Definitions
- the present invention relates to the technical field of surgical implants intended to be implanted in the body of a patient around biological organ (s) constituting a pocket or a conduit, and more particularly to gastric rings designed to treat obesity by implantation of a flexible gastric ring intended to form a closed loop around the stomach to reduce the diameter of the opening of the stoma.
- the present invention relates to an implantable surgical ring for clamping biological organ (s) constituting a pocket and / or a duct in order to modify the passage section of said organ, said ring being in the form of a flexible strip extending between a first and a second end, said flexible strip being provided towards said first and second ends of respective male and female closure elements arranged to cooperate so that the flexible strip forms a closed loop, the female closure element permanently forming a closed collar.
- ancillary diseases such as cardiovascular diseases, hypertension, diabetes or even severe arthritis in particular.
- This closing system proves, at least in its general principle, generally appreciated by surgeons, since the closing operation is done in the continuity of the strapping of the stomach, and in the same direction of this strapping. The surgeon can thus perform the complete operation of making the closed loop around the stomach using a substantially continuous gesture.
- the head must be made of a relatively rigid material, so as to guarantee a stable closure of the ring.
- such an actuator has a generally rigid character which hardly lends itself to the implementation of a male / female closure system requiring the passage in force by elastic deformation of the male element in the female element.
- it appears completely compromised if we base our on the teaching of document SE-449 430, to produce a male / female closing system when the ring is provided with an actuator of the electric motor type.
- the invention therefore aims to remedy the various drawbacks listed above, and to propose a new surgical ring, in particular gastric, having a closure system of the male / female type particularly safe, and not requiring in particular high effort for its implementation by the surgeon, even when the male element has a large size.
- Another object of the invention is to propose a new surgical ring, in particular a gastric ring, the closure system of which can be activated and deactivated at will.
- Another object of the invention is to propose a new surgical ring, in particular a gastric ring, having a particularly reliable closure system.
- Another object of the invention is to propose a new surgical ring, in particular a gastric ring, having a particularly stable closure system.
- Another object of the invention is to propose a new surgical ring, in particular a gastric ring, the closure system of which is particularly well suited to the presence of an actuator intended to generate a variation in the internal perimeter of the ring.
- an implantable surgical ring for clamping biological organ (s) constituting a pocket and / or a conduit in order to modify the passage section of said member, said ring being in the form of a flexible strip extending between a first and a second end, said flexible strip being provided towards said first and second ends of respective male and female closure elements arranged to cooperate so that the flexible band forms a closed loop, the female closing element permanently forming a closed collar, characterized in that said female element comprises a structural discontinuity at the level of which the deformability of the female element is greater than that from the rest of the female element.
- FIG. 1 shows, in a partial perspective view, an example of a first embodiment of a gastric ring according to the invention, when the latter is in the open position, that is to say that it does not form a closed loop.
- - Figure 2 illustrates, in a perspective view, the gastric ring of Figure 1 in the unlocked closed position, said ring being equipped with a receiving antenna.
- FIG. 4 illustrates, in a partial perspective view, the female closure element of the gastric band shown in FIGS. 1 to 3.
- FIG. 5 illustrates, in a partial perspective view, the cooperation of the female closure element shown in Figure 4 and a male element, being introduced into the female element.
- FIG. 6 illustrates, in a perspective view, an example of a second alternative embodiment of a gastric ring according to the invention, said gastric ring being in the unlocked closed position.
- Figure 8 illustrates, in a perspective view, the female element of Figure 7 when in the passage configuration.
- FIG. 9 illustrates, in a sectional view, a detail of embodiment of the gastric band of FIG. 2.
- Figure 10 illustrates, in a top view, the female closure element of a gastric ring according to a fourth embodiment of the invention, said ring being in the locked closed position.
- the invention may thus relate in particular to rings used to treat urinary or faecal incontinence, or used around blood vessels to regulate blood flow, for example.
