DEVICE FOR REALIZING OR PREPARING MITRAL ANNULOPLASTY BY TRANSFEMORAL PATHWAY

摘要

The device (1) is intended to be positioned in a sealed introducer disposed in a femoral vein to enter the left atrium (4) of the heart (3) through its septal wall (5). The device comprises an assembly adapted to cooperate with a handle subject to control means for actuating the assembly for the establishment and fixing of a reinforcing ring (7) on the mitral ring (2) , said assembly is arranged at the end of a handling rod (6) and comprises: - a support member (8) comprising a plurality of arms (8a) pivotally connected to the end of the rod ( 6) so as to pass, under the action of the control means, a folded position along the rod (6) to an extended position spaced from the rod (6) to bear under the mitral ring (2). ) uniformly distributed along the periphery of the mitral valve; - a counter-support member (12) comprising a plurality of arms (12a), at the free end of which is arranged the reinforcing ring (7), the arms (12a) are pivotally connected to a support ( 13) arranged coaxially with the rod (6) so as to pass, under the action of the control means, a folded position along the rod (6) to an extended position spaced apart from the rod (6) to realize counter-support on the mitral ring and position the reinforcement ring (7); suture extraction means for fixing the reinforcing ring (7) on the mitral ring.
