1. An intervalvular implant (1) for a mitral valve (100) wherein the implant (1) has a structure formed by a frame (2) and by a membrane (3) covering this frame;

  • the frame (2) has;

    an elongated base portion (5) formed by two curved or chevron branches (10), these branches (10) having median portions distant from each other and end portions which run while getting closer to each other and being connected to connecting areas (6) located at the longitudinal ends of the base portion (5);

    this elongated base portion (5) has a width extending from the median portion of one branch (10) to the median portion of the other branch (10) and a length extending from one connecting area (6) to the other connecting area (6), and is so elongated that said length is three to eight times greater than said width;

    anchoring portions (7) connected to these connecting areas (6), allowing the implants (1) to be anchored to the annulus (102) of the mitral valve (100) in two points of the annulus (102) spaced from one another, in particular opposite one another;

    a longitudinal hoop (8) extending from one connecting area (6) to the other;

    the membrane (3) is flexible and extends from one branch (10) to the other while passing near the hoop (8), this membrane being connected to said branches (10) without being stretched between these branches (10) and this hoop (8) so that the two lateral portions (3a) of the membrane (3) thereby formed on both sides of the implant are able to adopt either a concave shape, outwardly convex, or a recessed shape, outwardly concave.
