    • This disclosure relates to a vascular connector device which has features that permit the connector device to close a vascular duct and to subsequently permit the vascular duct to be re-opened, if desired. The vascular connector of this disclosure features a tubular shaped vascular connector having a guillotine type plunger arrangement or assembly which can be actuated for first closing and then re-opening the vascular duct, if desired. Also disclosed are two separate clamp mechanisms in the form of special tongs with one used for initially actuating the guillotine type plunger arrangement to close off the vascular duct and the other clamp mechanism is used for achieving opening of the vascular duct by moving the guillotine type plunger arrangement into another position which causes the vascular duct to re-open by means of the restoration of an open conduit through the vascular duct because of the alignment of both previously separated portions of the vascular duct with an aperture in the guillotine type plunger mechanism.
    • 本公开涉及一种血管连接器装置,其具有允许连接器装置关闭血管导管并且随后允许血管导管重新打开的特征。 本公开的血管连接器的特征在于管状形状的血管连接器,其具有闸刀式柱塞装置或组件,如果需要,该闸管装置或组件可被致动以首先关闭然后重新打开血管。 还公开了具有特殊钳形式的两个单独的夹紧机构,一个用于初始致动闸刀式柱塞装置以关闭血管管道,另一个夹紧机构用于通过移动闸刀式柱塞来实现血管管道的打开 由于两个先前分离的血管管道部分与闸刀式柱塞机构中的孔的对准,使得血管通过通过血管导管的开口导管恢复而再次开启。
