Abstract

A packaging assembly for storing a bioprosthetic heart valve without a liquid preservative solution is provided. The packaging system includes a holder, a cage, a storage tray and an insert sized to provide a cap over the cavity of the storage tray. The holder comprises a shaft and an engagement structure configured for removably attaching a bioprosthetic heart valve. The cage comprises an upper end, the cage configured to at least partially enclose the bioprosthetic heart valve. The storage tray comprises a cavity for housing the cage. The insert comprises 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. The insert defines a flat, generally planar disc comprising at least one of outward projections and flow passages. The packaging assembly does not comprise a liquid preservative solution.

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 cage comprising an upper end, the cage configured to at least partially enclose the bioprosthetic heart valve; and
a storage tray comprising a cavity for housing the cage;
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 , wherein the engagement structure of the holder comprises attachment sutures configured for removably attaching to a sewing ring of the heart valve.

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

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

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

9. The packaging assembly of claim 1 , 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.

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