Abstract
Methods and apparatus for making an anastomotic connection between an opening at an end of a graft conduit and an aperture in a side wall of a body tissue conduit using a hollow connector assembly are provided, wherein the cross-sectional area of the anastomotic connection is larger than that of the graft conduit. The tissue about the opening is introduced about and retained by first members of a distal portion of the connector assembly held by a loading tool. A delivery tool then collapses a proximal portion defined by second members of the connector assembly and delivers the second members into the lumen of the body tissue conduit via the aperture. Upon inserting the second members into the body tissue conduit, the delivery tool is disemployed and the second members expand such that they press against the interior wall of the body tissue conduit and such that the first members are held within the aperture against a medial wall of the body tissue conduit.
