  • Patent number: 11027870
    Abstract: Packaging for dry prosthetic tissue heart valves and their delivery systems includes a primary sterile barrier that permits gas sterilization of the tissue implant, and a secondary sterile barrier that also prevents oxidation of the implant during long-term storage. Dry tissue heart valves and their delivery systems are placed within a primary container such as a rigid tray that limits movement of the components therein. The primary container is placed within a secondary container, such as another rigid tray or a flexible pouch, and the assembly is then sterilized. The outer sterile barrier may include a double seal so that a first gas-permeable seal can be closed for sterilization, after which a second gas-impermeable seal can be closed to seal out any further oxygen contact with the tissue implant. A collapsible delivery handle for a surgical heart valve may be provided which reduces the size of the packaging, and is useful for various types of prosthetic heart valves.

  • Publication number: 20200179093
    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 have a valve holder configured for removably attaching a bioprosthetic heart valve, a storage tray comprising an open end and a cavity, and a retaining member configured for removably attaching the valve holder. The retaining member can be generally planar and have a slot having a closed end and an open outer end. The valve holder can be configured to be retained at the closed end of the slot in the retaining member.

  • Patent number: 10561486
    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.

  • Publication number: 20180228605
    Abstract: Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a jar and facilitating retrieval therefrom. The assembly includes a packaging sleeve that fits closely within the jar and has a clip structure for securing a valve holder. Contrary to previous designs, in one embodiment the valve holder is directed downward into the jar, and the valve is retained with an inflow end upward. The valve may have flexible leaflets, and a leaflet parting member on the end of the shaft extends through the leaflets and couples with the valve holder. The assembly of the packaging sleeve, valve, and holder can then be removed from the jar and a valve delivery tube connected with the holder, or to the leaflet parting member. The packaging sleeve may be bifurcated into two halves connected at a living hinge to facilitate removal from around the valve/holder subassembly.
