1. A radially expandable prosthetic valve, comprising:
an annular frame comprising an inflow end and an outflow end and being radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration;
at least one expansion mechanism comprising a first member attached to the frame at a first location and a second member attached to the frame at a second location axially spaced from the first location;
a cord that extends through a first opening in the second member, extends at least partially along the second member in a first direction, is reeved around a cord routing member of the second member, extends at least partially along the second member in a second direction opposite the first direction, and extends through a second opening in the second member; and
wherein the cord routing member is spaced apart in an axial direction from both the first opening and the second opening, and
wherein applying a proximally directed force to a first portion of the cord causes the cord to move relative to the second member and the second member to move relative to the first member, which causes the frame to foreshorten axially and expand radially.
