Cardiac-valve prosthesis

A cardiac-valve prosthesis (1), which can be used, for example, as valve for percutaneous implantation, comprises an armature (2) for anchorage of the valve prosthesis in the implantation site. The armature (2) defines a lumen for passage of the blood flow and supports a set of leaflets (3) comprising prosthetic valve leaflets (3a, 3b, 3c), which, under the action of the blood flow, are able to move into a radially divaricated condition to enable the flow of the blood through said lumen in a ...

The armature defines a lumen for passage of the blood flow and supports a set of prosthetic valve leaflets, which, under the action of the blood flow, are able to move into a radially divaricated condition to enable the flow of the blood through the lumen in a first direction and a radially cont...

Cardiac-valve prosthesis

A cardiac-valve prosthesis, comprising: an armature (2), adapted for deployment between a contracted position and an expanded implantation position; and a set of leaflets (3) coupled with said armature (2) for deployment therewith between the contracted position and the expanded position, the set of leaflets (3) defining, in the expanded position, a flow duct for the blood, which is selectively obstructable by the set of prosthetic valve leaflets (30) as a result of the reversal of the direct...
