1. A method of implanting a prosthesis at an implantation site proximate a native aortic valve to be repaired, the implantation site including a valve annulus and three Valsalva sinuses located distal to the valve annulus, the method comprising:

  • positioning the prosthesis at the implantation site in a radially collapsed configuration, the prosthesis including an armature and a valve connected to the armature, the armature including a proximal portion, a distal portion, and first, second and third Valsalva sinus anchors each extending between and connecting the proximal and distal portions, wherein positioning the prosthesis includes positioning the prosthesis so that the first, second and third Valsalva sinus anchors are each positioned so that they can project into a respective one of the Valsalva sinuses of the implantation site;

    radially expanding the prosthesis such that each of the Valsalva sinus anchors arches radially outward from the proximal portion to the distal portion and extends into and engages a wall of a respective one of the Valsalva sinuses so as to enable anchorage of the prosthesis at the implantation site.