- the ring will be implanted around the bladder or urinary tract, and in the case of faecal incontinence, it will be implanted around the gastrointestinal tract, and in particular around the anal structures of the intestine.
- Figures 1 to 10 illustrate a gastric ring 1, 10 according to the invention intended to be implanted around the stomach of a patient by forming a substantially circular loop, in order to achieve gastric restriction by reducing the diameter of the opening of the stoma.
- the gastric band 1, 10 according to the invention is in the form of a flexible band 2, 20, said flexible band preferably being a flexible tubular element, the flexible and elastic envelope of which has a smooth surface for make it atraumatic, so that it is easily supported by the patient and the stomach tissue.
- the flexible band 2, 20 is provided towards its first end 3 with a male closing element 5, 50.
- the flexible band 2, 20 is also provided towards its second end 4, 40, 400 with a female closing element 6 , 60, 600.
- Said male 5, 50 and female 6, 60, 600 closing elements are arranged to cooperate so as to ensure the closing of the flexible band 2, 20 around the stomach to form a closed loop between the two ends 3, 4, 40, 400, as shown in Figures 2 and 6 for example.
- the gastric band 1, 10 then takes place, once closed, substantially in the form of a torus of revolution, of circular section for example, externally delimited by a mono- or multi-layer envelope which can advantageously be formed of a protective coating, for example based on or made of silicone.
- the male closing element 5, 50 comprises at least a first portion 7, 70, as well as a second portion 8, the cross section of the first portion 7, 70 being substantially greater than that of the second portion 8.
- the size of the first portion 7, 70 is substantially greater than that of the second portion 8.
- the male element 5, 50 is intended to be force-fitted through its first portion 7, 70 into the female element 6, 60, 600 until the female element 6, 60, 600 cooperates in closing interlocking with the second portion 8 of the male element 5, 50.
- Said second portion 8 is therefore intended to be interposed between on the one hand the first portion 7, 70, and on the other hand the first end 3 of the flexible strip 2, 20. The first end 3 is thus extended by the second portion 8, which is itself extended by the first portion 7, 70.
- the side of the first portion 7, 70 which is intended to be introduced first into the female element 6, 60 , 600 is advantageously extended by a convergent conformation 11, 110, for example having a substantially frustoconical shape.
- the male element 5, 50 has substantially the shape of a cylinder, for example of circular section, said cylinder being provided with a groove formed by removal around its periphery, said groove forming the second portion 8.
- first portion 7, 70 and the second portion 8 are in this case preferably carried out by a first shoulder 9 forming an annular planar surface.
- the second portion 8 thus extends between said p 'irst shoulder 9 and a second shoulder 10 separating the second portion 8 from the rest of the flexible band 2, said second shoulder 10 being located at the first end 3.
- first portion 7, 70 and / or the second portion 8 may have a substantially rigid character.
- first portion 7, 70 of the male element 5, 50 has a deformable character.
- the gastric band 1, 10 advantageously comprises a system for reversibly controlling the variation of its internal perimeter.
- Said system preferably comprises a flexible filiform element 12, 120 having good flexibility and good mechanical strength, said flexible filiform element 12, 120 being inserted longitudinally and sliding along the main axis of symmetry of the cylinder forming the main body of the ring 1, 10.
- said filiform element 12, 120 occupies a cavity connecting the first and second ends 3, 4, 40, 400 and extending substantially between said first and second ends 3, 4, 40, 400, that is to say substantially over the entire developed length of the ring 1, 10.
- the flexible filiform element 12, 120 is mounted to define a fixed portion 13, 130 which is secured using appropriate fastening means, for example involving a circlip and a washer, with the second end 4, 40, 400 of the ring 1, 10.
- the other end portion of the flexible filiform element 12, 120 forms a free portion 14, 140, that is to say capable of moving in translation relative to the fixed portion 13, 130.
- Said free portion 14, 140 is functionally associated with an actuator 15, 150 mounted on the ring 1, 10 towards or at the level of the first end 3.
