The invention is a method and system for anastomosis of a vein graft to an aorta comprising a novel anchoring means for affixing the vein to the aorta wall. The anchoring means for the vein graft comprises an expandible annular wire lattice having short radial projections to secure the lattice in the interior of the vein and longer, flexible prongs which are compressed against the outer wall of the vein while resident within the device, but which expand radially to prevent withdrawal of the vein from the aorta wall after the anchoring means is fully inserted into the aorta. The anchoring means is initially secured to the vein and advanced through a delivery sleeve by use of a balloon catheter.
