D) Passage of the "J" guidewire
Advance the "J" guidewire provided into the kit (150 cm - diameter 0,89 mm /
0.035 in.). Follow its progress under fluoroscopy.
Warning :
To prevent the introducer from inadvertently passing outside of the IVC
(e.g. into a tributary vessel) verify that the "J" portion of the guidewire is located
above the renal veins.
Note :
In the event of difficulty advancing the guidewire because of the "J ",
remove the guidewire and use the other end, which is straight and supple.
E) Placement of the introducer
1. Insert the dilator into the introducer sheath.
Connect the Luer-Lock connecting the sheath and
dilator.
2. Place the introducer assembly over the "J"
guidewire. Advance it over the guidewire.
3. Continue to advance the introducer until the
marker is a little bit further than one cm
above the deployment site marker (hemostat)
placed on the abdomen.
Note :
The level of the marker on the introducer corres-
ponds to the top of the filter cone when it is
collapsed within the sheath prior to deployment.
This maneuver pre-positions the filter slightly above the level chosen for deploy-
ment. Withdrawing the sheath slightly adjusts the filter position before deployment.
Note :
Final adjustment of the filter position will be made just prior to
deployment.
Warning :
Hold the guidewire firmly as the introducer is advanced to prevent the
guidewire from moving or developing a kink.
