1. A removable repair assembly for placement in a blood vessel which comprises:

  • an elongate tubular graft having an interior surface, an exterior surface, a proximal end, a distal end, and an axial length; and

    an anchor assembly having a proximal end, a distal end and an axial length greater than the axial length of the graft;

    the anchor assembly having, at each end, an anchor that is radially resiliently expandable from a radially contracted to a radially expanded configuration, the proximal and distal anchors being connected to each other by at least two longitudinal struts, each of the struts extending between the proximal and distal anchors;

    the struts being connected to the proximal and distal anchors to cause a radial contraction force applied at one of the anchors to be transmitted to the other of the anchors, the struts serving to maintain the lengthwise positions of the proximal and distal anchors, the struts being arranged in the repair assembly such that they do not develop any radially outward expansion force independently of their connection to the proximal and distal anchors;

    the end of at least one of the anchors protruding beyond its associated end of the graft and defining a connector for direct, rigid connection to a delivery device.