- the actuator 15, 150 is responsible for transmitting the energy necessary to ensure, when activated, the reversible translation of the flexible element filiform 12, 120 relative to the fixed portion 13, 130, in order to obtain an associated variation in the perimeter of the ring 1, that is to say an increase or a reduction in its diameter.
- the actuator 15, 150 comprises an electric motor.
- the gastric band 1, 10 is particularly but not exclusively designed to be integrated into a system for restriction and remote control of the ingestion of food in the stomach of a patient, in such a way that you can control remotely, without any invasive surgical intervention, the variation of the diameter of the ring 1, 10.
- the electric motor 15, 150 forming an actuator is advantageously connected to a subcutaneous reception circuit provided with a reception antenna 16 (cf. FIG. 2) for receiving a radio-frequency control and power signal, the assembly being intended to be implanted in the patient's body.
- the converging conformation 11 is extended by a tapered sheath 11A including a part of the protective catheter 17.
- This tapered sheath 11 A like the conformation 11, is preferably made from a material of low hardness, by example in silicone of hardness equal to 40 Shore A. The choice of such a material of low hardness to produce the tapered sheath 11A allows the latter to be penetrated in its mass by the free end 14 of the filiform flexible element 12 when the latter moves under the action of the motor 15 (see FIG. 9).
- this protective catheter 17 could be made of silicone with a hardness equal to 80 Shore A.
- a catheter 17 of high hardness overmolded by a tapered sheath 11A of lower hardness makes it possible to find an excellent compromise flexibility / rigidity / resistance for this zone 99 of the ring 1 extending between the male element 5 and l reception antenna 16.
- This compromise makes it possible to give the area 99 a flexible contact capable of limiting, or even eliminating, any attack on tissues close to the stomach, while ensuring, thanks to the presence of a high hardness catheter, protection against possible crushing coming from the laparoscopic forceps used by the surgeon to grasp the area 99 and pull on the latter in order to achieve the closure of the ring 1.
- the presence of a tapered sheath 11A of low hardness also facilitates, by its soft nature, the grip by such laparoscopic forceps.
- the ring 1, 10 prefferably be provided with a system for varying its diameter produced by pneumatic means, for example by injecting or withdrawing a fluid through the catheter 17, which in this case acts as a fluid conduit between a source of fluid (connected in place of the antenna 16) and an inflation chamber formed within the flexible strip 2.
- the ring 1 is not provided with any means for varying its diameter.
- the first portion 7, 70 does not provide any housing or protection function for any actuation means, but simply assumes the role of a male closing element.
- the female closure element 6, 60, 600 is shaped to evolve, by elastic deformation, between on the one hand an elastic return configuration forming a closure configuration, and on the other hand a passage configuration, preferably reversibly.
- reversible is meant here that the female closure element can pass at will from its closed configuration to its passage configuration (and vice versa) without undergoing irreversible structural alteration, of the destruction kind.
- the closing configuration corresponds to a configuration in which the female element 6, 60, 600 forms and delimits a reduced opening 18, 180 allowing the passage of the second portion 8 of the male element 5, 50, but prohibiting, or at least opposing the passage of the first portion 7, 70 of the male element 5, 50.
- the female element 6, 60, 600 when the female element 6, 60, 600 is in the passage configuration, as for example illustrated in FIGS. 5 and 8, it forms an enlarged opening 19, 190 allowing the passage of the first portion 7, 70 of the male element 5, 50.
- the female element 6, 60, 600 is capable of being distended from a closed configuration to an open configuration, this distension being preferably caused by the passage in force of the first portion 7 , 70 whose section is greater than the section of the opening 18, 180 delimited by the female element 6, 60, 600 in the closed configuration.
- the female element 6, 60, 600 returns automatically, by elastic return, or more generally by shape memory, in its closed configuration, which configuration closure is notably illustrated in FIGS. 1 to 4, 6 and 7.
- the first portion 7, 70 thus forms a stop dimensioned to have a cross section greater than that of the opening reduced 18, 180, so that the closure of the ring is achieved by pressing the female element against said stop.
