Patent ID: 7927369

Claim:
Intraparietal reinforcing device designed to be integrated into a biological valvular prosthesis comprising a biological cardiac valve comprising organic tissue, in which the valve is composed of leaflets attached laterally in a natural configuration to an external tubular wall along commissurae, the external tubular wall having a thickness, the device comprising: a base; and a stabilizing part mounted on the base, the stabilizing part being designed to be inserted into the tubular external wall of the cardiac valve and designed to reinforce the structure of the cardiac valve in a way to maintain the shape of the cardiac valve after implantation, wherein the stabilizing part includes at least two intraparietal shafts designed to be inserted into the organic tissue of the cardiac valve and to extend into the thickness of the external tubular wall after insertion, the intraparietal shafts positioned on the base in a way that, once the stabilizing part is placed within the organic tissue of the cardiac valve, the shafts are displaced laterally to an intersection point of an intersection line of the tubular external wall with the commissurae of the cardiac valve and of the valvular plane of the cardiac valve of the valvular prosthesis.
