1. A system for engrafting in a fluid conducting corporeal lumen comprising:

  • a hollow graft of preselected cross-section and length having a proximal end and a distal end for placement within said corporeal lumen, said hollow graft being deformable to substantially conform to the interior surface of said corporeal lumen;

    a proximal staple positioned proximate the proximal end of said graft, said proximal staple being formed and positioned to urge said hollow graft against said interior surface and having lumen engaging members positioned and adapted for holding said proximal end of said hollow graft to and within said corporeal lumen;

    a distal staple positioned proximate the distal end of said hollow graft, said distal staple being formed and positioned to urge said hollow graft against said interior surface and having lumen engaging members positioned and adapted for holding said distal end of said hollow graft to and within said corporeal lumen; and

    placement means for introducing and carrying said hollow graft with said proximal staple and said distal staple into and within said corporeal lumen and for placing and engrafting said hollow graft with said proximal and distal staples at a preselected position within and to said corporeal lumen by advancing the hollow graft to the preselected position, said placement means including a cylindrical capsule sized and shaped for positioning in and movement through said corporeal lumen and formed to have an interior sized and shaped to receive said hollow graft with said proximal and distal staples, said cylindrical capsule having proximal and distal extremities, said distal extremity having an aperture formed therein for passage therethrough of said hollow graft with said proximal and distal staples.
