Deployment of the Stent
11. Before deployment, it is important to straighten the proximal part of the
introducer catheter as much as possible and to keep the handle in a stable
position.
12. The stent expansion must be performed under fluoroscopic control.
13. Hold the hub (
remove the red safety lock (c). (Fig. 3) Hold the hub end stationary. The
stent will be deployed as you pull the handle (a) toward the hub (b).
(Fig. 4)
NOTE: Care should be taken to hold the hub (b) stationary and to remove
any slack in the introducer catheter to ensure the stent is not stretched
or compressed lengthwise during deployment (i.e., so that the stent is
deployed to its proper length). Full deployment of the stent length will
occur when the distal end of the sheath has been retracted past the
proximal part of the stent.
14. As deployment occurs, continue sliding the handle (a) toward the hub (b)
in a slow, smooth and consistent fashion. (Fig. 5)
NOTE: Once stent deployment has begun, the stent must be fully
deployed. Repositioning of the Zilver PTX Drug Eluting Peripheral
Stent is not possible since the delivery system's outer sheath cannot be
re-advanced over the stent once deployment begins. Refer to the Multiple
Stent Placement section of these Instructions For Use for information on
missed lesions.
