    DETAILED PRESENTATION OF THE INVENTION
    The invention relates to a device (1) for performing a surgical operation consisting in repairing broken or elongated cords of a mitral valve (2), for example in the case of a mitral prolapse.
    The device (1) is intended to be positioned in a sealed introducer of any known and appropriate type (not shown) and with a diameter less than or equal to 12 mm, placed in a femoral vein to ascend and penetrate the left atrium (3) a heart (4) passing through its septal wall.
    Referring to Figures 1 to 8, the device (1) comprises a first handling rod (5), at the end of which is arranged a first assembly (6) for the establishment and fixing of an artificial rope (7) on the pillar (8) of a broken rope. The other end of the first rod (5) is intended to cooperate with a handle subject to control means, not shown, for example in the form of a trigger for the actuation of the first assembly (6). The device (1) according to the invention allows, under ultrasound control and possibly also radiography, after having ascended the vena cava, to penetrate the first set (6) into the left atrium (3) of the heart (4) while passing through the septal wall. Then, when the first set (6) is in the left atrium (3) of the heart (4), it is able to pass through the mitral valve (2) to come opposite the pillar (8) of the cord broken (see Figure 2). The carrying catheter can be temporarily stiffened with the ideal curvature to work opposite the plane of the mitral valve.
    The head of the first rod (5), constituted for example by an atraumatic warhead, is retractable to reveal internally an elastic clip (9) pivotally and removably connected to the end of the rod (5). The elastic clip (9), secured to the handle control means, is capable of passing, under the action of said control means, from a folded position along the rod (see FIGS. 2 and 6) to a tilted orthogonally position (see Figures 3, 4, 7, 8). To this end, the elastic clip (9) is received in a base (10), itself pivotally mounted about an axis (11), under the actuation of the control means. These control means, not shown, for example include sets of cables, connected to a part of the base (10), opposite to the clip (9), to pull or press on this rear part and to pivot the base (10) around its axis (11).
    With reference to FIGS. 9 and 10, the clip (9) comprises two elastic branches (9a), brought together, with hooked end portions (9b) for anchoring as such . Referring to Figures 6 to 8, the clip (9) is held in the base (10) by means of two arms (12) disposed between the elastic arms (9a) of the clip (9), and articulated around a pivot, in particular around the axis (11) so as to pass, under the action of the control means, from a position close to one another (cf. FIGS. 6, 7, 15 ) in a separated position by forcing the spacing of the branches (9a) of the clip (9) to cause it to open. The pivoting of the arms (12) is carried out by the pivoting of the base (10).
    The attachment of the clip (9) to the pillar (8) of the broken cord (see FIG. 4) makes it possible to maintain a sufficient distance between the elastic branches (9a) of the clip (9), creating a play by relative to the arms (12) which constitute means for opening and unlocking the clip (9), allowing said arms (12) to retract and release the removable clip (9) (cf. FIG. 5) .
    Referring to Figure 5, the artificial cord (7) is knotted to the clip (9) and goes back inside the first rod (5) so that after removal of said rod, the artificial cord (7 ) goes up along the femoral vein.
    Referring to Figures 12 to 28, the device (1) according to the invention also comprises a second assembly (13) able to cooperate with a handle, which can be the same handle as that of the first assembly (6), subject to control means for actuating this second assembly (13) for the establishment and fixing of the artificial cord (7) to a sheet (2a) of the valve (2).
    In the same way as for the first set (6), the second set (13) is intended to go up the vena cava, and to penetrate into the left auricle (3) of the heart (4) while passing through the wall septal, in particular by following and sliding along the artificial cord (7) already present.
    The second assembly (13) is arranged at the end of a second handling rod (14) and comprises fixing means (9, 16), pivotally connected to the end of the rod so as to pass, under the action of the control means, from a folded position ίο along the rod (14) (see Figure 11) to a tilted position (see Figures 12, 15 to 18, 21 and 23 to 27) to fix the artificial cord (7) to the sheet (2a) of the valve (2).
    From this concept, several embodiments of the invention have been imagined.
    According to a first embodiment, in particular illustrated in FIGS. 11 to 15, the means for fixing the artificial cord (7) to the sheet (2a) are in the form of a staple (9), similar to that of the first set ( 6), and which is intended to be anchored on the pillar (8) of the broken rope. In the same way, this second clip (9) is received in a base (10) pivotally mounted about an axis (11) to pass from a folded position along the second rod (14) (Cf. figure 11 ) in an angularly tilted position (see FIG. 12, 15) in order to be anchored on the sheet (2a) of the mitral valve (2). Arms (12) are arranged between the elastic branches (9a) of this second clip (9), to form unlocking locking means, in the same way as with the first clip (9). The second clip (9) is therefore designed to open and come to anchor on the sheet (2a). When the clip (9) is anchored on the sheet (2a), the arms (12) can be retracted to release said clip (9).
