1. A vascular device to be prepared prior to insertion into a vessel with an aneurysm comprising:

  • a tubular stentless vascular graft having a proximal portion, a distal portion, and an outer surface having a diameter;

    a first docking head for positioning at the distal portion of the graft and consisting essentially of a thin-walled truncated cone having a lumen therethrough wherein the lumen of the first docking head has a diameter that corresponds to the diameter of the outer surface of the graft; and

    a second docking head for positioning at the proximal end of the graft and consisting essentially of a thin-walled truncated cone having a lumen therethrough wherein the lumen of the second docking head has a diameter that corresponds to the diameter of the outer surface of the graft,wherein each of the docking heads is adapted for insertion into a vessel to create a seal with a vessel wall without requiring expansion,wherein each of the docking heads has a portion and an exterior surface of the portion has a plurality of outwardly pointing flexible barbs that are inclined towards a longitudinal direction of the graft at a predetermined angle,wherein each of the first and second docking heads is adapted to be adjusted along and fastened to the graft at a suitable position on the outer surface of the graft to form the vascular device, prior to insertion into the vessel, andwherein distal and proximal portions of the vascular device are capable of being coupled within the vessel distally and proximally, respectively, substantially to healthy portions of the aneurysm in a suture-less and rapid manner.
