7.3.3 lesion Preparation

Carefully catheterize the lesion to be treated. The access system should include
a guiding catheter of sufficient inner diameter (ID) to accept a 2-tip microcatheter
and to permit adequate contrast infusion around the 2-tip microcatheter for
fluoroscopic road mapping. Measure the size of the aneurysm to be treated and
select an appropriately sized Target Detachable Coil.

7.3.4 Target Detachable Coil Preparation

1. Verify the packaging is intact. Do not use a Target Detachable Coil if packaging
is damaged.
warning: Do not use the product after the "Use By" date specified on the
package.
2. Within the sterile field, open pouch containing the packaging hoop and remove
the hoop from the pouch.
3. Locate the proximal end of the introducer sheath between the white wire
retainer and orange sheath retainer.
4. Carefully grasp the wire and introducer sheath together and remove the
delivery wire from the white wire retainer and orange sheath retainer, taking
care not to kink the delivery wire (See Figure 2).

5. While grasping the wire and introducer sheath together, slide the Target
Detachable Coil straight out of the packaging hoop taking care not to damage
the delivery wire (See Figure 2).
warning: Reuse of the packaging hoop or use with any coil other than the
original coil may result in contamination of, or damage to, the coil.
Caution: Removing the delivery wire without grasping the introducer sheath
and delivery wire together (Figure 2) may result in the detachable coil sliding
out of the introducer sheath.

7.4 Target Detachable Coil Delivery Procedure

1. Inspect the proximal section of the delivery wire for irregularities, such
as kinks or roughness. If irregularities exist, replace with a new Target
Detachable Coil.
warning: Damaged delivery wires may cause detachment failures, vessel
injury or unpredictable distal tip response during coil deployment. If a
delivery wire is damaged at any point during the procedure, do not attempt
to straighten or otherwise repair it. Do not proceed with deployment or
detachment. Remove the entire coil and replace with undamaged product.
warning: Utilization of damaged coils may affect coil delivery to, and stability
inside, the vessel or aneurysm, possibly resulting in coil migration and/or
stretching.
