ABSTRACT:
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.
