Abstract

Packaging for prosthetic heart valves including an assembly for stabilizing dry prosthetic tissue implants such as heart valves during storage. The packaging assembly can be used for storing a bioprosthetic heart valve without a liquid preservative solution. The packaging assembly can comprise a holder comprising an engagement structure configured for removably attaching a bioprosthetic heart valve, the holder comprising a shaft. The packaging assembly can also include a storage tray comprising a cavity and an insert sized to provide a cap over the cavity of the storage tray, the insert comprising a slot having a closed central end and an open outer periphery. The shaft of the holder can be non-rotatably retained at the closed central end, wherein the insert defines a flat, generally planar disc comprising at least one of outward projections and flow passages.

First claim

What is claimed is:

1. A packaging assembly for storing a bioprosthetic heart valve without a liquid preservative solution, the packaging assembly comprising:
a holder comprising an engagement structure configured for removably attaching a bioprosthetic heart valve, the holder comprising a shaft;
a storage tray comprising a cavity;
an insert sized to provide a cap over the cavity of the storage tray, the insert comprising a slot having a closed central end and an open outer periphery, the shaft of the holder being non-rotatably retained at the closed central end, wherein the insert defines a flat, generally planar disc comprising at least one of outward projections and flow passages; and
wherein the packaging assembly does not comprise a liquid preservative solution.

2. The packaging assembly of claim 1 , further comprising a cage comprising an upper end, the cage configured to at least partially enclose the bioprosthetic heart valve.

3. The packaging assembly of claim 2 , wherein the cage is stored in the cavity of the storage tray.

4. The packaging assembly of claim 2 , further comprising a clip member configured to be attached to the upper end of the cage, the clip member comprising a radial slot for receiving the shaft of the holder.

5. The packaging assembly of claim 3 , wherein the storage tray comprises a stepped ledge to suspend the cage within the cavity.

6. The packaging assembly of claim 5 , wherein the insert comprises outward projections and the storage tray comprises corresponding internal features and wherein the outward projections engage the internal features of the storage tray to limit rotational movement of the insert when positioned on the stepped ledge.

7. The packaging assembly of claim 5 , wherein the insert comprises flow passages and the storage tray comprises flow channels and wherein the flow passages align with the flow channels when the insert is positioned on the stepped ledge.

8. The packaging assembly of claim 1 , wherein the engagement structure of the holder comprises attachment sutures configured for removably attaching to a sewing ring of the heart valve.

9. The packaging assembly of claim 1 , wherein the holder comprises an upper bore having internal threads configured for attaching a delivery handle.

10. The packaging assembly of claim 1 , wherein the storage tray comprises flow channels.

11. The packaging assembly of claim 1 , wherein the insert comprises both outward projections and flow passages.

12. The packaging assembly of claim 1 , further comprising a gas-permeable lid configured to seal an open end of the storage tray.

13. A packaging assembly for storing a bioprosthetic heart valve without a liquid preservative solution, the packaging assembly comprising:
a holder comprising an engagement structure configured for removably attaching a bioprosthetic heart valve, the holder comprising a shaft and an upper bore having internal threads configured for attaching a delivery handle;
a storage tray comprising a cavity and flow channels;
an insert sized to provide a cap over the cavity of the storage tray, the insert comprising a slot having a closed central end and an open outer periphery, the shaft of the holder being non-rotatably retained at the closed central end, wherein the insert defines a flat, generally planar disc comprising both outward projections and flow passages; and
wherein the packaging assembly does not comprise a liquid preservative solution.

14. The packaging assembly of claim 13 , further comprising a cage comprising an upper end, the cage configured to at least partially enclose the bioprosthetic heart valve.

15. The packaging assembly of claim 14 , wherein the cage is stored in the cavity of the storage tray.

16. The packaging assembly of claim 14 , further comprising a clip member configured to be attached to the upper end of the cage, the clip member comprising a radial slot for receiving the shaft of the holder.

17. The packaging assembly of claim 15 , wherein the storage tray comprises a stepped ledge to suspend the cage within the cavity.

18. The packaging assembly of claim 17 , wherein the insert comprises outward projections and the storage tray comprises corresponding internal features and wherein the outward projections engage the internal features of the storage tray to limit rotational movement of the insert when positioned on the stepped ledge.

19. The packaging assembly of claim 13 , wherein the engagement structure of the holder comprises attachment sutures configured for removably attaching to a sewing ring of the heart valve.

20. The packaging assembly of claim 13 , further comprising a gas-permeable lid configured to seal an open end of the storage tray.
