FIG 3. Digital radiographs of experimental simulation achieved by using Excel-14 microcatheter with GDC-10 2D, 8 mm x 30 cm

A, After coil detachment, before removal of pusher-wire. Note position of coil end (black arrow) and pusher-wire marker (white arrow) near proximal marker of microcatheter (arrowhead).

B, After brisk withdrawal of pusher wire. Note substantial coil retraction into microcatheter (white arrows)
