Device for carrying out a transapical mitral valve annuloplasty
First Claim
1. A device for carrying out a transapical mitral valve annuloplasty, and adapted to be positioned in a sealed introducer arranged in a thoracic cavity between two ribs in order to penetrate into a left ventricle, passing through an apex of a heart, characterized in that the device comprises a body having a handle, an assembly that installs and secures a braid to a mitral ring with sutures, and at least one control member connected to said assembly enabling the extraction of said sutures through a mitral valve, said assembly comprising first and second portions arranged to anchor the braid to a periphery of a mitral annulus by exerting two opposing pressure-bearing forces with the first and second portions to clamp said sutures, characterized in that the assembly comprises a tubular arm including the first and second portions which can be separated after introduction into the left ventricle, the first portion receiving the sutures and being adapted to be brought into contact in a commisure between the mitral valve and a wall of the left ventricle, the second portion receiving the braid, and being adapted to pass through the mitral valve and to be positioned at right angles relative to an end of the first portion.

Abstract
The device is intended to be positioned in a sealed introducer arranged in the thoracic cavity between two ribs in order to penetrate into the left ventricle, passing through the apex of the heart. According to the invention, the device includes a body having a handle and at least one control member capable of acting on an assembly for installing and securing a braid to the mitral annulus by means of suturing elements, the assembly has a mechanism capable of enabling the extraction of a suture through the mitral valve while also being capable of enclosing the braid and becoming anchored to the periphery of the mitral annulus under the clamping effect of the suture, exerting two opposing pressure-bearing forces.