- the female element 6, 60, 600 comprises a structural discontinuity 20, 200, 2000 at which the deformability of the female element 6, 60, 600 is greater than that of the rest of the female element 6, 60, 600.
- structural discontinuity is meant here a notable spatial variation of the structure of the female element 6, 60, 600, said variation being preferably abrupt, but which can however also be relatively progressive.
- a structural discontinuity may thus consist of a variation in the mechanical properties of the material forming the female element 6, 60, 600, this notable change in properties being due for example to a variation in the composition of the constituent material of the female element, or of the creation in the female element 6, 60, 600 of empty zones, that is to say free of any material and therefore by nature "infinitely" deformable.
- the structural discontinuity 20, 200, 2000 is thus produced, in accordance with the invention, so that the deformation capacity of the female element 6, 60, 600 is greater at said discontinuity 20, 200, 2000 that substantially everywhere else in the rest of the female element 6, 60, 600.
- the female element 6, 60, 600 when the female element 6, 60, 600 is subjected to a given mechanical stress, the female element 6, 60, 600 will tend to deform substantially more easily at the level of the discontinuity structural 20, 200, 2000 than in any other zone belonging to said female element 6, 60, 600.
- the female element 6, 60, 600 thus has a spatial gradient of capacity for deformation, or even more simply a capacity for deformation which is substantially constant, except in certain singular zones corresponding to structural discontinuities 20, 200, 2000.
- the deformation of the female element 6, 60, 600 that is to say the change in the dimensions of this female element 6, 60, 600 and / or the alteration of its shape thus requires a mechanical level stress generally lower than the mechanical stress required to obtain the same size and / or shape changes in the absence of structural discontinuity 20, 200, 2000.
- This locking / unlocking means 21 A, 21 B, 210A, 210B, 2100A, 2100B thus makes it possible to block the female closing element 6, 60, 600 at will in its locking configuration, that is to say d 'prevent the female closure element 6, 60, 600 from passing into the passage configuration, even under the effect of untimely mechanical stress.
- the locking / unlocking means 21 A, 21 B, 210A, 210B, 2100A, 2100B is arranged to move between on the one hand a locking position (shown in Figures 3 and 7 for example), where it inhibits deformability at the structural discontinuity 20, 200, 2000, and on the other hand an unlocking position shown for example in Figures 1, 2, 6 where it substantially releases the female closure element 6, 60, 600 from any stress of locking.
- the female closure element comprises a ring 6 of generally substantially cylindrical shape with a circular base.
- the side wall 6A forming the body of the ring 6 thus extends longitudinally between a first and a second opposite face 6B, 60.
- the first slot 22 therefore extends over the entire length of the ring, throughout the thickness of the wall 6A.
- the section of the reduced opening 18 delimited by the ring 6 when the latter is in the rest position, that is to say without external mechanical stress, is substantially adjusted to the section of the second portion 8.
- the generally circular contour 18A delimiting the opening 18 is of diameter slightly greater, or even substantially equal, to the diameter of the cylindrical portion forming the second portion 8.
- the ring 6 prefferably defines a reduced opening 18, the cross section of which is not circular but of any other shape, for example rectangular.
- the shape of the cross section of the second portion 8 will be preferably adapted to be complementary to that of the reduced opening 18.
- the ring 6 is provided with a first gripping tab 23 arranged to facilitate the approximation and cooperation of the male element 5 and the ring 6, and / or the spacing and separation of said male 5 and female elements. 6.
- the first gripping tab 23 is preferably attached to the side wall 6A of the ring 6, and projects outwards from the closed loop formed by the flexible strip 2 (see FIG. 2), to facilitate bringing together or spacing of the ring 6 and of the male element 5, as well as the mutual connection or disconnection of said male 5 and female 6 elements.
- the first gripping tab 23 which preferably comprises as main body a substantially planar and rectangular tongue made of elastic material, extends between a fastening end 23A which is integral with the ring 6 and a free end of gripping 23B which is intended to be grasped by the surgeon using surgical pliers.
