Device for performing or preparing for a mitral valve annuloplasty by a transfemoral approach

Abstract

The device () is intended to be positioned in a sealed introducer placed in a femoral vein in order to penetrate the left atrium () of the heart () by passing through the septal wall () thereof. The device comprises an assembly for cooperating with a handle under the control of control means for actuation of the assembly, for placing and fixing a reinforcement ring () on the mitral valve (), said assembly being arranged at the end of a manipulation rod () and comprising: a bearing member () comprising a plurality of arms () connected pivotably to the end of the rod () so as to change, under the action of the control means, from a position folded along the rod () to a deployed position spaced apart from the rod (), in order to bear under the mitral valve () in a manner uniformly distributed along the periphery of the mitral valve; a counter-bearing member () comprising a plurality of arms (), at the free end of which arms () the reinforcement ring () is arranged, the arms () are connected pivotably to a support () disposed coaxially with respect to the rod () in such a way as to change, under the action of the control means, from a position folded along the rod () to a deployed position spaced apart from the rod (), in order to realize the counter-bearing on the mitral valve and to position the reinforcement ring (); means for removing sutures for fixing the reinforcement ring () to the mitral valve.
