Abstract
A cardiac-valve prosthesis which can be used, for example, as a valve for percutaneous implantation. The prosthesis includes an armature for anchorage of the valve prosthesis in the implantation site. 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 contracted condition, in which the valve leaflets co-operate with one another and block the flow of the blood through the prosthesis in the opposite direction. The armature includes, in one embodiment, two annular elements connected by anchor members having the capacity of projecting radially with respect to the prosthesis, and support members for the set of leaflets, the support members being carried by at least one of the annular elements so as to leave substantially disengaged the aforesaid lumen for passage of the blood.
