- Fig 1.
Excel 14 catheter, demonstrating 7-mm length and manually steam-shaped 90° angle curve. Although the initial measured tip angle measured 98° (I), the tip angle decreased to 75° following coaxial microcatheter insertion through a guiding catheter (CI). The tip angle was further reduced to 46° following guidewire manipulation (GW). The tip angle recovered to approximately 60° after the second (C2) and fifth GDC withdrawals and insertions (C5). The change rate of the catheter-tip angles, once exposed to straightening forces, is graphically depicted as a percentage straightening when compared with the initial baseline-shaped angle.
- Fig 2.
Change rate without stress on 5- and 7-mm lengths of steam-shaped catheter tip. After insertion through a guiding catheter (CI), measurement was performed at 5, 15, and 30 minutes. Exc14 indicates Excel 14; Fas10, FasTracker 10; I, initial measurement; Prow14, Prowler 14; ProwPS, Prowler 14 Preshaped; and SL10, Excelsior SL 10.
- Fig 3.
Change rate with stress on 3-, 5-, and 7-mm lengths of steam-shaped catheter tip. CI indicates coaxial microcatheter insertion through a guiding catheter; C2, after second GDC insertions and withdrawals; C5, after fifth GDC insertions and withdrawals; Exc14, Excel 14; Fas10, FasTracker 10; GW, microguidewire manipulation; I, initial measurement; Prow14, Prowler 14; ProwPS, Prowler 14 Preshaped; and SL10, Excelsior SL 10.
