1. A method for forming a proximal anastomosis of a graft vessel on a fluid-carrying vessel in a patient'"'"'s body, the method comprising:

  • forming an aperture in a wall of the vessel;

    introducing through the aperture and into the vessel in confined configuration a resilient, flexible sealing element having a central stem and having a continuous disassociation region formed thereon to extend from the central stem;

    expanding the sealing element to peripheral dimensions greater than the dimension of the aperture;

    retaining the sealing element in position covering the aperture in sealing engagement within the vessel;

    substantially completing anastomosing the graft vessel on the fluid-carrying vessel over the aperture, retaining an incomplete segment overlapping the central stem for removal of the sealing element;

    disassembling the expanded sealing element along the disassociation region extending from the central stem for removal thereof as a continuous strand through the incomplete segment; and

    completing the anastomosis of the graft vessel on the fluid-carrying vessel including along the incomplete segment.
