Device for replacing a cardiac valve by percutaneous route

A device (1) percutaneously replacement heart valve (55, 56) you located in a body passageway (50), comprising: - an elongated element (2) support; - A first set (11) of elongate members (30) arranged around the circumference of said elongate element (2); These elements (30) are pivotally attached to said elongate element (2) at their proximal longitudinal end; These elements (30) are pivotable relative to said elongate element (2) between a retracted position, in which they are located near the wall of the elongate member (2) so as not to oppose obstacle to the introduction and sliding of the device (1) within the body passageway (50) in which the valve (55, 56) is located, particularly within the aorta, and a deployed position in which these elements (30) are deployed; - A second series (12) of elements (30), dispuestosconsecutivamente to said first series (11) of elements in the distal direction, the elements (30) of this second series (12) of elements have an identical structure to that of elements (30) of said first series (11) of elements, unless these elements (30) of this second series (12) are attached to said elongated member (2) at their distal longitudinal ends.
