1. A method for implanting a prosthetic heart valve, comprising:
- inserting a prosthetic heart valve in a contracted state into the body of a patient, said prosthetic heart valve having a plurality of valve leaflets and a support structure, the support structure comprising a plurality of self-expandable metallic panels being different from and configured to support the plurality of valve leaflets and said contracted state including at least one of said panels of the prosthetic heart valve being in an inverted state,introducing the prosthetic heart valve to a treatment site of a body lumen having a tissue wall, andexpanding the cross-sectional profile of the prosthetic heart valve into direct contact with the tissue wall of the body lumen, wherein expanding the cross-sectional profile comprises transitioning the at least one panel out of the inverted state.

Abstract
Prosthetic valves and their component parts are described, as are prosthetic valve delivery devices and methods for their use. The prosthetic valves are particularly adapted for use in percutaneous aortic valve replacement procedures. The delivery devices are particularly adapted for use in minimally invasive surgical procedures.

26. A method for implanting a prosthetic heart valve, comprising:
-
inserting a prosthetic heart valve in a contracted state into the body of a patient, said prosthetic heart valve having a plurality of valve leaflets and a support structure, the support structure comprising only three self-expandable metallic panels different from and configured to support the plurality of valve leaflets, wherein, in the contracted state, the prosthetic heart valve has a longitudinal axis and each panel of the prosthetic heart valve is inverted in a concave shape and curled towards the longitudinal axis, introducing the prosthetic heart valve to a treatment site in a body lumen having a tissue wall, and expanding the cross-sectional profile of the prosthetic heart valve into direct contact with the tissue wall of the body lumen, wherein expanding the cross-sectional profile comprises uncurling each of the panels away from the longitudinal axis and then transitioning each of the panels from the concave shape into a convex shape. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