- this single resulting slot 22, 24 does not pass right through the first gripping tab 23, that is to say does not open out at its gripping end 23B, makes it possible to maintain relative stability and stiffness of the ring 6, which will thus permanently form (ie in its opening configuration as in its passage configuration) a closed collar (that is to say having a continuity of material) of variable diameter, while being split, preferably partially, to allow and facilitate the introduction of the male element 5.
- the flexible bracelet 25 is thus capable of being brought, by elastic deformation for example, in joint cooperation with said lugs 26A, 26B, so as to press and hold said lugs 26A, 26B against one another and prevent their separation , and therefore that of the lips 22A, 22B, which amounts to locking the ring 6 in the closed configuration.
- the bracelet 25 is provided with a second gripping tab 27 arranged to allow the approximation and cooperation of the bracelet 25 with the lug 26 and / or the separation and separation of said bracelet 25 and lug 26.
- the second grip tab 27 is advantageously has the form of a flat tongue attached to the external periphery of the flexible bracelet 25 substantially facing the lug 26.
- a hindrance for reversibly connecting the lips 22A, 22B is in the form of a cord 250 extending elongated between a first end 250A, secured to the lip 22B and a second free end forming an enlarged head 250B.
- Said head 250B is arranged to cooperate with an additional anchoring piece 250C secured to the other lip 22A.
- the cord 250 preferably has an elastic character, and is arranged in order to be able to move, preferably reversibly, between on the one hand a locking position shown in FIG.
- the surgeon first introduces the gastric band 1, endoscopically, into the patient's body.
- the ring 1 is in developed form, that is to say substantially elongated.
- the surgeon then proceeds to close the ring 1 by threading the antenna 16, followed by the sheath 17, the conformation 11 and the first portion 7, in the opening 18 of the ring 6, by the first face. 6B of the ring 6.
- the ring 6 will have excellent deformability during the passage of the first portion 7 of the male element 5, this deformation ability coming mainly first and second communicating slots 22, 24.
- the first portion 7 has passed entirely through the opening 18, 19 of the ring 6, the latter is then opposite the second portion 8, the section of which is substantially smaller than that of the first portion 7. Therefore , the ring 6 is no longer subjected to a deformation stress and can then automatically return to the closed configuration (cf. FIG. 4) thanks to the elastic nature of the material from which it is made.
- the ring 25 has only a residual elasticity, since its elastic properties have already been taken advantage of to pass from its unlocking configuration to its locking configuration.
- the ring 25 is thus able to exert a firm, or even substantially rigid, hooping around the first slot 22 to prevent any disjunction of the lips 22A, 22B.
- the ring 1 is thus closed and locked around the patient's stomach.
- This closed and locked configuration is particularly stable, since the ring 6 is clamped between the first and the second shoulders 9, 10 which prevent any lateral sliding of said ring 6.
- FIG. 6 differs from the first embodiment only in the conformation of the female element 60.
- the ring 60 is also provided, like the ring 6 used in the first alternative embodiment, with a straight slot 220 formed longitudinally throughout the thickness of the side wall 60A, and opening at the first and second faces 60B, 60C between which the ring 60 extends longitudinally.
- the ring 60 is provided on either side of said first slot 220, with a respective half-button 28, 29, said two half-buttons 28, 29 substantially forming a single resulting button 60 when the ring is in closed configuration, as shown in FIG. 6.
- Said resulting button 28, 29 is intended to cooperate with a corresponding buttonhole 31 A for locking the ring 60 in the closed configuration, said half-buttons 28, 29 and buttonhole 30 thus forming the locking / unlocking means 210A, 210B.
- the buttonhole 31 A is formed by a slot made in a third gripping tab 31, which tab is attached to the ring 10, preferably towards the first end 3, and more precisely towards the male element 5.
- the third gripping tab 31 makes it possible to bring the buttonhole 31 A into locking cooperation with the resulting button 28, 29 and / or makes it possible to separate, if necessary, said buttonhole 31 A from the resulting button 28, 29.
