Heart valve prosthesis
First Claim
1. An atrio-ventricular valve prosthesis comprising:
- a ring-shaped supporting structure to be anchored at the valve annulus; and
a single extended valve leaflet having a free end and a root end, made of flexible material floatingly supported by the supporting structure allowing for a movement of the free end within the supporting structure,wherein the supporting structure includes,a support wall portion at which the root end of the valve leaflet is connected, anda complementary wall portion opposite to the support wall portion having a coaptation surface configured to be sealingly engaged with the free end of the valve leaflet, and extending in a direction substantially parallel to a movement direction of the free end of the valve leaflet at the coaptation surface,wherein the free end of the valve leaflet is connected to the support wall portion or to the complementary wall portion by a traction member of flexible material having a length that the movement of the free end of the valve leaflet is stopped at the coaptation surface.

Abstract
Heart valve prosthesis, comprising a ring-shaped supporting structure (3) to be anchored at the valve annulus, and a valve leaflet (5) supported by the supporting structure. The supporting structure comprises a support wall portion (31), at which a root end (51) of the valve leaflet is connected, and a complementary wall portion (32) opposite the support wall portion, which supports a coaptation surface (33) adapted to be sealingly engaged by a free end (52) of the valve leaflet (5), and extending in a direction parallel to the direction of movement of the free end (52) of the valve leaflet (5) at the coaptation surface (33). The free end of the valve leaflet (5) is connected to the support wall portion or to the complementary wall portion by means of a traction member (55), dimensioned in such a way that the free end (52) of the valve leaflet (5) is stopped at the coaptation surface.
