numérique générale 10.general digital 10.
Ce dispositif 10 comporte essentiellement une bande 12 munie de deux extrémités libres mutuellement opposées pourvues de moyens de fermeture complémentaires adaptés pour configurer la bande 12 en forme d'anneau en vue de son positionnement autour de la partie inférieure de l'_sophage ou de la partie supérieure de l'estomac d'un patient pour limiter la quantité de nourriture ingérée par ce dernier, This device 10 essentially comprises a strip 12 provided with two mutually opposite free ends provided with complementary closing means adapted to configure the strip 12 in the form of a ring with a view to its positioning around the lower part of the esophagus or of the part upper stomach of a patient to limit the amount of food ingested by the patient,
comme cela est classique.like this is classic.
Comme on le voit sur cette figure 1, ces moyens de fermeture comportent, d'une part, une partie male 14 constituce par une tête tronconique et une partie femelle 16 complémentaire réalisée sous la forme d2un fourreau généralement cylindrique dans lequel s'insert' la tête As can be seen in this FIG. 1, these closing means comprise, on the one hand, a male part 14 constituted by a frustoconical head and a complementary female part 16 produced in the form of a generally cylindrical sheath in which the head
tronconique 14.tapered 14.
La bande 12 est constituée par un ballonnet gonflable The strip 12 is constituted by an inflatable balloon
pour régler le diamètre interne de l'anneau. to adjust the inner diameter of the ring.
Ainsi, la tête tronconique 14 est raccordée à un conduit 18 débouchant, par l'une de ses extrémités, dans une chambre de gonflage 20 ou de remplissage destinée à être positionnée de manière sous-cutanée et, par son Thus, the frusto-conical head 14 is connected to a conduit 18 opening, at one of its ends, into an inflation or filling chamber 20 intended to be positioned subcutaneously and, by its
extrémité opposée, dans la bande gonflable 12. opposite end, in the inflatable strip 12.
La chambre de gonflage 20 est destinée à permettre le The inflation chamber 20 is intended to allow the
remplissage de la bande en vue de son gonflage. filling the strip for inflation.
Comme mentionné précédemment, en position active, la tête tronconique 14 est insérée dans la partie femelle 16 As mentioned previously, in the active position, the frustoconical head 14 is inserted into the female part 16
et la chambre 20 est implantée en position sous-cutance. and the chamber 20 is implanted in the subcutaneous position.
Par ailleurs, et conformément à l' invention, les moyens de fermeture, à savoir les parties mâle et femelle sont constitués par des moyens de fermeture amovibles, c'est-à-dire que la partie mâle 14 peut être extraite de la partie femelle 16 sans nécessiter de déconnecter la chambre 20. A cet effet, et en référence à la figure 3, la partie femelle 16 est pourvue d'une fente longitudinale 22 autorisant un passage de la partie mâle 14 lorsque l'on Furthermore, and in accordance with the invention, the closing means, namely the male and female parts, are constituted by removable closing means, that is to say that the male part 14 can be extracted from the female part. 16 without the need to disconnect the chamber 20. For this purpose, and with reference to FIG. 3, the female part 16 is provided with a longitudinal slot 22 allowing passage of the male part 14 when one
souhaite ouvrir le dispositif 10.wishes to open the device 10.
Par ailleurs, dans le but de maintenir la partie mâle 14 dans la partie femelle 16, cette dernière est pourvue, de part et d'autre de la fente 22, d'éléments de paroi, respectivement 24 et 26, pourvus chacun d'un orifice, tel que 28, destiné à coopérer avec un organe de maintien de la partie mâle dans la partie femelle. Par exemple, cet organe de maintien est constitué par un rivet 30, c'est-à-dire un organe comprenant une tige 32 dont les deux zones d'extrémité mutuellement opposses 34 et 36 sont chacun pourvus d'une tête s'appuyant sur les faces latérales Furthermore, in order to maintain the male part 14 in the female part 16, the latter is provided, on either side of the slot 22, with wall elements, respectively 24 and 26, each provided with a orifice, such as 28, intended to cooperate with a member for holding the male part in the female part. For example, this holding member is constituted by a rivet 30, that is to say a member comprising a rod 32, the two mutually opposite end regions 34 and 36 are each provided with a head resting on the side faces
mutuellement opposées des éléments de paroi 24 et 26. mutually opposite wall elements 24 and 26.
