1. A vascular repair device comprising:

  • a) a tubular graft body having a proximal end, a distal end, an interior surface and a longitudinal axis; and

    b) a structural framework having at least two stents, wherein;

    i) a first stent of the stents having first proximal apices and first distal apices each adjacent pair of first proximal apices and first distal apices defined by a single strut connecting respective adjacent ones of the first proximal and first distal apices, the first stent connected to the proximal end of the tubular graft body along an entirety of the first stent; and

    ii) a second stent of the stents having second proximal apices and second distal apices, each adjacent pair of second proximal apices and second distal apices defined by a single strut, the second proximal apices having a first radius of curvature and second distal apices having a second radius of curvature that is less than the first radius of curvature, the second stent connected to the proximal end of the tubular graft body at the second distal apices of the second stent and the second distal apices of the second stent nested between the struts and the first proximal apices of the first stent.
