Patent Images
1. A holder adapted for connection to a prosthetic valve in an assembled condition, the prosthetic valve including a stent having a plurality of commissure posts, the holder comprising:
- a base;
a plurality of legs extending in a direction from a first end connected to the base toward a free end, the direction including a component in an axial direction; and
a hub extending from the base in the axial direction, the hub having a plurality of pads extending radially outward and defining a circle having a hub diameter,wherein the commissure posts of the stent define a circle having a stent diameter, the stent diameter being greater than the hub diameter.

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.

5. A holder adapted for connection to a prosthetic valve in an assembled condition, the prosthetic valve including a stent having a plurality of commissure posts, the holder comprising:
-
a base; a plurality of legs extending in a direction from a first end connected to the base toward a free end, the direction including a component in an axial direction; a ring holder extending radially outward from each one of the plurality of legs; and a wire ring having a central axis and a plurality of substantially straight sides joined by a plurality of connectors, the plurality of substantially straight sides being spaced closer to the central axis than the plurality of connectors, the wire ring being mounted in the plurality of ring holders so as to surround the plurality of commissure posts and being rotatable about the central axis, the rotation of the wire ring causing the substantially straight sides of the wire ring to contact the commissure posts and deflect the commissure posts radially inward. - View Dependent Claims (6, 7)
