  • Patent number: 5906642
    Abstract: A heart valve holder is provided for implanting a prosthetic heart valve in either an inflow (mitral or tricuspid) or an outflow (aortic or pulmonary) implantation. The valve holder may be repeatedly sterilized for multiple implantations. The valve holder includes holding members to securely hold the valve, a valve-sizing member to allow the holder to hold valves of various sizes, an over rotation stop to prevent the holder from impinging upon the valve leaflets, alignment members to align the holding members for receiving a valve, and means to rotate the valve without damaging the valve leaflets.

  • Patent number: 5823342
    Abstract: Packaging (10) for a heart valve device (11) is disclosed that includes a container (42) having an inner compartment. The container (42) has an aortic orientation and a mitral orientation and is constructed to be opened in either orientation. The packaging (10) also includes an aortic support member (22, 24, 26), located in the compartment, that supports the heart valve device (28) when the container (42) is opened in the aortic orientation. The heart valve device (11) is supported such that it is prepared for receiving a holding instrument for implantation as an aortic valve. The packaging (10) further includes a mitral support member (20), located in the compartment, that supports the heart valve device (11) when the container (42) is opened in the mitral orientation. The heart valve device (11) is supported such that it is prepared for receiving a holding instrument for implantation as a mitral valve.

  • Patent number: 5443502
    Abstract: A hinged heart valve holder and suturing method whereby the heart valve holder can be secured within a mechanical heart using a single suture. This suture operates both to secure the hinged heart valve holder within the annulus of the heart valve and to prevent the sewing ring from rotating on the annular valve body. Severing the suture at a single point both releases the heart valve holder and the sewing ring, permitting the annular valve body to be rotated within the sewing ring. Simultaneously, the suture remains secured to the heart valve holder and thus will be withdrawn in its entirety from the operation site.