L'une des têtes est munie d'une face externe profilée permettant son insertion à travers les orifices 28 des One of the heads is provided with a profiled external face allowing its insertion through the orifices 28 of the
éléments de paroi 24 et 26.wall elements 24 and 26.
La tige de l'organe de maintien 30 a une longueur choisie pour que les têtes d'extrémité exercent un effort sur les éléments de paroi 24 et 26 tel que la partie femelle exerce un effort de friction sur la partie mâle suffisant pour empêcher toute ouverture du dispositif après The rod of the holding member 30 has a length chosen so that the end heads exert a force on the wall elements 24 and 26 such that the female part exerts a friction force on the male part sufficient to prevent any opening. of the device after
son implantation autour de l'estomac ou de l'_sophage. its implantation around the stomach or esophagus.
La tige 32 est constituée d'un matériau sécable, c'est-à-dire pouvant être coupé au moyen d'un outil The rod 32 is made of a breakable material, that is to say that can be cut by means of a tool
approprié de manière à permettre l'ouverture du dispositif. suitable to allow the opening of the device.
Afin d'éviter toute perte des éléments de l'organe de maintien après coupure de la tige 32, les têtes d'extrémité In order to avoid any loss of the elements of the holding member after cutting of the rod 32, the end heads
sont réunies au moyen d'un fil de liaison 38. are joined by means of a connecting wire 38.
Dans le but de faciliter l'ouverture du dispositif après avoir coupé la tige 32 de l'organe de maintien, la partie femelle 16 est pourvue d'une languette de préhension pouvant être saisie au moyen d'un outil approprié de manière à ouvrir la fente 22 et permettre le passage de la In order to facilitate the opening of the device after cutting the rod 32 of the holding member, the female part 16 is provided with a gripping tab which can be grasped by means of an appropriate tool so as to open the slot 22 and allow the passage of the
partie mâle 14.male part 14.
Comme on le concoit, le dispositif de traitement qui vient d'être décrit est d'une mise en place relativement aisée. Il est particulièrement adapté à une implantation As can be seen, the processing device which has just been described is relatively easy to set up. It is particularly suitable for implantation
selon une technique de laparoscopie. according to a laparoscopic technique.
Selon cette technique, le dispositif est inséré, à l'état ouvert, dans l'aLdomen d'un patient au moyen d'un trocard approprié. Lors de cette phase d' introduction, la chambre implantable est déconnectée du ballonnet According to this technique, the device is inserted, in the open state, into the aLdomen of a patient by means of an appropriate trocar. During this introduction phase, the implantable chamber is disconnected from the balloon

La bande est alors positionnée autour de l'estomac, en passant par un tunnel disséqué préalablement au niveau de la partie postérieure de l'estomac, de manière à permettre le passage de l'anneau et à obtenir un bon maintien du dispositif dans cette zone, puis le dispositif est maintenu en place par insertion de la partie mâle dans la partie The band is then positioned around the stomach, passing through a tunnel dissected beforehand at the level of the posterior part of the stomach, so as to allow the passage of the ring and to obtain a good maintenance of the device in this area. then the device is held in place by inserting the male part into the part

Les parties mâle et femel le sont alors so l idari s ées au moyen du rivet, en insérant la tête tronconique de ce dernier à travers les orifices ménagés dans les éléments de The male and female parts are then identified by means of the rivet, by inserting the frustoconical head of the latter through the orifices made in the elements of
paroi de la partie femelle.wall of the female part.
Le conduit est alors raccordé à la chambre de gonflage, laquelle est ensuite implantée en position sous cutance. Il convient alors de gonfler le ballonnet du dispositif jusqu'à obtenir une section de passage de The conduit is then connected to the inflation chamber, which is then implanted in the subcutance position. It is then advisable to inflate the balloon of the device until a passage section for
nourriture dans l'estomac ou l'_sophage souhaitée. food in the stomach or esophagus desired.
Comme cela est classique, après implantation, le dispositif a tendance à migrer vers la partie inférieure de l'estomac. Par ailleurs, la partie supérieure de l'estomac, c'est-à-dire située en amont du dispositif a tendance à augmenter de taille rendant dès lors le traitement moins efficace. Ainsi, il est souvent nécessaire de repositionner le As is conventional, after implantation, the device tends to migrate to the lower part of the stomach. Furthermore, the upper part of the stomach, that is to say located upstream of the device tends to increase in size, making the treatment less effective. Thus, it is often necessary to reposition the
dispositif autour de l'estomac ou de l'_sophage. device around the stomach or esophagus.
