| 摘要 |
The invention concerns an intraparietal reinforcing device (1) designed to incorporated in a biological valve replacement comprising a biological heart valve (10) whereof the valvular plane is formed by leaflets (11a, b, c) laterally attached to an outer tubular wall (12) by the commissures (13), as well as a biological prosthesis provided with such a device. The device is adapted to be set inside the organic tissue of the heart valve (10) by comprising a base (3) and a stabilizing part (2) mounted on the base (3) and adapted to be inserted inside the outer tubular wall (12) of the heart valve (10) and to reinforce the structure thereof so as to maintain the shape of the heart valve (10) after implantation. The stabilizing part (2) comprises at least two intraparietal rods (2a, 2b) adapted to be inserted in the organic tissue of the heart valve (10), said intraparietal rods (2) being positioned on the base (3) so as to be, once the device set on the heart valve (10), laterally offset relative to the point of intersection of the outer tubular wall (12) with the commissures (13) of the heart valve (10) and the valvular plane of the heart valve (10) of the valve replacement.
