  • Patent number: 10426606
    Abstract: A color-coded bioprosthetic valve system having a valve with an annular sewing ring, and a valve holder system with a holder sutured to the ring of the valve, a post operatively connected to the holder, and an adapter sutured to the post and having a color associated with the valve model and/or size. For example, the adapter may be blue to indicate that the valve of the system is a mitral valve of a particular type and/or size. The system may also include a flex handle that is configured to engage with the adapter. The handle has a color associated with the adapter such that a user is able to visually determine that the handle color matches the valve model. For example, the handle may have a grip that is colored blue to match the blue color of the adapter. Accordingly, the color-coded system enables users to confirm easily that the correct accessories such as the sizer or flex handle are being used with the correct valve.

  • Patent number: 8839957
    Abstract: Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a sterile 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. A delivery handle on the end of a shaft couples with the valve holder while the packaging sleeve engages the jar to prevent rotation. The assembly of the packaging sleeve, valve, and holder can then easily be removed from the jar.

  • Publication number: 20080021546
    Abstract: A system and method for deploying balloon-expandable (i.e., plastically-expandable) prosthetic heart valves so that they assumed their desired operational shape. The system includes a balloon that accommodates non-uniform expansion resistance in the heart valve to expanded to its desired tubular or other shape. The heart valve may have substantially more structural elements adjacent one end, typically the inflow end, and the balloon is tapered so as to expand the inflow end before the outflow so that the valve ends up in a tubular shape. Alternatively, a stepped balloon with a larger diameter proximal section adjacent the inflow end of the valve may be used. A method includes applying a non-linear expansion forced to the interior of a plastically-expandable prosthetic heart valve to overcome areas of greater resistance to expansion and result in uniform expansion.
