Abstract

The implant valve comprises, housed inside a rigid tube 21, a flexible tube 26 opening at one end 32 into the anterior chamber of the eye and at its opposite end 27 into the conjunctiva, the said flexible tube being capable of contracting in transverse cross-section by a remote control.

Description

Valve-implant pour soigner le glaucome;
L'invention a pour objet une valve-implant pour soigner le glaucome.Valve-implant to treat glaucoma;
The subject of the invention is a valve-implant for treating glaucoma.

On a déjà proposé de soigner le glaucome à l'aide d'un dispositif ou valve-implant constitué par un tube souple à deux branches faisant entre elles un angle obtus, l'une des branches étant destinée à être introduite dans la chambre antérieure de l'oeil et étant fermée à son extrémité sous réserve de fentes pouvant s'ouvrir sous l'effet d'une surpression dans la chambre, l'autre branChe débouchant dans la conjonctive.It has already been proposed to treat glaucoma using a device or valve-implant constituted by a flexible tube with two branches forming an obtuse angle between them, one of the branches being intended to be introduced into the anterior chamber of the eye and being closed at its end subject to slots which can open under the effect of an overpressure in the chamber, the other branch opening into the conjunctiva.

Une telle valve-implant présente un certain nombre d'inconvénients, bien connus des spécialistes, et qui proviennent de l'obturation accidentelle, partielle ou totale, des fentes et des difficultés d'évacuation du liquide.Such a valve-implant has a certain number of drawbacks, well known to specialists, and which arise from accidental obtention, partial or total, of the slits and of the difficulties of evacuation of the liquid.

La valve-implant selon l'invention est caractérisée par ce fait que, comprenant un tube souple, celui-ci est ouvert à ses deux extrémités, y compris celle placée dans la chambre intérieure de l'oeil, ledit tube souple étant logé dans un tube rigide, à deux branches faisant entre elles un angle obtus, par rapport auquel l'extrémité du tube souple dans la chambre antérieure fait saillie, le fonctionnement de la valve-implant étant provoqué par la contraction du tube souple dans une partie où il est entouré par le tube rigide.The implant valve according to the invention is characterized in that, comprising a flexible tube, the latter is open at its two ends, including that placed in the inner chamber of the eye, said flexible tube being housed in a rigid tube, with two branches forming an obtuse angle between them, with respect to which the end of the flexible tube in the anterior chamber protrudes, the operation of the valve-implant being caused by the contraction of the flexible tube in a part where it is surrounded by the rigid tube.

Selon une forme de réalisation, la contraction du tube souple est obtenue par l'action mécanique qu'exercent sur la paroi du tube souple des mini-aimants soumis à l'action d'un champ magnétique extérieur. Avantageusement, les mini-aimants sont noyés dans l'épaisseur de la paroi du tube souple.According to one embodiment, the contraction of the flexible tube is obtained by the mechanical action exerted on the wall of the flexible tube of the mini-magnets subjected to the action of an external magnetic field. Advantageously, the mini-magnets are embedded in the thickness of the wall of the flexible tube.

Avec une telle valve-implant, les incidents attachés à l'utilisation de la valve-implant connue sont évités.With such a valve-implant, incidents associated with the use of the known valve-implant are avoided.

Dans la description qui suit, faite à titre d'exemple, on se réfère aux dessins annexés#, dans lesquels la figure 1 est une vue schématique en élévation; la figure 2 est une vue schématique en coupe longitudinale; la figure 3 est une vue en coupe suivant la ligne III-III de la figure 2; la figure 4 est une vue en coupe à plus grande échelle d'une partie de la paroi du tube souple; la figure 5 est une vue analogue à la figure 4, mais pour une autre condition; la figure 6 est une vue très schématique d'un globe oculaire avec la valve-implant; la figure 7 est une vue analogue à la figure 2,mais pour une autre condition.In the description which follows, given by way of example, reference is made to the appended drawings #, in which FIG. 1 is a schematic view in elevation; Figure 2 is a schematic view in longitudinal section; Figure 3 is a sectional view along line III-III of Figure 2; Figure 4 is an enlarged sectional view of a portion of the wall of the flexible tube; Figure 5 is a view similar to Figure 4, but for another condition; Figure 6 is a very schematic view of an eyeball with the valve-implant; Figure 7 is a view similar to Figure 2, but for another condition.

