The prosthetic device includes an expandable metal base (10) constructed so as to be implantable in the expanded state of the prosthetic device in the aortic annulus of the aortic valve; and an inner envelope lining (11) tune inner surface of the metal base (10). The inner envelope, in the expanded state of the prosthetic device, extends into the aorta and is of a diverging conical configuration, in which its diameter gradually increases from its proximal end within the aortic annulus to its distal end extending into the aorta, such as to produce, during systole, a non-turbulent blood flow into the aorta with pressure recovery at the distal end of the inner envelope. Preferably, the distal end includes a prosthetic valve which is also concurrently implanted, but such a prosthetic value may be implanted separately in the aorta. Also described are preferred methods of implanting such prosthetic devices.WO 2005/002466 PCT/IL2004/000601 5/11 114 113 Fig. 12 112 110 114111 113 112a Fig. 13 110 112 110 1112 Fig. 14
