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.

18. A valve device for implantation in a recipient vessel, said valve device comprising:
-
a bioprosthetic valve comprising a leaflet and a contiguous portion of a vessel wall harvested from a multi-leaflet vascular valve, the leaflet having a base portion attached to the contiguous wall portion; and an expandable support frame comprising one or more struts defining an outwardly projecting curvilinear portion configured to outwardly deflect a portion of the inner wall of the recipient vessel upon implantation therein; wherein the bioprosthetic valve is attached to the support frame and the base portion of the leaflet is positioned substantially adjacent the outwardly projecting portion such that a valve sinus region is formed between the outwardly deflected portion of the inner wall of the recipient vessel and the leaflet. - View Dependent Claims (19, 20, 21)

22. A delivery system for percutaneously delivering a valve device to a desired point of treatment in a recipient vessel, said delivery system comprising:
-
an elongate member having a proximal end, a distal tip adapted for insertion into and navigation through said recipient vessel, and a length from the proximal end to the distal tip, the elongate member including a device chamber adapted to receive an expandable medical device therein; a sheath disposed about the elongate member and over the device chamber, the sheath adapted to slidably move along the length of the elongate member; and a valve device for implantation in said recipient vessel, the valve device disposed within the device chamber and comprising a support structure and a bioprosthetic valve attached to the support structure, the bioprosthetic valve comprising a single leaflet and a contiguous portion of a vessel wall harvested from a multi-leaflet vascular valve, the contiguous portion including the natural margins of attachment between the leaflet and the vessel wall.
