Patent ID: 7569071

Claim:
A venous valve frame, comprising: a first structural member that defines an elongate base portion having a first end, a second end, and an outer surface concentrically arranged relative a longitudinal axis, where the outer surface provides at least two points of a perimeter of a first elliptical plane orthogonal to and passing through the longitudinal axis, and where the first structural member at each of the first end and the second end includes a first curve and a second curve opposite the first curve with the first curve and the second curve of the first end positioned radially orthogonal to the first curve and the second curve of the second end of the base portion; a second structural member that extends between the first end and the second end of the elongate base portion to define a bulbous portion, where the outer surface of the elongate base portion and the second structural member provide at least four points of a perimeter of a plane orthogonal to the longitudinal axis, where the plane has an area that is greater than the area of the first elliptical plane; and a valve leaflet connection location along the first structural member of the venous valve frame.
