1. A valve device for implantation in a recipient vessel, said valve device comprising:
- an expandable support frame having a longitudinal axis, a radially compressed configuration, a radially expanded configuration, and comprising first and second connector segments disposed substantially opposite each other with respect to the longitudinal axis, and a third connector segment disposed circumferentially between the first and second connector segments with respect to the longitudinal axis, the first connector segment including substantially straight first and second struts that are substantially parallel to each other in the radially expanded configuration, the second connector segment including substantially straight third and fourth struts that are substantially parallel to each other in the radially expanded configuration, and the third connector segment defining an outwardly-projecting curve; and
a bioprosthetic valve attached to the support frame along the first, second, and third connector segments, the bioprosthetic valve comprising a single leaflet and a contiguous portion of a vessel wall harvested from a multi-leaflet vascular valve, the leaflet defining a free edge and having an inside surface disposed substantially opposite the third connector segment with respect to the longitudinal axis;
wherein the contiguous portion of a vessel wall harvested from a multi-leaflet vascular valve comprises a non-circumferential portion of a vessel wall harvested from a multi-leaflet vascular valve.

Abstract
Valve devices, methods of making valve devices, and methods of treating various venous-related conditions, disorders and/or diseases are described. In one embodiment, a valve device includes an expandable support frame and a bioprosthetic valve attached to the support frame. The bioprosthetic valve comprises a leaflet and a contiguous wall portion harvested from a multi-leaflet xenogeneic valve. The contiguous wall portion includes the attachment region where the leaflets attaches to the vessel wall and, in some embodiments, includes the natural margins of attachment between the leaflet and vessel wall.
