ABSTRACT:
A method of producing flexible closing members, especially artificial heart valves, and a flexible closing member, especially an artificial heart valve, which can be produced according to such a method. According to the method of producing the housing of the closing member is radially expanded, the closing element of the closing member is formed as substantially plane two-dimensional element, and the plane two-dimensional element is connected to the housing in the expanded condition of the same. This method is preferably realized as dip method according to which the closing element is shaped and formed to the housing in a single working step. The described flexible closing member is an artificial three-sail heart valve which is characterized by a special shape of the three closing elements.
