④ Stent Deployment Procedure
PRECUATION: Do not twist introducer system or employ a
boring motion during the deployment as this may affect
positioning and ultimate function of stent
A. OTW(Distal Release System) & TTS Introducer System
a) Under the fluoroscope and/or endoscopic guidance, position
the introducer system to the center of the target stricture
exactly.
b) Once the introducer system is in the correct position for
deployment, unlock the proximal valve of the Y-connector by
turning the valve more than twice in an anti-clockwise
direction.
c) To begin stent deployment, immobilize the hub in one hand
and grasp the Y-connector with the other hand. Gently slide
the Y-connector back along the pusher towards the hub.
d) When the center X-ray marker reaches the center of target
stricture, continue pulling back on the Y-connector until the
stent is fully deployed. (See figure 4, 5)
CAUTION Do not push forward or pull backward on the hub
with the stent partially deployed. The hub must be securely
immobilized. Inadvertent movement of the hub may cause
misalignment of the stent and possible damage to the target or
stricture.
B. OTW(Proximal Release System)
a) Under the fluoroscope and/or endoscopy guidance, position
the introducer system to the center of target stricture exactly.
b) Once the introducer system is in the correct position for
deployment, unlock the proximal valve of the Connector by
turning the valve more than twice in an anti-clockwise
direction. The stent is now ready for deployment
c) To begin stent deployment, immobilize the Connector in one
hand and grasp the hub with the other hand. Gently slide the
hub forward along the 2
Connector.
d) When the center X-ray marker reaches the center of target
stricture, continue forwarding toward the connector until the
stent is fully deployed. (See figure 4, 6)