Pour ce faire, il convient tout d'abord d'ouvrir le dispositif en coupant la tige sécable 32 de l'organe de maintien, en exerçant une traction sur la languette 40 de manière à écarter la fente 22 puis en faisant passer la To do this, it is first of all necessary to open the device by cutting the breakable rod 32 of the holding member, by exerting traction on the tongue 40 so as to spread the slot 22 and then passing the
partie mâle à travers cette dernière. male part through the latter.
Après réouverture, on repositionne alors aisément le dispositif, selon la même technique que celle décrite précédemment pour son insertion autour de l'estomac ou de l'_sophage. En référence aux figures 4 et 5, selon une autre caractéristique de l' invention, pour procéder à ce repositionnement, on utilise un organe de préhension, désigné par la référence numérique générale 42. Cet organe est essentiellement constitué d'une tête de préhension After reopening, the device is then easily repositioned, using the same technique as that described above for its insertion around the stomach or the esophagus. With reference to FIGS. 4 and 5, according to another characteristic of the invention, to carry out this repositioning, a gripping member is used, designated by the general reference numeral 42. This member consists essentially of a gripping head
proprement dite 44 pourvue d'un cathéter de man_uvre 46. proper 44 provided with a maneuvering catheter 46.
La tête de préhension 44 est dotée d'une surface externe arrondie, lisse et dépourvue de tout angle aigu et, intérieurement, d'un logement 48 de forme complémentaire de celle de la partie femelle 16 de manière à venir la recouvrir. Comme on le conçoit, cet organe de préhension 42 permet, d'une part, d'exercer une traction sur le dispositif de manière à le repositionner de manière adéquate et, d'autre part, de permettre un passage de la partie femelle à travers le tunnel ménagé au voisinage de la partie postérieure de l'estomac, en évitant ainsi que les parties saillantes de cette dernière ne constituent des butées empêchant tout déplacement du dispositif ou que ces The gripping head 44 is provided with a rounded external surface, smooth and devoid of any acute angle and, internally, a housing 48 of shape complementary to that of the female part 16 so as to come to cover it. As will be appreciated, this gripping member 42 allows, on the one hand, to exert traction on the device so as to reposition it adequately and, on the other hand, to allow passage of the female part through the tunnel in the vicinity of the posterior part of the stomach, thus avoiding that the projecting parts of the latter do not constitute stops preventing any movement of the device or that these
parties saillantes ne détériorent les tissus avoisinants. protruding parts do not damage surrounding tissue.
On notera que l' invention n'est pas limitée au mode de réalisation décrit précédemment. En effet, au lieu et place du rivet tout autre moyen approprié pour exercer un effort sur la paroi de la partie femelle suffisant pour retenir par friction la partie mâle dans cette dernière pourrait It will be noted that the invention is not limited to the embodiment described above. Indeed, instead of the rivet any other suitable means to exert a force on the wall of the female part sufficient to retain by friction the male part in the latter could
être utilisé.to be used.
On notera également que, de préférence, l' ensemble du dispositif est réalisé en silicone. Avantageusement, on prévoit dans la paroi externe de la bande gonflable, c'est à dire la zone de la paroi situce à l'opposoe de l'estomac ou de l'_sophage, des moyens de renforcement formés par exemple en utilisant une silicone de nature dlfférente de celle utilisée pour la paroi interne, de manière à privilégier le gonflage de la bande vers l'intérieur de l'anneau. De même, il est également possible de noyer dans la bande un repère radio-opaque approprié, par exemple en ajoutant du sulfate de baryum à la silicone, de manière à It will also be noted that, preferably, the entire device is made of silicone. Advantageously, there are provided in the external wall of the inflatable band, that is to say the zone of the wall situated opposite the stomach or the esophagus, reinforcing means formed for example by using a silicone of dlfférente nature of that used for the internal wall, so as to favor the inflation of the band towards the inside of the ring. Likewise, it is also possible to embed in the strip an appropriate radiopaque marker, for example by adding barium sulphate to the silicone, so as to
permettre un repérage de l'anneau au cours d'un suivi post- allow identification of the ring during post-monitoring
opératoire. Enfin, on réalisera de préférence la bande gonflable au moyen d'une silicone colorce afin de faciliter sa pose procedure. Finally, we will preferably make the inflatable strip using a colored silicone to facilitate its installation
