Abstract

A heart valve prosthesis with a valve housing in the form of a ring and a curved valve which is mounted within the housing and which is hinged to the valve ring by means of a flat flexible small lug which, if appropriate, is drawn in one region through a slot in the valve ring, is characterized in that the valve and the ring each consist of two rigidly joined halves fitting respectively onto or into each other, and the end portions of the small lug in the form of a short strip are embedded "sandwich"-like between the valve halves on one side and between the ring halves on the other side.
