1. A prosthetic valve implantation system comprising:
- a prosthetic valve including a stent having a plurality of commissure posts, and a valve assembly mounted within the stent; and
a holder adapted for connection to the prosthetic valve in an assembled condition, the holder including;
a base having an axis extending in an axial direction;
a plurality of legs each extending in a direction from a first end connected to the base toward a free end, the direction including a component in the axial direction;
a ring holder extending radially outward relative to the axis of the base from each one of the plurality of legs; and
a wire ring having a central axis and a plurality of sides joined by a plurality of connectors, the plurality of sides being spaced closer to the central axis than the plurality of connectors, the wire ring being mounted in the ring holders in the assembled conditions so as to surround the plurality of commissure posts and being rotatable about the central axis, the rotation of the wire ring causing the sides of the wire ring to contact the commissure posts and deflect the commissure posts radially inward.

Abstract
A valve holder is connectable to a prosthetic valve including a stent having a plurality of commissure posts. The valve includes a base, a plurality of legs extending from the base, and one of several mechanisms for deflecting the plurality of commissure posts radially inward so as to temporarily decrease the overall size of the prosthetic valve.
