8. Insert the dilator and sheath together over the mini guidewire, and into
the blood vessel (Fig. 4 and 4a).
9. "Unlock" the dilator hub from the sheath hub by bending the dilator hub
downward (Fig. 5).
10. Slowly remove the dilator and mini guidewire together, leaving the
sheath in the vessel (Fig. 6). If injection or sampling is necessary at this
point, remove the mini guidewire only, and use the dilator hub as an
injection port before removing it.
CAUTION
• Slowly remove the dilator from the sheath. Rapid withdrawal of the
dilator may result in the incomplete closing of the 1-way valve,
resulting in blood flow through the valve. If this occurs, replace the
dilator into the sheath and remove again slowly.
11. The radiopaque marker will provide sheath tip location under fluoros-
copy (the radiopaque marker is located approx. 5 mm proximal to the
sheath's tip – Fig. 4a). Insert a catheter through the sheath and into the
blood vessel, and advance to the desired location (Fig. 7).
