1. A valve holder assembly for a prosthetic valve having a stent comprising a stent ring and multiple commissure posts extending from the stent ring, the valve holder assembly comprising:
- a holder comprising;
a base ring having a central opening;
a plurality of legs extending in a generally downward direction from the base ring, each of the plurality of legs comprising a proximal end and a distal end; and
at least one flexible finger extending in a generally downward direction from the base ring,wherein the distal end of each of the legs is engageable with the stent ring between adjacent commissure posts;
a rotor positioned within the central opening of the base ring, the rotor comprising a proximal end, a distal end, a circumferential groove adjacent to the distal end of the rotor, and at least one ratchet arm at the proximal end of the rotor, wherein a portion of the at least one finger of the holder is engaged with the circumferential groove of the rotor; and
a handle extending from the proximal end of the rotor for rotation of the rotor relative to the holder.

14. A method of implanting a prosthetic valve in a patient, the prosthetic valve including a stent comprising a stent ring and multiple commissure posts extending from the stent ring, the method comprising the steps of:
-
providing a valve holder assembly comprising; a holder comprising a base ring having a central opening, a plurality of legs extending in a generally downward direction from the base ring, each of the plurality of legs comprising a proximal end and a distal end, wherein the distal end of each of the legs is engageable with the stent ring between adjacent commissure posts, and at least one flexible finger extending in a generally downward direction from the base ring; a rotor positioned within the central opening of the base ring, the rotor comprising a proximal end, a distal end, and at least one ratchet arm at the proximal end of the rotor, wherein a portion of the at least one finger of the holder is engaged with the circumferential groove of the rotor; and a handle extending from the proximal end of the rotor for rotation of the rotor relative to the holder; attaching the valve holder assembly to the stent of the prosthetic valve using a plurality of suture members; rotating the rotor relative to the holder to generally simultaneously deflect the multiple commissure posts of the stent inwardly; positioning the valve holder assembly with the attached prosthetic valve in an implantation site of a patient; attaching the prosthetic valve to the tissue of the patient; detaching the prosthetic valve from the valve holder assembly; and removing the valve holder assembly from the patient. - View Dependent Claims (15, 16)