La valve-implant selon l'invention comprend un tube extérieur rigide 21, par exemple en polyméthylmétacrylate, présentant une branche 22 et une branche 23, substantiellement rectilignes, se prolongeant l'une l'autre, dont les lignes moyennes font entre elles un angle o#tus voisin de 1ode. C rigide 21 présente des pattes 24 et 25 pour assurer sa fixation dans l'oeil, en principe sans points de suture.The implant valve according to the invention comprises a rigid outer tube 21, for example made of polymethylmethacrylate, having a branch 22 and a branch 23, substantially rectilinear, extending from one another, the mean lines of which form an angle between them o # close to 1ode. C rigid 21 has tabs 24 and 25 to secure it in the eye, in principle without stitches.

A l'intérieur du tube rigide 21 est logé un tube souple 26, par exemple en silicone,dont l'extrémité 27,opposée à celle destinée à être placée dans la chambre antérieure de l'oeil, est assemblée par un repli 29 à l'extrémité en regard 28 du tube rigide 21. A son extrémité opposée, le tube 26 se prolonge, au-delà d'une cloison annulaire 31 fermant le tube rigide 21, suivant une extrémité 32, ouverte, dont la longueur peut d'ailleurs être réglée, par sectionnement, au cours de l'opération chirurgicale pour la mise en place de l'implant. La traversée par le tube 26 de la cloison annulaire 31 terminant le tube rigide 21 est étanche.Inside the rigid tube 21 is housed a flexible tube 26, for example made of silicone, the end 27 of which, opposite to that intended to be placed in the anterior chamber of the eye, is assembled by a fold 29 to the opposite end 28 of the rigid tube 21. At its opposite end, the tube 26 is extended, beyond an annular partition 31 closing the rigid tube 21, along an open end 32, the length of which may moreover be adjusted, by sectioning, during the surgical operation for the placement of the implant. The passage through the tube 26 of the annular partition 31 terminating the rigid tube 21 is sealed.

Dans l'épaisseur de la paroi 33 constitutive du tube 26, sont présents des grains 36, en matière magnétique, enrobés dans une pellicule souple 37, par exemple en polytétrafluoréthylène (téflon). Des encoches 45 sur la paroi 33 facilitent la déformation de celle-ci à la flexion.In the thickness of the wall 33 constituting the tube 26, grains 36 are present, made of magnetic material, coated in a flexible film 37, for example made of polytetrafluoroethylene (teflon). Notches 45 on the wall 33 facilitate the deformation thereof when bending.

Au repos, la condition est celle montrée sur la figure 2. At rest, the condition is that shown in Figure 2.

La partie 34 du tube 26 logeant les grains 36 est en contact ou quasi en contact avec la partie en regard 38 du tube rigide 21. Le tube souple 26 ménage une libre communication à section transversale constante entre la chambre antérieure 9
(figure 6) du globe oculaire et la conjonctive 46.The part 34 of the tube 26 housing the grains 36 is in contact or almost in contact with the opposite part 38 of the rigid tube 21. The flexible tube 26 provides free communication at constant cross section between the anterior chamber 9
(figure 6) of the eyeball and the conjunctiva 46.

En approchant un puissant aimant de la valve-implant et en le déplaçant dans un mouvement convenable, les grains 36, 37 sollicitent à la déformation la partie 34 de la paroi du tube souple 26 logeant les grains pour la rapprocher de la partie en regard 39 de ladite paroi souple. La partie 39 peut prendre appui surlapartie adjacente du tube rigide. Le liquide (humeur aaueuse) contenu dans l'intervalle 41 entre lesdites parties est sollicité à l'expulsion et, en cas W xzès, s'coule vers l'extérieur par l'orifice 42 du tube 26.By bringing a strong magnet to the valve-implant and moving it in a suitable movement, the grains 36, 37 stress the part 34 of the wall of the flexible tube 26 housing the grains to bring it closer to the opposite part 39 of said flexible wall. Part 39 can rest on the adjacent part of the rigid tube. The liquid (austere humor) contained in the interval 41 between said parts is urged upon expulsion and, in the case W xzes, flows outward through the orifice 42 of the tube 26.

En éloignant l'aimant, le tube souple 26 reprend sa conformation initiale en raison de l'élasticité de la paroi qui le constitue. By moving the magnet away, the flexible tube 26 resumes its initial conformation due to the elasticity of the wall which constitutes it.

L'action est renouvelée si et quand il est besoin.The action is repeated if and when it is needed.

La valve-implant selon l'invention permet ainsi de maintenir à la valeur convenable la pression régnant à l'intérieur de la chambre antérieure de l'oeil dans des conditions optimales d'efficacité et de sécurité.The valve-implant according to the invention thus makes it possible to maintain the pressure prevailing inside the anterior chamber of the eye at the appropriate value under optimal conditions of efficiency and safety.

Son introduction dans l'oeil peut être réalisée facilement.Its introduction into the eye can be carried out easily.

Elle y est bien supportée. It is well supported there.
