| 摘要 |
A side branch stent graft ( 1 ) suitable for the iliac arteries has a main tubular body ( 3 ) of a biocompatible graft material and a tubular side branch ( 5 ). The tubular side branch is affixed into the main tubular body so that a side branch lumen is in fluid communication with a main lumen. There is at least one external zig-zag stent ( 13 ) on the main tubular body proximal of the tubular side branch, one central external stent ( 14 ) which also encompasses the side arm, at least one external zig-zag stent ( 16 ) on the main tubular body distal of the tubular side branch and one internal zig-zag stent ( 15 ) at the distal end of the main tubular body. A reinforcing ring ( 9 ) is around the proximal end of the main tubular body and stitched thereto. |
