Title (EN) DEVICE FOR USE IN THE EYE
(FR) DISPOSITIF POUR L'OEIL
Abstract:
(EN) A glaucoma filtration implant comprises a generally tubular body section having an oblong external diameter formed of a continuous convex curve. The device preferably has a flow resistance means provided by a portion of the internal lumen having a reduced diameter. For instance a flow resistance means may have a length of up to 5000 $g(m)m and a diameter in the range 15 to 50 $g(m)m, the diameter being selected so as to achieve a pressure drop along the resistance means in the range 5 to 15 mm Hg. Preferably the internal conduit for flow of liquid also includes a removable flow inhibitor, which can be removed after implantation by a laser, for instance an ophthalmic YAG laser. The device is made of biocompatible materials.
(FR) L'invention concerne un implant pour filtration d'un glaucome, comprenant une section corps généralement tubulaire présentant un pourtour oblong formé par une courbe convexe continue. Le dispositif comporte, de préférence, un élément de résistance à l'écoulement assuré par une partie du canal intérieur à diamètre réduit. L'élément de résistance à l'écoulement peut, par exemple, mesurer jusqu'à 5000 $g(m)m en longueur et entre 15 et 50 $g(m)m en diamètre, le diamètre étant choisi de manière à obtenir une chute de pression comprise entre 5 et 15 mm Hg, le long de l'élément de résistance. De préférence, le canal intérieur pour l'écoulement du liquide comprend également un élément amovible inhibiteur d'écoulement, pouvant être retiré après implantation au laser, tel qu'un laser ophtalmique YAG. L'invention est faite de matériaux biocompatibles
