Abstract
A vessel valve including a sleeve or ring having a central opening and openable and closeable flap elements intended to allow the flow of blood through the central opening in one direction, whereas the flap elements are designed as circle segments, and the sector angle is
wherein n is a number of circle segments and is equal to 3, 4, 5 or 6, and wherein each flap element at its outer edge is pivotably connected to an inwardly directed flange on the inside of the ring so that in a closed position they co-operate to form a sealing body and in an open position they allow free passage of blood. The ring is composed of n sections, whose pair-wise juxtaposed ends form recesses in the flange accommodating hinge elements which are arranged in the middle of the outer edge of each of the flap elements and which with assembled sections are locked by undercutting; and a method for the manufacture of such vessel valve.
