11. A method of implanting a prosthetic valve, comprising:
inserting a delivery system with a prosthetic valve into a body lumen, the prosthetic valve comprising
a first expandable annular member having an inner lumen, and a longitudinal axis,
a valvular element disposed in the inner lumen of the first expandable annular member, and
a second expandable annular member connected by a connecting element to the first expandable annular member, the connecting element being a separate element from each of the first and second expandable annular members, the connecting element having a loop or eyelet for connecting with the first expandable annular member, wherein a circumference of the second expandable annular member is greater than a circumference of the first expandable annular member when the prosthetic valve is in an expanded configuration;
at least partially deploying the prosthetic valve at an implantation location to permit expansion of the second expandable annular member; and
proximally pulling the prosthetic valve to engage at least a portion of the second expandable annular member with a wall of the body lumen.