    The second clip (9) is connected to the artificial cord (7). To do this, and with reference to FIGS. 13 and 14, the second clip (9) comprises, for example, a wire (15) which forms a loop around the artificial cord (7). This loop allows in particular said second clip (9) and the second assembly (13) to slide along the artificial cord (7). In this configuration, the artificial rope (7) can be tied around the loop and stretched to complete the rope repair operation. The artificial cord (7) is therefore fixed to the pillar (8) and the sheet (2a) by means of clips (9).
    According to a second example not illustrated, the artificial cord (7), which is for example in the form of a nonabsorbable polyamide or teflon suture, can be notched. In this configuration, the clip (9) of the second set (13) can comprise any suitable means, such as a rack, for sliding along said artificial rope (7) notched and only in the direction of the clip (9) of the first set (6). In other words, when the second clip (9) is anchored on the sheet (2a), the tension of the artificial cord (7) is adjusted by sliding the second clip (9) along the notched artificial cord (7) .
    The anchoring of the second clip (9) on the sheet (2a) of the valve (2) can be facilitated by means of a stabilizing clamp, not shown, similar to the clamp (16) which will be described below. . For this purpose the second assembly (13) comprises such a clamp pivotally connected to the end of the second rod (14) so as to pass, under the action of the control means, from a folded position along the rod (14) in a position regularly tilted to the rod (14), that is to say parallel to the sheet (2a) of the valve (2), and from an open position to a closed position for pinching and stabilize the sheet (2a) for anchoring the second elastic clip (9).
    The fixing of the artificial cord (7) to the sheet (2a) of the valve (2) can be carried out in a different way. Indeed, with reference to FIGS. 16 to 28, instead of a second clip (9), the means for fixing the second assembly (13) may comprise a clamp (16) pivotally connected to the end of the second rod (14) so as to pass, under the action of the control means, from a folded position along the rod (14) (cf. FIG. 22) to an angularly tilted position (cf. FIGS. 16 to 18, 21 and 23 to 27), in particular parallel to the sheet (2a) of the valve (2). This clamp (16) is designed to pass from an open position to a closed position to clamp the sheet (2a), by the action, for example, of push and / or push cables. The clamp (16) is connected to the artificial cord (7) to slide along it when the second set (13) is introduced into the left atrium (3) of the heart (4). For this purpose, the clamp (16) comprises an upper jaw (16b), and a lower jaw (16a) equipped with a valve (17) articulated to adopt a closed position (see Figures 22 to 26) in which it encloses and maintains the artificial cord (7), while allowing the gripper (16) to slide around and along said artificial cord (7), and an open position (see FIGS. 21 and 27) for releasing the artificial cord (7 ).
    Figures 21 to 28 illustrate the different steps implemented by the device in the steps illustrated in Figures 16 to 20. With reference to these figures, the clamp (16) is intended to pinch the sheet (2a) (Cf. figures 17 and 24), while being connected to the artificial cord (7). The jaws (16a, 16b) of the clamp (16) are both perforated to allow a needle (18), which is arranged inside and along the second manipulation rod (14), to move to drill and cross the thickness of the sheet (2a) of the valve (2) (see Figures 25).
    The needle (18) fixes the artificial cord (7) to the sheet (2a) of the mitral valve (2). To do this, the needle (18), after having crossed the sheet (2a) can grasp the artificial cord (7) maintained by the valve (17), and be withdrawn to make the artificial cord (7) pass through said sheet (2a) for fixing it, in particular by knotting.
    The needle (18) therefore has means for gripping the artificial cord (7), for example in the form of an inclined notch forming a hook at the end of the needle (18).
    According to another technique, illustrated in FIGS. 18 to 20 and 26 to 28, the needle (18) has internally a suture (19) with shape memory, capable of being extracted to pass through the thickness of the sheet (2a), and forming a loop, again crossing the thickness of the sheet (2a), to attach the artificial cord (7) to said sheet (2a).
    In this latter configuration, and with reference to FIGS. 19-20 and 27-28, the artificial cord (7) is fixed to the pillar (8) by means of a clip (9), and to the sheet (2a) by through a shape memory suture (19), forming a loop.
    The characteristics of the device (1) according to the invention provide numerous advantages over existing solutions. Going through the transfemoral route reduces the duration and invasiveness of the operation. Note that the staples (9), and the clips (16) used are radio-opaque, or else include radioopaque and / or ultrasound markers allowing the surgeon to perform a 2D or 3D control of their position, as and as the operation progresses. Advantageously, the staples (9) used are sheathed in textile to facilitate their rehabilitation by human tissue.
