11.3 Iliac Legs and Iliac Leg Extensions

The iliac leg extensions (Fig. 4) are used for extending the distal iliac legs
and/or bridging an in situ endovascular graft . If an iliac leg extension is not
available, an iliac leg (Fig. 3) can be used . If using an iliac leg/iliac leg
extension as part of primary repair, the iliac leg/iliac leg extension delivery
system may be introduced through an existing in situ 18, 20 or 22 French
introduction system sheath .

Iliac Leg Extension Preparation/Flush

1 . Remove the gray-hubbed shipping stylet (from the inner cannula) and
dilator tip protector (from the dilator tip) . Remove Peel-Away sheath from
the back of the hemostatic valve . (Fig. 18) Elevate distal tip of system and
flush through the stopcock on the hemostatic valve until fluid emerges
from the flushing groove near the tip of the introducer sheath . (Fig. 8)
Continue to inject a full 20 cc of flushing solution through the device .
Discontinue injection and close stopcock .
NOTE: Graft flushing solution of heparinized saline is often used .
2 . Attach syringe with heparinized saline to the hub on the inner cannula .
Flush until fluid exits the dilator tip . (Fig. 9)
NOTE: When flushing system, elevate distal end of system to facilitate
removal of air .
3 . Soak sterile gauze pads in saline solution and use to wipe Flexor
introducer sheath to activate the hydrophilic coating . Hydrate both sheath
and dilator liberally .

Iliac Leg Extension Placement and Deployment

1 . Replace J tip wire guide with stiff wire guide (LES), .035 inch, 260 cm long,
and advance through catheter and up to the thoracic aorta . Remove flush
catheter and sheath . Maintain wire guide position .
2 . Introduce the iliac leg extension delivery system into the artery .
NOTE: If the Zenith Flex AAA Endovascular Graft main body delivery system is
being utilized to introduce the iliac leg extension, ensure the Captor
Hemostatic Valve is in the open position prior to introduction and
deployment of the iliac leg extension .
3 . Advance slowly until the iliac leg extension is at the site of the required
intervention . (Fig. 19) Ensure that a proper placement is achieved . Verify
appropriate stent graft overlap to ensure proper sealing and resistance to
migration .
4 . Verify placement with angiography to ensure the internal iliacs will remain
patent .
NOTE: Ensure the Captor Hemostatic Valve on the Flexor introducer sheath is
turned to the open position . (Fig. 11)
5 . Use the gripper to stabilize the gray positioner while withdrawing the
sheath . (Figs. 12 and 20)
6 . Continue to deploy the device until the distal stent is uncovered . (Fig. 21)
Stop withdrawing the sheath .
7 . Withdraw the tapered tip of the introducer back through the iliac leg
extension graft and sheath while maintaining wire guide position . Ensure
the endovascular graft is not displaced during withdrawal of delivery
system .

iliac artery .
CAUTION: Maintain wire guide position during delivery system insertion.
NOTE: The iliac plug is tethered to the gray positioner, which allows the iliac
plug to be repositioned within the vessel .

Iliac Plug Deployment

NOTE: Ensure the Captor Hemostatic Valve on the Flexor introducer sheath is
turned to the open position .
1 . Verify position of wire guide in the iliac artery . Deploy the iliac plug
by withdrawing the sheath while stabilizing the gray positioner of the
delivery system with the gripper . Withdraw the sheath until the iliac plug
is uncovered . (Figs. 31 and 32) Stop withdrawing sheath .
2 . Remove the safety lock from the trigger-wire release mechanism .
Withdraw and remove the trigger-wire by sliding the trigger-wire release
mechanism off the handle, and then remove via its slot over the inner
cannula . (Fig. 33)
3 . Perform angiography to verify position of the iliac plug with respect to the
internal iliac artery .
4 . Withdraw the wire guide while maintaining position of the gray positioner .
Ensure the endovascular graft is not displaced during withdrawal of wire
guide .
5 . Slowly withdraw gray positioner . Ensure the endovascular graft is not
displaced during withdrawal of gray positioner .

Iliac Plug Molding Balloon Insertion

NOTE: The expandable length of the Zenith AAA Iliac Plug is 30 mm . To avoid
inflation of molding balloon outside the distal aspect of the plug, the balloon
should fit within the expandable length of the plug .
