1. A method for delivering a valve prosthesis to a target location in a vessel of a subject, the method comprising:
introducing a delivery system into the vessel to position a valve anchor of the valve prosthesis at the target location;
proximally retracting a sheath of the delivery system to permit anchoring members of the valve anchor to expand for anchoring the valve anchor at the target location;
distally advancing a support frame of the valve prosthesis within the valve anchor while distally sliding a suture coupled to the support frame along an anchoring leg of the valve anchor, the suture sliding from a proximal position in which the suture provides a radial restriction on a proximal portion of the valve anchor to a distal position in which the radial restriction is relieved to thereby permit radial expansion of the proximal portion of the valve anchor; and
expanding the support frame within the valve anchor.
