ABSTRACT:
A percutaneously deliverable heart valve prosthesis and method of delivery, wherein the prosthesis is anchored to a valvular annulus of a patient and used to replace the patient's diseased valve. The prosthesis is supported by a rigid frame that is generally fixed, but capable of being modified between a first collapsed position and a second expanded position. In its first collapsed position, the prosthesis has sufficient flexibility and is of such a low profile that it allows for easy percutaneously delivery. Upon proper delivery, the prosthesis is anchored and modifiable to a generally permanent expanded position sufficiently rigid to resist the strong recoil force exerted by a distorted stenosed valve orifice displaced by the prosthesis.
