12. A prosthetic valve delivery system, comprising:
-
a prosthetic valve, comprising; an expandable stent including an inner lumen and having a first and a second end; a valvular element disposed in the inner lumen of the expandable stent; and a spring attached to the first end of the expandable stent; wherein the expandable stent and the spring can expand radially to a desired diametric configuration once deployed in order to anchor the prosthetic heart valve at an implantation position in a body lumen; and a sheath comprising a distal end and a lumen in which the prosthetic valve is positioned prior to deployment of the prosthetic valve and out of which the prosthetic valve is deployed at the implantation position. - View Dependent Claims (13)

14. A method of implanting a prosthetic valve, the method comprising the steps of:
-
inserting a system into a body, the system comprising; a prosthetic valve, comprising; an expandable stent including an inner lumen and having a first and a second end; a valvular element disposed in the inner lumen of the e expandable stent; and a spring attached to the first end of the expandable stent; wherein the expandable stent and the spring can expand radially to a desired diametric configuration once deployed in order to anchor the prosthetic valve at an implantation position in a body lumen; and a sheath comprising a distal end and a lumen in which the prosthetic valve is positioned prior to deployment of the prosthetic valve and out of which the prosthetic valve is deployed at the implantation position; advancing the system to the implantation position; and deploying the prosthetic valve to the desired diametric configuration to anchor the prosthetic valve at the implantation position. - View Dependent Claims (15, 16, 17)
