Abstract:
1. A valve prosthesis adapted for implantation in a body vessel and having a lengthwise axis, said valve prosthesis comprising: a first frame element defining a serpentine path comprising a series of substantially straight strut portions interconnected by bends; a second frame element defining a path that includes first and second substantially straight struts disposed substantially parallel to each other and third and fourth substantially straight struts disposed substantially parallel to each other, the first and second substantially straight struts disposed circumferentially opposite the third and fourth substantially straight struts with respect to said lengthwise axis; one of the first and second frame elements further comprising an elongate strut that defines an outwardly-projecting curve with respect to said lengthwise axis, the outwardly-projecting curve adapted to define a sinus in said body vessel when said valve prosthesis is implanted therein; and a graft member attached to the first frame element and the second frame element, the graft member comprising a closure member adapted to move between a first position that allows fluid flow through said implantable valve prosthesis in a first, antegrade direction and a second position that restricts fluid flow through said implantable valve prosthesis in a second, retrograde direction; wherein the first and second frame elements are connected to each other only by attachments of the graft member to the first and second frame elements.
