Intraparietal reinforcing device for biological cardiac prosthesis and reinforced biological heart valve prosthesis
First Claim
1. 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.

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.

16. A bioprosthetic valve comprising:
-
a cardiac valve obtained from a heart, the cardiac valve comprising a plurality of leaflets and a valve wall, the valve wall having a wall thickness, each leaflet being attached to the valve wall in a natural configuration, each leaflet being attached to an adjacent leaflet at a commissure, the commissure being attached to the valve wall at an intersection, the cardiac valve defining a circumference and a flow axis; and an intraparietal reinforcement inserted within the valve wall near the intersection and extending into the wall thickness, the intraparietal reinforcement comprising a first shaft and a second shaft extending generally parallel to the flow axis, the first shaft being laterally offset from the commissure in a first direction along the cardiac valve'"'"'s circumference, the second shaft being laterally offset from the commissure in a second direction along the cardiac valve'"'"'s circumference, the second direction being opposite the first direction. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
