Claims 34 and 35 are representative.
34. A modular endoluminal stent-graft system for bridging a lesion in
a blood vessel, each stent-graft of said modular stent-graft system having a
contracted state for intraluminal insertion into the vessel and an expanded
state upon deployment in the vessel, said modular stent-graft system
comprising, in its expanded state:
a first stent-graft having a first proximal end and a first distal end,
wherein the first distal end is smaller than the first proximal end;
a second stent-graft having a second proximal end engaging the first
distal end and a second distal end, wherein the second distal end is not larger
than the second proximal end; and
a third stent-graft having a third proximal end engaging the second
distal end and a third distal end, wherein the third distal end is smaller than
the third proximal end.
35. A modular endoluminal stent-graft system for bridging a lesion in
a blood vessel, each stent-graft of said modular stent-graft system having a
contracted state for intraluminal insertion into the vessel and an expanded
state upon deployment in the vessel, said modular stent-graft system
comprising, in its expanded state:
a large stent-graft having a first end that is larger than a second end;
a small stent-graft having a first end that is larger than a second end;
and
an intermediate stent-graft having a first end engaging the second end
of the large stent-graft and a second end engaging the first end of the small
stent-graft, wherein the intermediate stent-graft has a generally constant
diameter between its first and second ends.
