7. To recapture stent, push direction button on side of delivery system to opposite side. (See
Fig. 3) Note: Hold thumb on button when squeezing trigger for first time to recapture.
8. Continue squeezing trigger as required to recapture stent by desired amount.
9. To resume deployment, push button to opposite side again and hold thumb on button for
first stroke while squeezing trigger. (See Fig. 4)
10. When stent point-of-no-return has been passed, pull safety wire out of delivery handle
near wire guide port. (See Fig. 5)
11. Continue deploying stent by squeezing trigger.
12. After deployment, fluoroscopically confirm full stent expansion. Once full expansion is
confirmed, introduction system can be safely removed. Note: You may introduce endoscope
and advance to the upper margin of the stent to endoscopically confirm position and patency
of the stent. Warning: Do not introduce the endoscope into the stent as displacement may
occur.
