  • Note.—Average (mm) ± SD (minimum ∼ maximum); usual alignment refers to the marker alignment with which non-SyngerG GDC is advanced until the proximal end of the radiopaque marker on the delivery wire is exactly distal to the proximal marker on a microcatheter.

  • * An Excel-14 microcatheter with a long transparent zone of the catheter tip (1.68 mm) is excluded.
