Tubular support for setting, by percutaneous route, a substitution cusp

Abstract

This support (1) comprises a structure capable of being contracted radially to allow the introduction of the support (1) - valve (2) assembly into the patient's body, and of being deployed to allow the support to be taken of this structure against the wall of the site to be fitted with the valve. According to the invention, the structure of the support (1) comprises: an axial portion (3) of the valve support (2), having a structure in wire or network of wires suitable for bearing against the cardiac ring (10) remaining after removal of the deficient native valve; at least one axial wedging portion (4), having a wire or wire network structure distinct from the structure of said axial portion (3) of valve support, and of diameter greater than the diameter of said axial portion (3) allowing it to bear against the wall bordering said remaining cardiac ring (10); and at least one wire (5) punctually connecting said portions (3, 4).

  1. 1
    CLAIMS REVENDICATIONS 1 - Tubular support for the placement, by percutaneous route, of a replacement heart valve (2), comprising a wire structure or network of wires capable of being contracted radially to allow the introduction of the support assembly ( 1) - valve (2) in the patient's body, by means of a catheter, and to be deployed to allow the bearing of this structure against the wall of the site to be fitted with the valve (2); 1 - Support tubulaire de mise en place, par voie percutanée, d'une valve cardiaque de remplacement (2), comprenant une structure en fil ou en réseau de fils susceptible d'être contractée radialement pour permettre l'introduction de l'ensemble support (1) - valve (2) dans le corps du patient, au moyen d'un cathéter, et d'être déployée pour permettre la prise d'appui de cette structure contre la paroi du site à équiper de la valve (2) ; support (1) caractérisé en ce que sa structure comprend :support (1) characterized in that its structure comprises: - an axial portion (3) of valve support (2), having a wire structure or network of wires suitable for receiving the replacement valve (2) mounted on it, and suitable for bearing against the cardiac ring ( 10) remaining after removal of the deficient native valve;- une portion axiale (3) de support de valve (2), présentant une structure en fil ou en réseau de fils propre à recevoir la valve de remplacement (2) montée sur elle, et propre à prendre appui contre l'anneau cardiaque (10) subsistant après le retrait de la valve native déficiente ;- At least one axial wedging portion (4), having a wire or network of wires structure distinct from the structure of said axial portion (3) of valve support, and of which at least one part is present in the state deployed, a diameter greater than the diameter in the deployed state of said axial portion (3) of the valve support, such that this axial wedging portion (4) is able to bear against the wall bordering said remaining cardiac ring (10) ;and - au moins une portion axiale de calage (4), présentant une structure en fil ou en réseau de fils distincte de la structure de ladite portion axiale (3) de support de valve, et dont au moins une partie présente, à l'état déployé, un diamètre supérieur au diamètre à l'état déployé de ladite portion axiale (3) de support de valve, tel que cette portion axiale de calage (4) est propre à prendre appui contre la paroi bordant ledit anneau cardiaque subsistant (10) ;et - at least one wire (5) connecting said portions (3, 4), this or these son (5) being punctually connected to these portions (3, 4), so as not to obstruct the deployment of said axial portions ( 3, 4) according to their respective diameters. - au moins un fil (5) de liaison desdites portions (3, 4), ce ou ces fils (5) étant reliés ponctuellement à ces portions (3, 4), de manière à ne pas faire obstacle au déploiement desdites portions axiales (3, 4) selon leurs diamètres respectifs.
