Abstract

Abstract Translated from French L'invention concerne les prothèses destinées à remplacer les valvules cardiaques et leur procédé de fabrication. La prothèse est faite à partir d'un morceau plat d'une membrane biologique stabilisée 2, le morceau plat étant plié suivant une ligne de pliage 5 et étant fixé par des coutures 3 et 6 à un matériau de base non biologique souple plat 1 afin de former une lamelle 4. Le bord actif de la valvule étant obtenu par pliage et non par découpage, la valvule ne présente aucune tendance à se détériorer à cet endroit. The invention relates to prostheses intended to replace heart valves and a method of making them. The prosthesis is made from a flat piece of a stabilized biological membrane 2, the flat piece being folded along a fold line 5 and being secured by seams 3 and 6 to a flat flexible non-biological base material 1 in order to to form a lamella 4. The active edge of the valve being obtained by folding and not by cutting, the valve has no tendency to deteriorate at this location.
