1. An elliptical prosthetic valve comprising:
- an elliptical support means having a longitudinal axis, an interior surface and an outer surface, the interior surface defining an internal lumen containing the longitudinal axis, the elliptical support means configured to conduct fluid flow through the internal lumen, and the outer surface having an elliptical cross-sectional shape, the outer surface intersecting a first radial axis at a first distance and intersecting a second radial axis perpendicular to the first radial axis at a second distance that is less than the first distance, the first radial axis and the second radial axis being perpendicular to the longitudinal axis;
wherein the elliptical support means comprises an elliptical ring comprising a first pair of collapse points positioned at the points of intersection of the first radial axis with the elliptical ring;
the elliptical ring moveable from a planar configuration bisected by a first plane containing the first radial axis and the second radial axis, to a bent configuration by bending the planar elliptical ring at the first pair of collapse points while moving the points of intersection of the elliptical ring with the second radial axis out of the first plane; and
a means for regulating fluid flow through the internal lumen, the means for regulating fluid flow being attached to the elliptical ring.

Abstract
Elliptical prosthetic valve devices are provided. The prosthetic valve device can include an elliptical support means having an elliptical cross-sectional shape and having an opening for fluid flow therethrough. The elliptical support is preferably characterized by a first radial axis and a second, shorter radial axis perpendicular thereto. A flexible valve member, such as a tube member portion or valve leaflet, can be operably connected to the elliptical support and the flexible member is adapted for regulating fluid flow through the opening. An attachment portion is desirably operably connected to the elliptical support for implanting the valve in the body vessel.
