1. A delivery system for delivering and deploying a stent graft having distal and proximal stents, comprising:

  • a) a guidewire catheter having a proximal end and a distal end, and defining an interior extending along a longitudinal axis;

    b) a nose cone assembly at the distal end of the guidewire catheter, the nose cone assembly including a nose cone and a distal capture portion proximal to the nose cone, the distal capture portion being movable from a distal capture position to a distal release position by proximal movement of the distal capture portion;

    c) a proximal capture portion along the longitudinal axis and proximal to the distal capture portion of the nose cone assembly; and

    d) a stent graft including,i) a graft component having a proximal end and a distal end,ii) a proximal stent having proximal apices at the proximal end of the graft component, andiii) a distal stent having distal apices at the distal end of the graft component,wherein the proximal stent is secured to the distal capture portion and releasable by proximal movement relative to the stent graft of the distal capture portion from the distal capture position to the distal release position, and wherein the distal stent is releasably secured to the proximal capture portion.
