seen in fig4 in further keeping with the invention as depicted in fig3 5 stent outer surface 26 is inserted within neck portion 11 of coupler 10 since coupler 10 is highly elastic it fits tightly over stent outer surface 26 and is attached thereto by bonding with known adhesives or suturing with a suitable biocompatible material similarly and with further reference to fig3 5 distal end 30 of graft 22 is attached to base portion 12 of coupler 10 as with the stent attachment graft 22 may he bonded or sutured to base portion 12 to firmly attach graft 22 to coupler 10 as another form of attachment coupler 10 is impregnated into the matrix fibers of the graft 22 material by a dipping process importantly graft 22 will he tightly folded along its longitudinal axis to its reduced profile delivery diameter as shown in fig3 and due to the elastic nature of coupler 10 it will assume the same folded configuration where it is attached to distal end 30 of the graft in one preferred embodiment of the invention as depicted in fig3 5 it is contemplated that stent 21 is bonded to coupler 10 such that it does not overlap or abut any portion of graft 22 also attached to coupler 10 when the graft coupler stent assembly 20 is mounted on a balloon catheter for delivery coupler 10 will be straightened in a longitudinal direction so that the entire assembly 20 has a low profile as depicted in fig3 this also assists in placing.
