This material comprises an annuloplasty member able to be introduced using a catheter through minimally invasive vascular access, then to be delivered by said catheter and fixed to the valve annulus. According to the invention, it includes at least one catheter comprising at least one guide member able to be deployed from said catheter such that it extends along one portion of the valve annulus of the valve, in the immediate proximity of said valve annulus, and an implant having a helical shape engaged on said guide member, connected, with separation possibility, to actuation means making it possible to cause this implant to move forward while driving it in rotation around its axis; the implant can thus be deployed from the catheter while being simultaneously moved forward and driven in rotation along its axis.

Material for treatment of a heart valve, in particular a mitral valve

Implants formed by a helically wound wire and methods of using same for the treatment of a mitral heart valve. According to the invention, it has dimensions such that it is able to be screwed into the wall of the annulus and/or into the cardiac wall adjoining the annulus such that a portion of the annulus and/or of the wall is located in the perimeter of the implant; and it comprises at least one first coil able, during said screwing of the implant, to insert itself into the wall while having a first dimension and at least one second coil having a second dimension, or adopting this second dimension after implantation, the second dimension being smaller than the first dimension such that the implant, once inserted, enables contraction of the wall portion located in the perimeter of the implant.

Implant for treatment of a heart valve, in particular a mitral valve, material including such an implant, and material for insertion thereof

This implant () is formed by a helically wound wire (). According to the invention, it has dimensions such that it is able to be screwed into the wall of the annulus () and/or into the cardiac wall () adjoining this annulus () such that a portion of said annulus () and/or of said wall () is located in the perimeter of the implant (); and it comprises at least one first coil able, during said screwing of the implant (), to insert itself into said wall while having a first dimension and at least one second coil having a second dimension, or adopting this second dimension after implantation, said second dimension being smaller than the first dimension such that the implant (), once inserted, enables contraction of said wall portion located in the perimeter of this implant ().

This material comprises an annuloplasty member () able to be introduced using a catheter () through minimally invasive vascular access, then to be delivered by said catheter and fixed to the valve annulus (). According to the invention, it includes at least one catheter () comprising: &#x2014;at least one guide member () able to be deployed from said catheter () such that it extends along one portion of the valve annulus () of the valve (), in the immediate proximity of said valve annulus, and &#x2014;an implant () having a helical shape engaged on said guide member (), connected, with separation possibility, to actuation means () making it possible to cause this implant () to move forward while driving it in rotation around its axis; the implant () can thus be deployed from the catheter () while being simultaneously moved forward and driven in rotation along its axis, said rotation enabling the implant () to penetrate the tissue of the valve annulus () while being guided along said annulus by said guide member ().

An apparatus for treating a heart valve apparatus includes at least two anchoring elements designed to be anchored at the annulus and/or heart wall of the valve to be treated. Each anchoring element has a support surface. At least one linking element includes a central branch and two curved side branches, one of which is designed to be engaged on the support surface of an anchoring element, while the other is designed to be engaged on the support surface of another anchoring element, the linking element then being designed to be pivoted to a position such that the anchoring elements interconnect and in which the ends of the central branch are located in the vicinity of the support surfaces.
