  • Patent number: 7927369
    Abstract: An intraparietal reinforcing device is designed to be integrated into a biological valvular prosthesis consisting of a biological cardiac valve having a valve plane formed by leaflets attached laterally to an external wall along commissurae. The device can be placed in the organic tissue of the valve, and includes a base and a stabilizing part mounted thereon. The device can be inserted inside the external wall of the valve to reinforce the valve's structure and to maintain the valve's shape after implantation. The stabilizing part includes at least two intraparietal shafts, designed to be inserted into the valve tissue and positioned on the base so that, once the device is put in place on the valve, they are displaced laterally to the intersection point of the intersection line of the external wall with the commissurae and of the valve plane. A biological prosthesis may be provided with such a device.

  • Publication number: 20110022167
    Abstract: A reinforcement device for a biological valve includes an arrangement of supports configured to establish a double-trigone geometry in the valve and coupled to a base upon which the valve may be mounted. A plurality of commissural supports establish the geometry of a commissural trigone, and a plurality of intercommissural supports establish the geometry of an intercommissural trigone. A method for reinforcing a biological valve includes using commissural supports in conjunction with intercommissural supports, both sets of supports coupled to a base upon which the valve is mounted.
