EQUIPMENT REQUIRED

Stent and delivery system
.035 inch wire guide
SELECTION OF STENT
A stent length of at least 4 cm longer than the stricture is recommended
(e.g. approximately 2 cm longer at either end of the stricture)

PATIENT PREPARATION

1. Place wire guide through the stricture.
INSTRUCTIONS FOR USE
Illustrations
1. Remove protective tubing from stent.
2. Introduce delivery system in short increments over wire guide, into
accessory channel, until it is endoscopically visualized exiting scope.
3. To ensure that stent will bridge stricture after deployment,
fluoroscopically position radiopaque markers on inner catheter beyond
extremities of stricture to be crossed. Note: Yellow marker on the
delivery system located at the proximal end of stent can also serve as
an endoscopic/fluoroscopic reference for positioning of the proximal
(nearest user) end of the stent relative to the stricture.
4. Confirm desired stent position fluoroscopically and deploy stent by
removing red safety guard from the handle. (See Fig. 1)
5. Continue deploying stent by squeezing trigger. Note: Each trigger
squeeze will deploy stent by an equal amount.
6. If stent repositioning is required during deployment, it is possible to
recapture stent. Note: It is not possible to recapture stent after passing
point-of-no-return, indicated when red marker on top of introducer has
passed the point-of-no-return indicator on handle. (See Fig. 2)
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.
