16. Deflate the balloon and advance the contralateral wire guide into the
thoracic aorta.
NOTE: Due to early ipsilateral leg deployment and trigger-wire release,
it is suggested to leave the molding balloon in or just above the
contralateral limb for use in graft stabilization during placement of the
ipsilateral limb.
14.2.2 Docking of Top Cap
1. Loosen the pin vise. (Fig. 22)
2. Secure sheath and inner cannula to avoid any movement of these
components.
3. Advance the gray positioner over the inner cannula until it docks with the
top cap. (Figs. 23, 24 and 38)
NOTE: If resistance occurs, slightly rotate gray positioner and continue to
gently advance.
4. Retighten the pin vise and withdraw the entire top cap and gray
positioner through the graft and through the sheath by pulling on the
inner cannula. (Fig. 39) Leave the sheath and wire guide in place.
5. Close the Captor Hemostatic Valve on the Flexor introducer sheath by
turning it in a clockwise direction until it stops. (Fig. 26)
14.2.3 Ipsilateral Iliac Leg Placement and Deployment
NOTE: Ensure that the Captor Hemostatic Valve on the introducer sheath is
turned to the open position. (Fig. 27)
1. Position the image intensifier to show both the ipsilateral internal iliac
artery and ipsilateral common iliac artery.
2. After the introduction of the ipsilateral iliac leg delivery system, inject
contrast through the main body sheath to locate the ipsilateral internal
iliac artery.
3. Utilize the main body graft wire and sheath assembly to introduce the
ipsilateral leg graft.
NOTE: Due to top cap release modification, the main body sheath
assembly must be withdrawn to a point 1-2 cm inside the proximal
ipsilateral limb. Advance the dilator sheath assembly of the ipsilateral limb
into the main body sheath.
NOTE: The molding balloon may be inflated in the contralateral limb of
the main body graft if additional graft stabilization is necessary.
CAUTION: Do not inflate the balloon outside of the graft.
NOTE: In tortuous vessels, the position of the internal iliac arteries may
alter significantly with the introduction of the rigid wires and sheath
systems.
4. Advance the ipsilateral iliac leg delivery system slowly until the ipsilateral
iliac leg graft overlaps a minimum of one full iliac leg stent (i.e., proximal
stent of iliac leg graft) inside the ipsilateral limb of the main body.
(Fig. 40)
NOTE: If an overlap of greater than three iliac leg stents is required
(greater than two iliac leg stents for 37, 39, 54 and 56 mm leg lengths), it
may be necessary to consider use of a leg extension into the bifurcation
area of the opposite side.
5. Confirm position of distal end of the iliac leg graft. Reposition the iliac leg
graft if necessary to ensure internal iliac patency.
6. To deploy, stabilize the iliac leg graft with the gray positioner while
withdrawing the iliac leg sheath and main body sheath together. (Figs. 29
and 41)
7. Under fluoroscopy and after verification of iliac leg graft position, loosen
the pin vise, and retract the inner cannula to dock the tapered dilator
to the gray positioner. Tighten pin vise. Maintain sheath position while
withdrawing gray positioner with secured inner cannula. (Fig. 42)
8. Close the Captor Hemostatic Valve on the Flexor introducer sheath by
turning it in a clockwise direction until it stops.
9. Re-check the position of the wire guides. Leave sheath and wire guides in
place.
10. Remove deflated balloon from contralateral side.
14.2.4 Contralateral Iliac Leg Placement and Deployment
CAUTION: Verify the predetermined contralateral iliac leg is selected for
insertion on the contralateral side of the patient before implantation.
1. Position the image intensifier to show both the contralateral internal iliac
artery and contralateral common iliac artery.
2. Prior to introduction of contralateral iliac leg delivery system, inject
contrast through the contralateral femoral sheath to locate the
contralateral internal iliac artery.
3. Introduce the contralateral iliac leg delivery system into the artery.
Advance slowly until the iliac leg graft overlaps at least one full iliac leg
stent (i.e., proximal stent of iliac leg graft) inside the contralateral limb of
the main body. (Fig. 43)
NOTE: If using a Spiral-Z Iliac Leg, a radiopaque marker is positioned
30 mm from the proximal end of the iliac leg graft to identify the
maximum amount of overlap. To position this graft, advance slowly until
the iliac leg graft overlaps at least one stent and not past the radiopaque
marker band.
NOTE: If difficulty is encountered advancing the iliac leg delivery system,
exchange to a more supportive wire guide. In tortuous vessels, the
anatomy may alter significantly with the introduction of the rigid wires
and sheath systems.
4. Confirm position of distal end of the iliac leg graft. Reposition the iliac leg
graft if necessary to ensure both internal iliac patency and a minimum
overlap of one full iliac leg stent (i.e., proximal stent of iliac leg graft,
maximum overlap of 1.5 stents) within the main body endovascular graft.
5. To deploy, hold the iliac leg graft in position with the gray positioner while
withdrawing the sheath. (Figs. 18 and 44) Ensure one stent overlap is
maintained.
6. Stop withdrawing the sheath as soon as the distal end of the iliac leg graft
is released.
7. Under fluoroscopy and after verification of the iliac leg graft position,
loosen the pin vise, retract the inner cannula to dock the tapered dilator
to the gray positioner. Tighten pin vise. Maintain sheath position while
withdrawing gray positioner with secured inner cannula. (Fig. 45)
8. Re-check the position of the wire guides.
9. Perform molding balloon insertion and final angiogram as described in
the Molding Balloon Insertion section of the product‘s Instructions for
Use.
