Abstract

he invention relates to a dividable mechanical heart valve device composed of two subsidiary articulated constructional elements: a) one external steady ring 1 composed of two subsidiary members (1.i, 1.ii); b) one internal moving ring 2 connected with the steady one with a connecting wire 3. The external element is composed of a circular metal ring featuring a female fluting and an opening (1.i), and of a second fabric ring (1.ii). The internal section 2 is composed of a metal ring and movingsemi-circular wings closeable by snap action. After the implantation of the valve, first the external and then the internal ring should be fixed in place. Furthermore, in case of post-operative problems, the internal ring can be removed, replaced orre-implanted with no removal of the whole heart valve.
