  • Patent number: 6416547
    Abstract: A carrier for heart valves allows the removal of a heart valve from the carrier without manual manipulation. In addition, the carrier minimizes or substantially eliminates leaking of preserving fluid during transportation and storage. The carrier includes ajar, a rinse cage, and a holder to which a heart valve is attachable. The rinse cage includes a first engagement structure, for example, a channel, and the holder includes a second engagement structure, for example, a groove, complementary to the first engagement structure for releasably engaging therewith. A heart valve attached to the holder is disposed or suspended within the rinse cage when the engagement structures are engaged. A heart valve attached to the holder is protected not only when within the jar but also when removed from the jar. The holder has a socket for engaging with a surgical handle used to remove the valve from the jar for rinsing and implantation.
