1. An assembly comprising:
- a prosthetic heart valve having a plurality of commissure supports and valve leaflets, said commissure supports terminating in free ends and at least one of said commissure supports being deflectable radially inwardly;
a valve holder;
means for attaching the heart valve to the valve holder with the valve holder being remote from the free ends of the commissure supports; and
means at least partially on the valve holder for deflecting at least said one commissure support radially inwardly;
said holder including inner and outer holder members with the inner holder member being between the outer holder member and the heart valve, means for mounting the holder members for movement toward and away from each other, said deflecting means including elongated flexible means coupled to the outer holder member and at least said one commissure support whereby movement of the outer holder member away from the inner holder member tensions the elongated flexible means to deflect said one commissure support radially inwardly.

Abstract
An assembly comprising a prosthetic heart valve having a plurality of commissure supports which are deflectable radially inwardly and a valve holder which includes inner and outer holder members mounted for movement toward and away from each other. The valve holder is attached to the heart valve by sutures which extend from the outer holder member to the commissure supports and then between the commissure supports. When a handle is attached to the other holder member, the holder members are forced apart to tension the sutures to deflect the commissure supports radially inwardly. Portions of the sutures extend between the commissure supports to form a suture loop guard.

2. An assembly comprising:
-
a prosthetic heart valve having a plurality of commissure supports and valve leaflets, said commissure supports being deflectable radially inwardly; a valve holder including inner and outer holder members with the inner holder member being between the outer holder member and the heart valve and means for mounting the holder members for movement toward and away from each other; and elongated flexible means coupled to the outer holder member and at least two of said commissure supports so that movement of the outer holder member away from the inner holder member tensions the elongated flexible means to deflect at least said two commissure supports radially inwardly. - View Dependent Claims (3, 4, 5, 6)

8. An assembly comprising:
-
a prosthetic heart valve having a plurality of commissure supports and valve leaflets, at least one of said commissure supports being deflectable radially inwardly and each of said commissure supports having a free end; a valve holder including first and second holder members and means for mounting the first holder member for movement relative to the second holder member; means for attaching the heart valve to the valve holder with the valve holder being remote from the free ends of the commissure supports; and means responsive to the movement of the first holder member relative to the second holder member for deflecting at least one of the commissure supports radially inwardly. - View Dependent Claims (9, 10, 11, 12, 13, 14)
