Abstract: An attachment member for securing a graft material to a vessel includes a conduit portion for attachment to the graft material. The attachment member has first and second anchor wings formed on opposite sides of an end of the conduit portion. The anchor wings are biased to extend substantially perpendicular to an axis of the conduit portion. The first and second anchor wings have arcuate shapes around substantially collinear axes for the anchor wings to define a flow path within a vessel on opposite sides of the conduit portion.

Abstract: An anastomosis device for securing a biocompatible conduit to a blood vessel. The conduit includes a first end and a second end. A resilient flange is positioned at the second end. The flange is movable between an expanded orientation and a compressed orientation and biased toward the expanded orientation. When the flange is compressed, it is adapted for insertion through an incision in a blood vessel. When the compression is released, the flange returns to its expanded orientation. The first end is adapted to be inserted into and retained within another anatomical structure creating an anastomosis between the blood vessel and the anatomical structure via the conduit. Other anatomical structures specifically include the heart wall of a heart chamber.
