<p>An implantable stent-graft (10) includes a radially distensible, tubular stent (20) having opposed open ends (12% 14') and a stent wall structure (16') having opposed exterior and luminal surfaces (30, 32); and a segmented, non-textile polymeric tubular structure (16) including a plurality of graft segments (18) circumferentially disposed about one of the stent surfaces (30, 32), the graft segments (18) including first portions (24) securably disposed to the one the stent surfaces (30, 32) and second portions (26) not securably disposed to the one the stent surfaces (30, 32); wherein adjacent graft segments (18) are disposed over one and the other to define overlaps (26'), the overlaps (26') forming a fluid tight seal when implanted in a body lumen.</p> |
