Claim Text:
1. A medical device for treating a diseased native heart valve having sinuses and native leaflets, comprising: a prosthetic valve; and a metallic support structure for supporting the prosthetic valve, the support structure comprising: a first plurality of arms configured to be respectively positioned within the sinuses of the diseased native heart valve, wherein each of the first plurality of arms includes a substantially U-shaped or V-shaped structure having a downstream open end and an upstream closed end, and wherein each of the first plurality of arms is biased to pivot radially outward from a longitudinal axis of the medical device without outside forces acting upon the first plurality of arms, and a second plurality of arms, wherein each of the second plurality of arms includes a substantially U-shaped or V-shaped structure, wherein each of the first plurality of arms is associated with each of the second plurality of arms such that a native leaflet of the native heart valve is radially between each associated first arm and second arm when the medical device is implanted such that each first arm is radially outside a native leaflet of the native heart and each second arm is radially inside and in contact with a native leaflet of the native heart, and wherein each downstream end portion of a respective first arm is joined to a downstream end portion of an associated second arm by a strut support extending substantially in the longitudinal direction of the prosthesis.
