Abstract

A valve holder for a prosthetic valve having a stent comprising a stent base and multiple commissure posts projecting from the stent base, the valve holder including a connector hub, a plurality of legs connected to the connector hub, each leg having an elongate portion and a commissure post engaging plate, a sliding member slideably connected to each leg of the plurality of legs and positioned between the connector hub and the commissure post engaging plates of the plurality of legs and slideably positionable at a first position relative to the connector hub with the commissure post engaging plates in an uncompressed configuration and a second position relative to the connector hub with the commissure post engaging plates in a compressed configuration, and a handle extending from the connector hub.

Claims

1. A valve holder for a prosthetic valve having a stent comprising a stent base and multiple commissure posts projecting from the stent base, the valve holder comprising:

a connector hub comprising a plurality of slots, wherein each of the slots comprises a one-way sliding mechanism;

a plurality of legs connected to the connector hub, each leg comprising an elongate portion and a commissure post engaging plate;

a sliding member slideably connected to each leg of the plurality of legs via at least one one-way sliding mechanism of the sliding member, wherein the sliding member is positioned between the connector hub and the commissure post engaging plates of the plurality of legs and slideably moveable from a first position relative to the connector hub in which the commissure post engaging plates are in an uncompressed configuration to a second position relative to the connector hub in which the commissure post engaging plates are in an at least partially compressed configuration; and

a handle extending from the connector hub;

wherein a portion of each of the plurality of legs is positioned within one of the slots of the connector hub.

2. The valve holder of claim 1, wherein the sliding member is closer to the connector hub when the sliding member is in its first position than when the sliding member is in its second position.

3. The valve holder of claim 1, wherein each leg of the plurality of legs comprises a plurality of teeth that can engage with the one-way sliding mechanism of the sliding member.

4. The valve holder of claim 1, wherein each commissure post engaging plate comprises a plurality of apertures spaced from each other to provide suture passages for a stitching sequence.

5. The valve holder of claim 1, wherein the commissure post engaging plate is at the distal end of the elongate portion.

6. The valve holder of claim 5, wherein the commissure post engaging plate comprises a first surface comprising a guide recess positioned generally between two adjacent apertures that can guide a cutting tool to a suture used to attach the commissure post engaging plate to a prosthetic valve.

7. The valve holder of claim 5, wherein the commissure post engaging plate comprises a first surface comprising at least one protective ridge that can guard against undesirably cutting a suture used to attach the commissure post engaging plate to a prosthetic valve.

8. The valve holder of claim 1, wherein the commissure post engaging plate comprises a recess in a second surface of the commissure post engaging plate that has a sufficient size to accommodate a suture knot.

9. The valve holder of claim 1, further comprising three legs spaced from each other around the connector hub.

10. The valve holder of claim 9, wherein the angle between a first leg and a second leg is about 105 degrees, the angle between the second leg and a third leg is about 120 degrees, and the angle between the first leg and the third leg is about 135 degrees.

11. The valve holder of claim 9, wherein three legs are spaced approximately evenly from each other around the connector hub.

12. The Valve holder of claim 1 in combination with a prosthetic valve.

13. The valve holder of claim 1, wherein the sliding member comprises a plurality of slots, and wherein a portion of each of the plurality of legs is positioned within one of the slots of the sliding member.

14. The valve holder of claim 13, wherein each of the plurality of slots of the sliding member comprises one of the one-way sliding mechanisms of the sliding member.
