A vascular band (1) comprises a biocompatible flexible material (2) and a plurality of radiopaque bars (4) extending transversely across the width of the material and spaced apart along the length of the biocompatible material. The bars provide some rigidity to the flexible material in the width direction thereby preventing buckling of the band in use and the radiopaque nature of the bars enable visualization of a landing zone for a stent graft during deployment thereof. The bars can be crimped or woven into the material. The band can be stitched, stapled, or hooked around a vessel. |
