| titleOfInvention | MANUFACTURING PROCEDURE OF A VALVULAR PROTESIS FOR THE HEART. |
| abstract | A method of performing a cardiac valve prosthesis that includes a substantially cylindrical structure that defines a blood flow axis substantially parallel to the blood flow through the valve prosthesis and at least two flexible leaflets attached to the structure, the method comprising: forming at least two portions of scalloped edge in the structure, the shape of each scalloped edge portion being defined by the intersection of the structure with an inclined plane relative to the axis of blood flow; treat the structure to increase its surface energy to above 64 mN / m; provide a forming element that has at least two leaflet formation surfaces; couple the training element to the structure; applying a coating on the structure and the coupled forming element, the coating joining the structure, the coating forming on the leaf-forming surfaces the at least two flexible leaflets, the at least two leaflets being configured to be movable from a position open to a closed one, the at least two valves having a blood inlet side and a blood outlet side, the at least two valves being in the closed position when fluid pressure is applied to the outlet side, being in the position open when fluid pressure is applied to the inlet side and being in an intermediate neutral position between the open and closed position in the absence of fluid pressure applied to the leaflets, each leaflet having a fixed edge attached to a respective scalloped edge part of the structure and extending a free edge substantially between the tips of two posts, including the at least two leaflets a first mere leaflet that has a surface contour such that, when the first leaflet is in the neutral position, an intersection of the first leaflet with at least one plane perpendicular to the axis of the blood flow forms a first composite wave, the first composite wave being defined substantially by a first wave combined with at least a second superimposed wave, the first wave having a first frequency, the second wave having a second frequency, the first frequency being different from the second frequency, the first wave comprising a circular arc, in the that an angle included between the free edges of the leaflets at the corners of the valves is in the range of 10 ° to 55 °; and decoupling the structure formation element. |
