1. A prosthetic valve delivery assembly, comprising:
a prosthetic valve comprising an expandable frame having a plurality of apices at one end of the frame; and
a delivery apparatus, comprising:
a cord-retaining device comprising an annular body having an outer surface, the cord retaining device further comprising a plurality of circumferentially spaced tabs extending radially outwardly from the outer surface of the annular body;
one or more slideable release members extending through the cord-retaining device;
a plurality of separate cords, each comprising a first end portion comprising a first loop having a first opening and a second end portion comprising a second loop having a second opening;
a sheath advanceable over the prosthetic valve to retain the prosthetic valve in a radially compressed state, wherein the sheath can be retracted relative to the prosthetic valve to permit radial expansion of the prosthetic valve to a radially expanded state;
wherein each cord extends through an aperture in one of the apices or extends around one of the apices of the frame, wherein the first loop of each cord extends around one of the tabs, and wherein the second end portion of each cord is retained by one of the slideable release members extending through the second opening of the second loop;
wherein the one or more slideable release members can be moved axially relative to the second end portions of the cords to release the second end portions of the cords from the one or more slideable release members, thereby allowing the prosthetic valve to be released from the delivery apparatus.
