profile configured to form a snap fit with an overhang formed along an outer surface of the valved cannula hub.[French]
Des modes de réalisation de la présente invention concernent une canule de perfusion pour l'infusion/l'évacuation de fluides vers/depuis l'oeil pour réguler la pression intraoculaire. La canule de perfusion comprend un corps tubulaire avec une entrée tubulaire située au niveau d'une extrémité proximale du corps tubulaire et une sortie tubulaire située au niveau d'une extrémité distale du corps tubulaire. La sortie tubulaire est alignée avec un premier axe longitudinal et conçue pour s'étendre à travers un septum d'un embout de canule à valve. La canule de perfusion comprend une pièce de retenue s'étendant à partir du corps tubulaire ou couplée au corps tubulaire. La pièce de retenue a un corps annulaire entourant le corps tubulaire au niveau de l'extrémité distale du corps tubulaire et conçu pour être couplé à l'embout de canule à valve. Une surface interne du corps annulaire a un profil configuré pour former un ajustement par pression avec un surplomb formé le long d'une surface externe de l'embout de canule à valve.
