The present disclosure relates to a medical anchor device and methods of use for providing an improved device for intraluminally directed vascular anastomosis. The anchor device includes a generally tubular graft having a flange disposed at one end thereof, where a portion of the graft extends through the flange. The flange includes a wire frame made of a resilient material and a thin membrane covering or overlaying the wire frame, where the wire frame is self-expanding when deployed within a lumen. The device may be deployed within the lumen at an anastomotic site without a need for sutures, staples, clips, or other mechanical attachment means that may cause further injury.