- the third grip tab 31 extends substantially parallel to the plane of the first face 60B of the ring 60, and towards the outside of the ring 10 when the latter forms a closed loop, as illustrated in FIG. Figure 6.
- said third gripping tab 31 is itself provided with a fourth gripping tab 32 which extends substantially perpendicular to and from the third gripping tab 31, substantially tangentially to the ring 10 when the latter forms a closed loop.
- Said fourth gripping tab 32 also extends in the direction opposite to that of the resulting button 28, 29, this fourth tab 32 making it possible to facilitate the opening / closing and locking / unlocking operations of the ring 10.
- FIGS. 7 and 8 a third variant embodiment of the invention will be described, which is illustrated in FIGS. 7 and 8.
- This third variant variant differs from the previous two only by the particular conformation of its closure element 600, which is also a ring .
- the ring 600 which extends longitudinally between a first and a second opposite face 600B,
- the first slot 2200 is made up of at least three elementary slots, namely a first and a second straight elementary slots 2200A, 2200B linked together by a connecting slot 2200C.
- Said first elementary slot 2200A is formed longitudinally in the side wall 600A from the first face 600B to substantially half the length separating the first face 600B from the second face 600C.
- the second elementary slot 2200B is in turn formed longitudinally from the second face 600C to substantially half the length separating said first and second faces 600B, 600C.
- the connecting slot 2200C extends laterally on the periphery of the ring 600 substantially perpendicular to said first and second elementary slots 2200A, 2200B and in the extension of each of these elementary slots 2200A, 2200B, to form with them a single resulting slot, which constitutes the first slot 2200.
- the first slot 2200 is in the form of two stair treads 2200A, 2200B, separated by a counter step 2200C.
- the particular shape of the first slot 2200 thus makes it possible to provide in the ring 600 two independent flexible arms 33, 34 which are capable of moving by deformation to widen the opening 180, in order to obtain an enlarged opening 190.
- the ring 600 is also provided with first and second locking tab 35, 36 forming locking means 2100A, 2100B.
- Said legs 35, 36 are located respectively on either side of the connection slot 2200C, so that each of the legs 35, 36 is attached respectively to one of the arms 33, 34.
- Each locking tab 35, 36 is also provided with respective hooking and blocking means 37A, 37B, 38A, 38B allowing interlocking in position of said tabs 35, 36 when the ring 600 is in the closed configuration, and that it encloses the second portion 8 of the male element 5.
- the locking tabs 35, 36 extend substantially radially outward from the ring 600, from the side wall 600A of the latter.
- Each locking tab 35, 36 is provided with two lateral complementary tabs 37A, 37B, 38A, 38B integral with the locking tabs 35, 36, so that each pair of complementary tabs 37A, 37B, 38A, 38B substantially forms a " U ”with the respective locking tab 35, 36 associated therewith.
- the arms of the "U” are formed respectively by the complementary tabs 38A, 38B while the core of the "U” is formed by the locking tab 36 itself.
- one of the arms 37A relating to the gripping tab 35 is interposed between the arms 38A, 38B of the "U" relating to the locking tab 36.
- This particular arrangement thus makes it possible to obtain a locking of the ring 600 in the closed configuration.
- This lock is made again more reliable by the cooperation of the first and second faces 600B, 600C of the ring 600 with the first and second shoulders 9, 10 of the male element 5.
- the surgical ring 1, 10 according to the invention makes it possible to obtain an excellent compromise between on the one hand the effort necessary to achieve its closure and on the other hand the blocking behavior of the male / female elements achieving this closing.
- the implantable surgical ring 1, 10 according to the invention is moreover extremely simple to manufacture, according to all the techniques well known to those skilled in the art, and for example by molding in an elastomeric material of the silicone type. More particularly, the ring 1, 10 has a one-piece character.
- the invention finds its application in the manufacture and use of surgical rings for the treatment of obesity.
